Eve Spectrum 4K Monitor Review
Today nosotros're taking a look at a very heavily requested monitor, the Eve Spectrum 4K which is a 'oversupply-designed' project just as they had washed before with the Eve V tablet we reviewed a few years back. Now, as office of this review, we decided to buy a Spectrum 4K considering Eve doesn't have a great rail record equally a company in delivering products on time as promised. The Eve V tablet was a pretty good product, just it was plagued with production issues and delays, and the refund process was poor to say the least, judging by various user reports.
Eve did offer us a monitor review unit of measurement, but we wanted to assess whether they would actually deliver a monitor to us after pre-ordering, and to see what the whole process is similar. We were somewhat concerned that the product could be a scam – if they took pre-orders and never shipped units to customers beyond the start wave and to reviewers. So we secretly shopped this monitor to a different address and details so Eve wouldn't know it was the states.
The good news is that the product arrived. Nosotros specifically ordered one after the showtime moving ridge of reviews, to emulate the experience of a buyer who read one of those reviews and wanted to make a purchase.
To go on this simple, so we tin get into the actual review, we bought the monitor at the stop of July and put down a $100 reservation with Eve claiming a shipping appointment of September 2022. They requested the remaining payment in the middle of Baronial, challenge the product was "almost ready to ship."
That didn't actually occur until October 4, a month and a half later, and it ended upwardly arriving at its destination on October 12. At present, that'south probably not a huge issue. We bought information technology knowing full well it wouldn't ship until September, and it took a few extra weeks to arrive, and then a short filibuster. For those of you buying abroad however, on top of paying $800 for the monitor and stand up, the only shipping option was $184 for supposedly "express" aircraft.
Nosotros wouldn't advice buying it this way when basically every other monitor we could but buy from a local store for a fraction of the shipping toll. That was less than ideal, just for at present, allow'southward shift into a look at the actual hardware Eve are offer.
Design and Grade Cistron
The Eve Spectrum 4K is a 27-inch 4K 144Hz gaming monitor with all the usual features. It supports adaptive sync variable refresh rates, it has 1ms rated response times through the use of an LG IPS panel, and it has "HDR600" rating with up to 750 nits of brightness.
The big selling point here used to be HDMI 2.1, although in 2022 that's not particularly special as lots of 4K monitors include the feature. Eve also claims the brandish was crowd developed by 4053 members of their community, so it'll exist interesting to run across whether that's made a deviation in the final production.
We paid $800 for the Spectrum 4K but the price has since increased to $900 for new orders shipping adjacent yr. The $900 is split into $800 for the monitor and $100 for the stand, so if yous don't want a stand (eg. for VESA mounting) you lot tin salve yourself that money.
The pattern of the Spectrum is pretty overnice and while the stand up is pricey, information technology'due south quite an elegant product.
The base and pillar are both made from metallic with a pleasing grey finish, and the range of height adjustment is excellent in addition to pivot and tilt support.
Fifty-fifty though the stand up is thin and the base is non particularly large, information technology'due south sturdy overall and feels well congenital. I like the blueprint of the display itself, slim bezels, no unnecessary gamer style junk, no RGB LEDs. Overall this would be upwards there amid my favorite gaming monitor designs.
The slim department on the rear houses all of the ports, including one DisplayPort 1.iv with DSC and two HDMI 2.one ports. The improver of HDMI 2.1 is critical on a 4K 144Hz monitor as you'd be limited to merely 60Hz without it, and these are total 48Gbps ports.
Then in that location's also a USB-C input, which supports DP Alt mode and 100W of power delivery which is peachy for single-cable use with laptops. Several USB outputs are besides included along with an audio jack. Pretty good range of ports all up.
As for the on-screen display, nosotros get an piece of cake to operate directional toggle on the rear, although the interface itself is basic and surprisingly low resolution on a native 4K panel.
The range of included features is decent, it does take crosshair back up which about other monitors also take, plus the neat inclusion of integer scaling which tin improve clarity when upscaling 1080p to 4K. I wouldn't say the feature set is amazing, equally competitors like Gigabyte offer KVM switches which you lot don't become here.
Display Functioning
Looking at response fourth dimension performance, the Spectrum is interesting in that it provides a couple of overdrive settings in addition to user customizable overdrive through a slider. I like this setup a lot equally yous can really fine tune the settings, so let'south encounter how it performs.
