Performance

The brightness of the display when measured at 100% brightness in Standard mode was 259.44cd/m2, and it seems that the monitor was running at 80% brightness by default, which measures in at 212.7cd/m2.

Acer Predator CG437K S Review – Screen uniformity test

We ran the screen uniformity test in a 3×3 grid format since it’s the standard 16:9 aspect ratio. 4 out of 9 areas here passed the nominal tolerance whereas the remaining exceeded it. Interestingly, the ones that exceeded are all four corners, which are noticeably dimmer than everywhere else. The center area isn’t counted as that is the area used for reference. For gaming, it should still look great and most people wouldn’t be able to tell the difference.

Colour Accuracy

  Standard Standard mode, calibration with DisplayCAL
Whitepoint 6493K 6487K
Average ΔE*00 0.39 0.31
Maximum ΔE*00 1.03 1.25

By default, the Acer Predator CG437K S has good colour accuracy. After calibrating it using SpyderX and DisplayCAL, the improvements were minor, but at least it’s there. The maximum delta-E figure did see an increase but it did lower the average from a good score to an even better one. This would be great if you want to see visuals as they are meant to be but it’s a bit hard to recommend this for creative work due to the uneven brightness from the previous section.

Gamut

Gamut Standard Standard mode, calibration with DisplayCAL
sRGB Coverage 99.9% 99.9%
Volume 138.8% 139%
Adobe RGB Coverage 85.7% 85.8%
Volume 95.6% 95.7%
DCI-P3 Coverage 94.5% 94.5%
Volume 98.3% 98.4%

For the gamut coverage and volume, it doesn’t seem to differ much before and after calibration either. Overall with 99% sRGB, 86% Adobe RGB, and 94% DCI-P3, it does offer a relatively wide gamut coverage and should be suitable enough for most content creators out there unless you have a specific need for higher Adobe RGB or DCI-P3.

The Good

Acer Predator CG437K S Review - The monitor itself

Acer Predator CG437K S Review – The monitor itself

For the most part, the Acer Predator CG437K S is essentially the same as its predecessor, the CG437K P. The biggest difference is the upgrade to HDMI 2.1, which is great for both PC and console gaming as it allows you to enjoy up to 4K 144Hz, or even the full 4K 120Hz experience with HDR on the PS5 and Xbox Series X.

The next thing I like about this is the sheer size. It’s basically a TV but you don’t miss out on typical features found on gaming monitors. Sure, there are TVs out there that can support 120Hz refresh rate but this one has faster response time, G-SYNC support, a USB hub built-in, and more. You’d be hard-pressed to find a TV that can do these things at this price.

Speaking of the USB hub, it deserves a mention of its own. After all, you have a number of upstream and downstream ports along with a USB-C with 30W charging and DisplayPort capabilities. This is especially useful for a cleaner setup or if you’re transitioning between a laptop and a desktop while using the monitor as you don’t have to change to another keyboard / mouse.

Acer Predator CG437K S Review – RGB LED strips

As the design is unchanged from its predecessor, it retains one important design element; the stand has a platform for you to place your gamepads on. Unsurprisingly, the monitor takes up a lot of space given its sheer size but you don’t have to sacrifice all that space. This smart design element along with the headroom between the monitor and the surface its placed on gives you plenty of room to place your things. Fair warning, you won’t be able to fit your PS5 or Xbox Series X console here.

Lastly is the inclusion of the remote control. Since it’s a TV replacement, no one is going to use it in close proximity. This means accessing the OSD and navigation buttons will be difficult. The remote control, which is the same as its predecessor, will let you access all the settings with ease.

The Bad

As the design remains unchanged from its predecessor, a couple of drawbacks have made its way back here. The first is the lack of a tilt, swivel, or height adjustment. The latter is still forgivable as the sheer size of it would make it pointless but having the ability to tilt or swivel, even slightly, would be great. It’s likely hard to achieve due to the weight of the monitor.

The second is the RGB lighting implementation as it’s not built-in. It basically comes with RGB light strips which you are to use to stick to the rear of the monitor. Of course, you have the choice of placing it elsewhere instead but either way, it results in a rather messy, confusing implementation of RGB lighting.

While I did praise the connectivity options available here, particularly the USB hub, it would have been great if the power increased from 30W to 90W or at least 65W. That way, the more power-efficient laptops can be used with it without the need for a charger. 30W is only usable to charge your smartphones, some tablets, and other smaller gadgets.

Acer Predator CG437K S Verdict

Acer Predator CG437K S Review

The Acer Predator CG437K S is a formidable gaming monitor for those looking at larger options. The move towards HDMI 2.1 makes it suitable for next gen gaming consoles currently in the market, namely the PS5 and Xbox Series X. If you don’t have the need to game at anything higher than 4K 60Hz, you might be better off getting the predecessor as it’s likely more affordable now.

At the end of our Acer Predator CG437K S review, I award this gaming monitor with our Silver Pokdeward.
