HDR is as good as the LG27UL, UN and UK series that is 400 certified
Finally I found a great monitor with no backlight bleeding. It has some ips glow but that is ok, as the black levels in this monitor is the best I have seen in an ips monitor so far.Second of all, people are complaining about HDR being washed out for 2 reasons 1- They are using HDR on non supported HDR games 2- Or they are playing a game that has terrible HDR implementation to begin with, and a good example for such a game is Red Dead redemption 2 which looks terrible and washed out when HDR is turned on(this is even for the best HDR TVs as it is a game issue and not a monitor or a TV issue), but you can still fix this issue by tinkering with your PS4’s HDR calibration settings. Games that I have tried on this monitor and look great with HDR for PS4 pro are(Spider man, God of war, Ghost of Tsushima, Horizon zero of Dawn).Most importantly I do not understand why is this not vesa hdr certified while LG UK, UN and UL series are. For one, the LG monitors in the series I have listed and that have the “400” hdr certification, do not even exceed 350 nits(Their peak brightness is 350 nits, just as high as this Asus monitor) which is funny because both the Asus TUF Gaming VG289Q and the LG 27UK, UN and UL series are all 350 nits max, but for some reason the LG was able to acquire a Vesa 400 certification for its HDR, but the Asus TUF Gaming VG289Q, which has the same amount of nits(350), did not acquire this certification.All in all this is a great monitor that has the best black levels for an IPS monitor and it is of better quality than the more expensive LG27UK, Ul and UN series. Its black levels are very impressive and makes any game that much more atmospheric and immersive, regardless of the resolution. For example, Cyberpunk on PC, set at 1080p, actually looks great on this monitor due to the black levels (without HDR).-The Cons, What are they?1-The Buttons and the Display options are kinda terrible and inaccessible/nonintuitive.2-No volume buttons or wheel, so you actually have to go into the OSD(on screen display options) in order to get into the volume section to turn your volume up or down.3- It does not come with an HDMI cable and only comes with a Display Port cable.4- Terrible wire connection locations(vertically placed in the back rather than horizontally, which LG monitors win in this department)5- And lastly there is no quick buttons for input changes. You still have to go into the menu in order to change your input from HDMI 1 to HDMI 2 to Display Port and vice versa.So good thing non of the cons have to do anything with the actual image quality because this monitor performs very well in that department. I feel they skimped on these technical issues in order to give you an Amazing display for this price, so the shortcuts that were made to offer such an amazing picture for this price, are mostly the cons I have listed, and It did not come at the expense of image quality which is great.Of course many people would add 60hertz as a “con” but for gamers who are not planning to play games higher than 60fps, then there is no reason to consider this a con. It is only a con for people who care more about performance in multiplayer games, than about image quality. And no, the new consoles will not take advantage of monitors with higher refresh rates in triple A tittles and only a few games will even run at 4k 120 hertz on the xbox series x or the PS5. It is a gimmick that you should not base your monitor shopping decision on. I mean the PS5 box states “8k”…does that mean that games will run at 8k on PS5 and that you should go out and now buy an 8k TV to “future proof” yourself? lol of course not. Gimmick advertising is a thing children.

GOOD monitor
This ROG monitor is a fantastic all-rounder that just nails all the key experiences.Its 4K 160Hz Fast IPS screen is sharp and incredibly smooth, with vibrant colors and brightness that’s the real deal—not over-advertised like some other “HDR400” monitors with a peak of 350…Add in the convenience of a USB-C port and a solid three-year warranty, and it’s a purchase you really won’t regret.

The most beautiful anything has ever looked, but an annoying flicker.
For context, in my picture, the 4k monitor is the one on the bottom right. OS is scaled up to 200%, and you can still see how big the variance is compared to the 1080p settings of the other monitors.This monitor is pretty spectacular. With the setup I have, I’m running some absolutely gorgeous scenes with godrays, RTX, and steady frames. Everything is crisp and fluid. The monitor has picture quality like nothing I’ve had before. I know IPS isn’t the end-all-be-all, and PC HDR isn’t that good apparently, but this is worlds above my previous displays. It picks up on G-Sync. Windows loves it. All around a pretty great experience!But, there is a small problem. This persistent flicker.It’s purely video signal. The monitor never loses power. All of the systems are cabled up properly, and I’ve swapped my current cables and ports a few times, to no success.Sometimes it’ll go hours and hour without a single flicker. Other times it’ll start strobing at me to the point I have to turn it off – which usually calms it down for awhile.I have done all of the driver updates, removals, and reinstalls half a dozen times. I’ve removea nd readded my display adapters to try and get things running. Even run a recovery on the operating system, which I was reluctant to do.Did you see that typo I left up in the previous paragraph? The monitor flickered on me just now, and I kept typing through it. So, again, not a huge problem. One I’m adapting to, but kind of something you don’t want.I imagine I *will* solve it, in time. I’m going to invest in some highly spec-ed cables for the entire setup. I’m going to test my success with different ports, and really run it through the gamut of testing. To narrow down exactly what’s causing it, and fix it for good – or maybe RMA it if absolutely necessary. Probably not though. This thing is huge, cumbersome, and likely pretty fragile. So if I can avoid that, I want to.Now, I do this for a living. So I’m fine with this level of effort. A normal user? Probably not. And a gamer who might be competing in ranked and throw an entire round over a screen blacking out for headshots? Yeah, this would probably be an instantaneous refund. (That did actually happen to me once. Was sad, but not completely rage inducing.)So, consider your use case. Look at other reviews. If I’m the odd one out, that means this monitor is super reliable, and you should see if it fits your needs. If you see reviews like mine, and you need ultra-reliability, I’d consider maybe finding something a little less hi-fidelity that really rocks the house.4K is a luxury. We still have issues maxing games on 4K Raytracing with the best components money can buy. Don’t feel the need to rush.

If you’re playing single player titles or just playing for kicks with friends online this screen will meet your needs. The HDR isn’t absolutely eye-popping, but I don’t find it lacking by any means. I used windows HDR calibration app which I must say really brought it all up to par. I’ve got this hooked up to a 4090, g-sync enabled. The frame rates are butter. Absolute constant 60 fps.3D modeling and Photoshop have looked and worked great on this monitor. No complaints there. The 10-bit colour depth coming in with 1.02 billion colours, standard contrast ratio, and slightly above standard brightness all add to the experience.The stand is actually very nice. Great quality, and many angles of adjustment.I’ve been playing around with the idea of buying two more of these monitors for a triple monitor set-up. Absolutely love it.Highly recommend.

Overall good product. HDR in black background is acceptable. Cannot ask too much for edge-lit. Delivery is faster than expected.