Overdrive off functioning is fairly typical of LG's Nano IPS panels with a 9ms average response time and no overshoot. This mode is actually decently usable but we tin can improve performance by using a higher mode.
Adjacent up the chain is the Normal mode which appears to be the most balanced between response times and overshoot. There is a minor corporeality of overshoot detected, by and large in close together transitions, which in practice isn't noticeable while gaming. The average response has improved to a very solid 5ms average, which is what Eve advertises as the panels "typical" response. Cumulative deviation is likewise ameliorate than in the prior mode.
The High mode is your typical besides-fast manner that's designed to annunciate a faster response time than the LCD console can actually achieve. While the response time average is improve than the Normal mode, overshoot is significant and noticeable, leading to changed ghosting trails. Cumulative deviation is worse than the Normal mode, and then we've gone backwards when weighing upwards the residual between speed and overshoot.
Beyond this you can control overdrive via the user customizable slider, which allows values between 0 and 63. All the same I establish that a significant portion of the range is useless with quite a high level of overshoot. So I'll cut to the chase. When optimizing for the lowest cumulative deviation, I institute a value of approximately 15 to give the all-time experience at 144Hz.
This setting is slightly slower than the Normal mode, but to a negligible degree really, simply has a lower amount of overshoot. This is what I'd use for high refresh rate gaming, although the Normal style is besides pretty solid if y'all don't want to mess around.
As for adaptive sync gaming beyond the refresh range, Eve claims the monitor has variable overdrive, although I don't come across any evidence of this in exercise. They might exist incorrectly using the term to mean the user customizable overdrive setting, which is different to actual variable overdrive, where the monitor automatically adjusts its overdrive settings depending on the refresh charge per unit for the all-time experience.
The basics are that using a user setting of 15 for overdrive causes a bit too much changed ghosting at 60Hz. Afterward careful examination of a range of overdrive options, I ended up settling on a user setting of x for the best experience across the refresh range. This way is a picayune slower at 144Hz at a vi.55ms response time boilerplate, merely notwithstanding packs great performance with a express amount of overshoot at 60Hz, and everything in betwixt those refresh rates. Using this way provides what I'd describe equally a unmarried overdrive mode experience, even if it technically doesn't employ variable overdrive.
Compared to other monitors, the Eve Spectrum is decent at its maximum 144Hz refresh rate. Response times are in the ballpark of other IPS monitors, while retaining a low level of inverse ghosting. I was able to tune the monitor using the user adjustable overdrive to be slightly better than LG's 27GN950 also, which uses a like console.
On boilerplate across the refresh range, the Spectrum and 27GN950 are virtually identical. While it's nice to get all that user customizable overdrive controls to get the best out of the brandish, it seems LG is already doing that for you lot with their offering, so this doesn't give Eve a big advantage on boilerplate. Functioning again is solid and well balanced, though a monitor like the Gigabyte M28U isn't all that different if we're existence honest, providing fast response times at the cost of overshoot.
And that's seen further when looking at cumulative departure, which shows the balance between response times and overshoot. The Gigabyte M28U performs well, amid the all-time for an IPS monitor. The 27GN950 and Eve Spectrum are slightly backside, although really all these monitors evangelize a very like feel on average. The performance is right where I'd want it to be for a modernistic IPS gaming monitor, which is a issue betwixt 500 and 600 in this metric.
At 120Hz the Spectrum is a mid-table performer, delivering decent results for panel gamers looking at that 4K 120Hz experience over HDMI 2.1. Then at 60Hz the Spectrum is over again, pretty typical in terms of its operation with no notable issues. It'southward slightly slower than the 27GN950 but not to the degree where you should complain, every bit basically those two monitors deliver the same operation.
Input lag is a non-issue with the Spectrum, providing less than 1ms of processing delay and mid-tier results all up. The chief limiting factor for input latency is the refresh rate, every bit 144Hz is noticeably slower than 240Hz or higher monitors in terms of lag and smoothness. At this sort of cost indicate you can toss up between 4K 144Hz or 1440p 240Hz, so if you play a lot of competitive titles the faster refresh charge per unit may be of interest to you.
So we get to ability consumption. Unsurprisingly the 27GN950 and ES07D03 are basically identical for power consumption when calibrated to the same brightness output. Both use the aforementioned panel, so I wouldn't expect anything dissimilar.
