Screen Protection
ASUS OLED CARE PRO
New ASUS OLED Care Pro technology provides a full set of customizable monitor settings to protect the OLED panel and ensure longevity. Plus, it includes the new Neo Proximity Sensor that detects your distance from the monitor and transitions to a black image when you’re away to safeguard the panel from burn-in. All settings can be easily managed via DisplayWidget Center.
Neo Proximity Sensor
The built-in Neo Proximity Sensor precisely detects your distance from the monitor. When you step away, the monitor transitions to a black image to protect against panel burn-in, and instantly restores onscreen content when you return. Detection distance can be customized to suit personal preference, ensuring maximum convenience and protection.
Pixel cleaning
Recalibrates the screen when the monitor has been active for several hours?a process that takes just a few minutes and activates automatically when the monitor is turned off*.
* Do not unplug the power cord during this time as it will interrupt the pixel-cleaning process.
SCREEN MOVE
Pixel locations are slightly shifted periodically to help prevent burn-in, and users can choose between several movement levels.
Boundary detection
Dynamically detects the boundary of the black bars and reduces the brightness and also slightly shifts the pixel of the near borders.

Pros: – Beautiful picture, at all angles, no matter what
– 4k looks absolutely amazing on it
– silky smooth 240hz refresh rate (gonna need that 5090)
– amazing response time
– display port 2.1a uhbr 20 means the full 80gbps bandwidth and no display stream compression
– perfect size for gaming and the profile of the monitor is slim
– can vesa mount on an arm if desired
– the stand is robust, easy to assemble and doesn’t hog too much desk real estate
– really good monitor interface and controls, super easy to use
– offers many really good features and modes in the settings for customization (cinema is my favorite)
– tons of OLED protection/care features to ensure it doesn’t burn in and increases its lifespan
– power adapter built into the monitor so you don’t need a brick in-between your power cables, very nice if you want a clean setup
– logos look neat when lit up Cons: – brightness could be a bit better
– dp 2.1 cable is very short (if you want a longer cable, u will have to get a fiber optic) make sure to accommodate for the short cable, so your pc needs to be right next to the monitor otherwise.
– if not set correctly, the proximity sensor can turn off while using it. It also sometimes detected my desk mic and did not turn off when it was supposed to. Overall Review: I have never seen a monitor so beautiful, and coming from IPS and VA panels this is just gorgeous. Pictures and videos really do not do it a justice, you have to see it with your own eyes. I have waited a long time for an OLED monitor like this, many I’ve looked at in the past turned me away for various reasons. Ultrawide or too big, refresh rates were never great, panels were prone to burn in, display stream compression, lack of brightness, etc. Some of the OLED released last year started to cover most of these bases but this one does it all. You really don’t make any sacrifices with it, maaayybbeee the brightness could be better, but that’s about it. If you are a gamer and have always wanted an OLED but never made the switch, this is the time!!

Pros: Sharp details.
Great PPI Cons: Does get a little warm. Wish the power supply was external Overall Review: Enjoying this screen so far. Have it hooked to a macbook pro.

Pros: Great color accuracy
Crisp, sharp picture
High refresh rate
Crisp texts and fonts Cons: Pricey
Glossy screen reflections if you are in a bright room
A bit hard to clean. Recommend microfiber wipe and distilled water. Overall Review: Upgraded from a 4K IPS display and now I know what all the hype is about. Would recommend anyone go with OLED if you are buying a higher end GPU. Easy to setup. Tons of features like OLED Care to help reduce burn-in. Terrific color accuracy. Games look incredible and because of the PPI even text looks great which used to be one of the main complaints about OLEDs.
GilroyPro –
Pros: OLED, extra crisper 4K, 240hz Cons: Back navigation buttons could be placed better. Overall Review: This is currently my End Game monitor. OLED prestine picture quality with high 4K PPI and very smooth 240fps is you can drive that. Perfectly pairs with my RTX 5080, i9-14900ks, 96gb DDR5 RAM 7000mhz PC. More than enough to drive 4k at 240fps brute force on tons of games and/or DLSS multi frame generation if needed for more demanding games. Don’t have to depend on DSC anymore thanks to DP 2.1. Nothing wrong with it but a slightly less input latency and being able to use PnP properly is a plus. Definitely recommend.

Pros: This is end game, there is no question.
4k oled and 240hz are the key features here and 27 as well for great PPI (added pro that my desk can only fit up to 27 currently)
Coming from lg ultragear 1440p 240hz oled wasnt expecting much considering main difference is just resolution. But wow, everything just pops and the colors seem perfect out of the box (in cinema mode) Cons: Fps drop from 1440p sucks. Gonna need to upgrade my 4090 to make up for the dip in frames. Dlss helps but the fps leaves some to be desired. Gonna take a bit for 5090 stock to get sorted out Overall Review: If you have a 4090/5080 or above, just do it.

Pros: – 4k monitor Oled
– Amazing colors compared to my former monitor 2k ips display
– 240hz for high refresh rate
– Outstanding ppi count
– Excessive features to mess with
– Oled care and 3 year warranty Cons: – Expensive, but good upgrade
– Serial number cannot be registered on asus when recieved, may need to talk to support
– Nvidia overlay doesn’t register actual fps count in most games with monitor Overall Review: Great monitor if upgrading from lower resolution or coming from an ips user, definitely recommend

Pros: I am playing many different games. Everything, and I mean EVERYTHING looks amazing. I first started with D2 Resurrected, and I literally felt like i was looking through a window to hell. Getting back into Lost Ark, everything is simply amazing. The colors are incredibly vibrant and it has made gaming in all honesty, so so much more enjoyable. I also have on of my old monitors i am still using which i believe is 1440p and IPS panel, 144 hz and the difference is night and day. The sharpness and quality of image you get with this Asus monitor is honestly unbelievable and until you see it with your own eyes, you will not want to go back to anything else. Cons: I am trying to think of Cons but I really can’t think of anything. I am very cautious about burn in and it has a bunch of anti burn in things already pre set for you, and i have my display to turn off after 1 min. No cons from me. Overall Review: As the saying goes, you get what you pay for. If you are looking for quite possibly, the best display out there for 27 inch monitor currently, this is your choice and you will not be disappointed. It does have some RGB on the back of the monitor which I personally hate, but I don’t see it because it’s on the back of the monitor so I could care less.
If you’re coming from an IPS display or anything that is not OLED / QD-OLED and you have the money to spend or do not care about spending it, go with this. I will 100% guarantee that once you set it up as soon as you turn it on, you will have a big shih eating grin on ur face.

Pros: – 4k 240hz low ms in a small package, perfect for high fidelity gaming
– OLED is exceptional at delivering rich colors
– Build quality is high Cons: – The proximity sensor is gimmicky and unreliable, so I had to disable it
– Very expensive
– Came with 1 dead pixel Overall Review: – One of if not the best monitor to get if you’re gaming on a high end card such as a 4090, 5080, 5090
