Upgraded to this beasty from a 27” 1440p RoG Swift from a few years ago. It was dual-purpose upgrade: increased horizontal desktop real estate for coding IDE work and more immersive gaming. Delivery from Amazon was brisk, and the box was in perfect order. This monitor is packed very well, and the box wasn’t as huge as I expected. Here’s a breakdown of the "pros" and "cons": + Received with no dead pixels or any other obvious defects. + Comes assembled and ready to use AND is calibrated from the factory – just remove the plastic connect and play! + The factory calibrated settings look as good as what I was able to achieve on my ROG Swift after a lot of careful research and tweaking. + Overall solid and attractive hardware design, with a very sturdy base which allows you to clamp the monitor down to the back of your desk. + The image quality is a bit better than on the aforementioned 27” RoG Swift. That 10-bit wide color gamut really makes things pop. + The HDR implementation is actually decent. You do get most of the desired effect when streaming HDR videos and playing HDR-enabled games. The best-in-class 550 nit brightness and the wide color gamut make the standard baseline DisplayHDR 400 implementation better than on the previous generations of such monitors. I mean, it’s not even close to my LG OLED TV, but not bad! I wasn’t expecting much and was pleasantly surprised. Played Doom Eternal and Gears 5 and they both felt enhanced by the HDR. + The G-Sync implementation works perfectly, with not even a hint of screen tearing anywhere. + TWO (x2) DisplayPort 1.4 inputs! This is actually the feature than made this monitor standout from the competition for me. I wanted both my gaming and work boxes connected via DP (for a change) and this monitor delivered! + It really is a dual-monitor setup replacer and is great for codding IDE use, with lots of horizontal desktop real estate. + No issues with the built-in USB hub. + No “Acer” logo anywhere; just the kewler “Predator”! + Elegant and conservative aesthetic, with no LED lights or brightly colored plastic anywhere. This might be a con for some! + Easy height and angle adjustments that stay put. and as far as the "cons"... - The base is a bit too deep if you’re like me and have a narrow desk. One of the legs was interfering with my mouse pad. My solution was to move the monitor further back, which left the back of the base extruding off the desk. I then clamped it down, so that it doesn’t try to move further off the desk. Worked out ok, but it is bit annoying. - Backlight bleed. I know that it’s an issue inherent to all IPS panels - certainly all the ones I’ve ever owned. However, this monitor has it a bit more pronounced than my old RoG Swift. On the bright side (pun?), it’s only really noticeable when the screen is all black and doesn’t particularly bother me. - This is a 10-bit panel but only up to 144 Hz refresh rate! If you set your refresh rate any higher, it becomes an 8-bit panel. Not a big deal to me, since 144 Hz is plenty for my needs. I prefer the 10-bit gamut to higher refresh rates. - The input positioning and access is atrocious! Hooking everything up too way longer than it should, with me basically having to feel my way around like a blind person. My ROG Swift had the same issue, but it’s even worse here. Luckily, once everything is hooked up, you no longer have to worry about it, and it does make the cabling less conspicuous. - The OSD is pretty “basic bitch” and switching inputs takes too many clicks. All these “cons” are minor, are not enough to knock off a star from the rating and are grossly outweighed by the positive aspects. By the way, a lot of people seem to be confused as far how to set things up in order to consume HDR content. You have to select the HDR Color Mode in the monitor’s OSD and then also enable “Use HDR” under Windows 10’s Display Settings. Then, to get any benefit from it, you have view HDR content, such as HDR enhanced streaming videos or games with HDR support built in and turned on (in the games’ options). Windows 10’s HDR integration used to be pretty crappy, but they seem to have worked out the issues and I’ve had zero problems. Overall, outside of some nitpicks, this is a great monitor and I do recommend it for either work or games. I agree with another reviewer that this is the best 34” UWQHD monitor under $1000.

I am new to this product. The only bad thing is the message that pops up every hour or so. Other than that I have been very pleased

honestly just look some where else or wait. oled technology is just so bad at the moment. especially for PCs and gaming. these monitors are VERY dark and the only acceptable way to use them is at 100% brightness with HDR and u can literally feel the heat coming off of it. the asus models come with better cooling then these generic acer models but asus does not offer a curved panel with their qd oleds. Also my biggest con is the base. the monitor sticks off the arm around 6 inches or so and the feet are a near 90 degree angle V shape. i have a custom built desk thats deeper than most u will buy and its about 2 inches from the wall. with my monitor touching the wall the feet stick out so far my mouse pad hangs off the front of the desk. very VERY poor design. the options menus are not that great. u cant change settings in 99% of modes. very locked down IMO. gettin hdr to work properly in windows is a disaster so dont expect smooth sailing with that. only browsers that will support it properly are chrome and edge as far as video playback in youtube. even typing this review on amazon the all white background is so dull it looks beige or light grey. peak brightness or anything white is only available on a tiny portion of the screen. color accuracy out the of the box again is pretty bad took a lot of tweaking in nvidia to make it look acceptable. my previous monitor is an rog strix xg32vc 32in 1440p hdr10 400nit and it was a good bit brighter than this which claims its 1000nit. absolute lie. maybe a single pixel. over all i am very disappointed in this purchase and an appropriate value for this would be no more that maybe 450-500 max. when u can get a 48in lg oled for less than the cost of these monitors. they are just NOT good at all. i feel as if manufactures are scraping by and shoving mediocre garbage at us to try and make a sale and run off with our money. there is absolutely zero value here. unless u are watching 99% dark content there is no benefit. Had to update to 1 star. after purchasing numerous monitor stands to attempt to get this to fit properly on an oversized desk all of amazons options are just cheap temu like garbage. i want a premium product and im just not getting it here.

I like getting good value for my money without spending on features with diminishing returns, and I feel this monitor fits the bill nicely. It includes the features that matter most while skipping some less important but still useful ones. For example, the stand offers decent adjustments—good enough for my needs—but it’s not the best, which likely helps keep the cost down. I really like the monitor’s design. It doesn’t have that typical 'gaming' look; instead, it’s sleek and high-end, which I appreciate. That said, I’d love a few more options in the menu, like the ability to turn off the joystick LED. It’s located under the monitor, so it’s not a huge issue, but it’d be nice to have control over it. Another minor annoyance is the warning message about 'turning off the LED' that pops up. They should add a way to adjust its timing. Fortunately, these are things that could be addressed in a software update. If that happens, I’d happily bump this review to five stars. Overall, I’m very satisfied with the monitor—the picture quality is fantastic for both gaming and watching movies.