The Eve Spectrum supports backlight strobing, and it's a really great implementation, specially for this sort of panel. The built in presets have minimal strobe crosstalk or double images, leading to noticeably improved clarity compared to running without strobing, and not that many artefacts aside from a slight trail. You get the best image quality with the "short" pulse width, but the lowest effulgence, although even the "long" pulse width with a high level of brightness is all the same decent. This can be further tweaked using either the congenital in user controls in the OSD, or the BlurBusters Strobe Utility, for the optimal results.
This level of flexibility and command over the strobing mode is what other companies should be aiming for with their modes, because information technology always delivers the all-time results. The Eve Spectrum ends up with great strobing, and a large degree of flexibility, including the ability to use strobing with any refresh rate, such every bit 60Hz which is not possible with many other monitors.
However in that location are some drawbacks. Overall strobe quality isn't perfect due to the persistent event with KSF backlight LCDs, which is the slow crimson phosphor. This causes red trails when using backlight strobing, and this tin be quite noticeable fifty-fifty when the level of strobe crosstalk is low. For that reason you may not want to use it. Eve as well doesn't back up using backlight strobing and adaptive sync simultaneously, which is increasing in popularity with other brands.
Colour Performance
Colour Infinite: Eve Spectrum 4K - D65-P3
Moving now into color performance and the Eve Spectrum is a typical wide gamut monitor using an LG console. Information technology has 97% DCI-P3 coverage, which is very wide and well suited to work in that color space. Across that, back up for Adobe RGB is more than limited and overall Rec. 2022 coverage is 71%, which is an average effect by modern monitor standards.
Default Colour Operation
Default manufacturing plant calibration was pretty good with my unit, at least for greyscale performance. The CCT curve is impressively apartment and balanced, leading to perfect tone out of the box. The gamma performance isn't perfect, only decent enough and that leads to proficient deltaE results. Nonetheless the default experience using the Spectrum is its wide gamut mode, despite the majority of SDR content only using or requiring sRGB/Rec. 709. What this means is by default, the console is oversaturated.
So what we encounter when compared to other monitors is that the Eve is quite boilerplate in ColorChecker performance, just pretty decent for grayscale performance, at least in its default land.
Notwithstanding operation can exist improved notably by switching the monitor over to its sRGB style. Greyscale deltaEs drop in this configuration to below i.0 in deltaE 2000, and just 3.0 in dEITP, which is very strong, despite some inconsistencies with the gamma curve. Color operation is likewise very strong, as the colour gamut is being managed perfectly and this leads to no oversaturation. All up this sRGB way is a lot better than average and very usable without any farther calibration.
Calibrated Colour Performance
You lot'll also get peachy results for P3 when the monitor is set to its P3 mode, with deltaE functioning that'due south very similar to the sRGB manner. This means there's a stiff level of hardware calibration for both of the colour spaces the display supports, and calibration can just improve things slightly. I would like to see the sRGB mode unlock white residue controls, they are locked which isn't a huge deal just all the same unnecessary, just outside of that I'k very happy with the calibration existence provided here – so long every bit you switch it into the sRGB fashion for everyday use.
Effulgence is decent, offering 450 nits in its SDR mode, which is merely beaten by true HDR panels like the PG32UQX. This level of effulgence is like to the LG 27GN950, but a lot better than the Gigabyte M28U. Minimum brightness isn't amazing though, at 76 nits, which should be fine for nigh users but isn't as low as other monitors tin go.
Native contrast ratio is solid, at 1160:one with my unit. The 4K version of LG'southward Nano IPS panel doesn't suffer from the same contrast problems as with the 1440p versions, and the Eve Spectrum was even a little improve than my 27GN950 sample from LG. Unfortunately though, contrast is poor in general, due to existence an IPS panel. VA displays have more than twice the level of dissimilarity, which makes them more than suited to dark content or playing games in the night.
Viewing angles and uniformity were both good, and LG panels tend to have in a higher place boilerplate uniformity which is smashing for content cosmos. The main part of the screen was very uniform with my unit, and in that location was merely a pocket-size amount of falloff in the upper correct corner. I should note that uniformity is unit dependent, and what you receive may be dissimilar.
