XG27ACS - Impressions after opening and setup.

ChrisOctober 26, 2025

Day 1 Impression: On-Sale $234 shipped. 27qhd highHZ, can't complain. nice packaging and accessories. Love the stand - matches my RogStrix G513QY laptop nicely, very sturdy. Purchased to mount on a mobile desk with the 15inch laptop screen removed. The screen itself is rather light, easy vesa mounting if needed. usb-c to usb-c display is a bonus. The Display is... "As expected" for the price and NAME BRAND. except.... The anti-glare "FOG" almost looks like backlight bleeding at angles, definitely a tradeoff for no major glare in well-lit areas. My Display showed Zero dead pixels, 1 small spot (1inch) of backlight bleed on the bottom horizontal run, but I can live with it... for the price. Menu/Picture settings are easy to navigate, and the QHD is beautiful, even with standard hdmi 60hz. Very Happy purchase for a budget laptop extension/extra display. If it works like this for 3-5+ years no troubles, I'll say it's a good purchase. Time will tell. ***In the picture shown, the blue areas are the Anti-Glare FOG, noticeable in dark scenes when in a dark room or when viewing at angles. It is not truly noticeable during day/lights-on. The Green area is the small Backlight Bleed (Not noticeable during day or other than black screen) Second photo is during the day on black screen test, slight "Angle-AntiGlare Fog" nothing harsh. For the SALE price, I would repeat the purchase, no real complaints, hope it holds up. Read more

Excellent monitor. You get what you pay for!

JMJanuary 7, 2025

I need to start by saying that I just recently purchased a different, cheaper 34in 2k monitor from an off brand here on Amazon, and I was so appalled with it after a day of trying to get the colors to look correct, and the HDR to work, and a dozen other issues, that I wrote a multi paragraph review expressing my discontent and returned the monitor. So that brings us to the Asus Rog 34in 2k OLED, which I bought as a replacement. Yes, this monitor is very nearly 3 times the price of the one I just returned.... But the old adage that you get what you pay for is never more obviously apparent than when dealing with monitors, as I've just learned. The difference in quality is staggering. I have been blown away by this monitor. Deep contrast, absolutely no color or gradient banding, seamless HDR support without any fuss (literally just enable HDR in windows display settings and done), the colors are fantastic, the OSD menu is the best I've used on a monitor (I love the little joystick button on the bottom for menu navigation), the 180hz refresh rate still being available at full resolution AND HDR enabled was actually surprising (usually you can have HDR or the max refresh rate, not usually both at the same time)... Also my AES mount fit right into the recessed space on the back (other monitors require standoff spacers because the recessed area isn't large enough) This monitor looks amazing, and you won't be disappointed. If you're looking at cheaper monitors, especially off brands to save money, just stop. I just learned my lesson, so I'll pass this wisdom on to you. Cheap out somewhere else. The monitor is not the place to do it. As far as criticism, not much to be honest. I guess if I was splitting hairs, the cable guard removable panel on the back is a little annoying. There's a cable guard panel that pops off on the back with a small cutout to funnel the wires through at the top of it. (It's a half circle cutout at the edge of the panel, not a hole) While it doesn't hurt anything, and does keep the wires bundled together, you have to bend the cables at an uncomfortablly tight angle to get them to fish through the cutout. And, for those who are unaware, bending DP and HDMI cables is a no no. It would have been nicer if that cutout was placed lower on the removable panel so the cables didn't have to bend as much to make it out. But if you don't want to chance it, just leave the cable guard panel off. Either way it isn't a major deal, just something I kind of mumbled some words about as I was setting it up. But that's really it as far as the negative goes. The resolution is amazing. HDR is extremely good. Refresh rate paired with Nvidia gsync is flawless. The OLED contrast is game changing for cyberpunk 2077. It's curve angle is spot on. I have it wall mounted with a fairly narrow desk, so I was worried I'd be sitting too close (about 22in measured from my eyes to the screen), but it's actually very comfortable to use the full width of the monitor. I did roll my chair back to where I was 32in away to see if people with a deeper desk would have issues but it feels comfortable at that range too. I rarely leave positive reviews (about the only time I'll leave a review is when a product really ticks me off, and those aren't typically positive reviews) But for this, I felt it was necessary to share my thoughts. Asus deserves it. Especially since I'm not easily impressed when it comes to gaming PC hardware and devices. I really was genuinely impressed with it. And I'm not just saying that because it came with some fancy RoG Strix stickers lol Read more

Excellent panel and packed with features.

bmapsDecember 2, 2025

Excellent picture overall, with nice brightness leaving a very nice HDR-kinda impression (no local dimming tho). It's the best panel I've used outside of OLED with very fast response times, high refresh, true G-Sync with variable overdrive etc. Lots of features for a 'budget' monitor. The stand is also very sturdy and the silly phone holder is surprisingly useful. Smooth up/down operation and tilt/rotate. Overall build quality Is the mid to higher-tier of ASUS which is nice for the price. Shipped in a large box with thick protective polystyrene sandwiching the panel, and the included cable bag is a nice touch. My biggest gripes are the poor viewing angles, lower contrast ratio, and IPS glow in dark rooms unless perfectly head on. Also it's not really HDR due to no local dimming but I will say with HDR enabled it looks fantastic. Honestly, if you want to play games in a dark room id go with a good VA or OLED panel instead, but this is a fantastic monitor overall and at a great price even before sales. Read more