HDR Performance
As for HDR functioning, the Eve Spectrum is a semi-HDR monitor. While it does pack respectable effulgence capabilities, a wide color gamut and some course of local dimming to better the contrast ratio, it fundamentally lacks the hardware for truthful HDR visuals. The monitor only has sixteen edge lit dimming zones, which leads to a lot of blooming and haloing when viewing HDR content. In a lot of cases, all dimming zones are illuminated, which prevents the brandish from actually showing bright and dark areas close together.
To quickly run through HDR functioning, the maximum brightness the console can achieve is solid, at around the 700 nit marking whether sustained…. every bit a wink… or at small window sizes. In fact across various window sizes the effulgence never dips beneath 600 nits, whether sustained or peak, which leads to solid brightness, especially at normal monitor viewing distances.
Where the Spectrum suffers is in contrast. The absolute best contrast ratio I could achieve was 20,000:1, which was between a total black window and a full white window, inappreciably realistic. Within a single frame, the best I could accomplished dropped to only 11,600:1, which is well curt of the sorts of contrast ratios HDR is recommended for.
And then in the worst cases, when dark and bright objects are on screen side by side, the Spectrum reverts to its native dissimilarity ratio, so in those situations it's not capable of HDR-level performance at all. Y'all can get a better-than-SDR feel some of the time, merely about of the time the experience is quite poor, and so I wouldn't buy this for its HDR specs or capabilities.
What Nosotros Learned
At that place'southward a lot to like from the Eve Spectrum 4K from a operation perspective, while it'southward less stellar on the availability and pricing forepart. Outside of HDR, where the Spectrum is not very good, this monitor performs very well. Response times are decent, and right where you'd want them to exist for a mod IPS gaming monitor, plus nosotros become very expert backlight strobing and an important feature in HDMI 2.one.
This isn't as revolutionary as it once was now that we take more competition in the 4K 144Hz monitor space, simply the Spectrum ticks all the boxes for movement performance and information technology'due south dandy to game on.
Color functioning is what I liked the most. Factory calibration in the sRGB mode is very skilful, and it's clear Eve spent time ensuring each unit passes some sort of factory scale process. It's also well suited to content cosmos in the P3 mode, which has decent hardware scale as well. Throw in good uniformity and dissimilarity, and there's a great amount of versatility to use the monitor for gaming and productivity work, which y'all'd desire out of a 4K monitor.
While performance is stiff and the Spectrum packs a modern feature set, I don't call up the whole "crowd developed" affair has added much to the display. In that location's a few things they might non take included otherwise – like integer scaling support – but it shouldn't take an online forum for a monitor maker to realize they should factory calibrate their high-terminate brandish, or to optimize the backlight strobing. That attribute is a fleck gimmicky considering several other monitors do just also here.
Equally for its directly competitors, with Eve charging $900 for this display including the stand, information technology competes at the loftier-end of the 4K 144Hz market with products like LG's 27GP950, the newer version of the 27GN950. The Spectrum 4K is a better version of the 27GN950 with better functioning.
However I wouldn't automatically recommend the Spectrum when products like Gigabyte'south M28U exist. For $650, the Gigabyte comes pretty shut to the Spectrum'south functioning – including strong response times, HDMI 2.1 and great manufacturing plant calibration, but it's a lot cheaper. The Spectrum, like the 27GP950, is not a great value pick and yous're ending up paying a big premium for a few extras. This display might be the way to go if you demand the backlight strobing, or integer scaling, but for everyone else, the latest generation of 28-inch 4K monitors offers amend bang for buck.
As for the release strategy, Eve was taking pre-orders for this display in mid-2020 with an expected release appointment for the end of that year. Back so the monitor was supposed to exist $700 with the stand included, and the company heavily touted offering the first 4K gaming monitor with HDMI 2.i. Just that was then, and surely it'd have been an excellent product in that marketplace and timing, which would explicate why and so many people jumped on board to pre-social club.
But delaying the product well into 2022 saw Eve lose its competitive reward. New 4K monitors striking the market earlier this year delivering about of what Eve promised, at like or better cost points.
Nosotros ever recommend against pre-ordering and here's one prime example of why y'all shouldn't and why a company's unabridged launch strategy shouldn't be based effectually information technology. The Spectrum 4K is a good monitor, but it's zero overly special in today'southward market.
