The media could not be loaded. It’s an OLED so its gonna be good. I didn’t have any text fringing or eye strain even after 4 hours straight use. Picture quality is great. Brightness is good enough for me.Im impressed by the colors on it. It doesn’t get any better in this price.Now the cons are that the upper side of the panel is very thin so if I want to tilt it up or down with my monitor arm I’d feel more confident doing it holding the bottom part.The HDMI doesn’t support more than 165hz on this monitor so I had to use display port for that sweet 240hz refresh rate. You could use an HDMI to DP cable if you don’t have any display port option in your pc or laptop.The bezels are a bit thicker than I expected, You’ll notice it if you work or play in bright room. For me it’s no problem. My roommate has an Samsung g5 OLED and it feels smaller than that for some reason even though it’s same size. (Image quality is better than Samsung in this).It’s a glossy display, part of the reason why content looks better than Samsung g5. But in a bright room or average light room if you are watching something dark-ish you will see all the reflection on it. While gaming it’s not noticeable.Overall a little bit adjustment but very good for the price.

For the price this is an excellent monitor. At first glance the monitor may look a little dim, but if you mess around with the settings you’ll see the burn in protection settings are turned on by default. Specifically “Uniform Brightness” which dims the entire monitor. Pretty sweet for web browsing and coding and stuff, where some elements might be in the same spot for a while. Turning it off however, makes the screen look fantastic. Super deep darkness with vibrant colors, especially if you take the time to find the right hdr settings. All in all for 360 dollars this is a stellar buy.

Works extremely well.The image quality is top notch, color quality is amazing! Had no issues with connectivity everything is works great, easy to setup. The price might be a bit high, but when it comes to it, it might be worth it. Hopefully it has a long life. So far the durability seems great.I used to have a 1440p OLED which didn’t do as well as this one, had some issues. But so far, there haven’t been any issues with this one.
– Anonymous Reviewer
I LOVE this monitor! It is a huge upgrade from my 1440p oled that I had for 2 years. I will say it’s definitely on the expensive side but if you have the budget for it & on the fence, go for it!! The colors really pop & the 240 refresh rate at 4k is amazing! One thing I will say is the upkeep of the monitor is very important. Due to the glossy coat, it is easy to notice the littlest of spots when the monitor is off so it’s important to research how to clean it before buying. I am not knocking a star off for it because with proper care, this isn’t a problem, just takes time & effort.

Customer Reviews
So far 5/5 as long as it continues working as it does it’s phenomenal. Great quality for gaming, specifically stuff like new CoD games, fallout, l4d2, dead island 2, etc etc. haven’t used the dp cable yet. Think I had it upside down when trying to plug in so I gave up and used HDMI but still great for a gamer who relies heavily on having a great setup. K/d ratio in my prime on CoD was 4.00+ but getting old now, slowing down. Still 1.5+ on games I barely know (bo7, mw3 new). Fallout 4 is also great looking, and Diablo 2 resurrected in max settings. Running a Thermaltake PC with a 5070ti gfx card (I think!). Will report back later with more. Great frames, great color, fast response. Com ability is great so far with everything, and adjustments are easy and even auto a lot of the time. Sound not fantastic but it’s a moniter not a speaker.

I was hesitant to buy this because it has little to no reviews but the package came on time and display looks great. I use this primarily for gaming and visuals are on par with more expensive brands. Great bang for your buck.

No flickering. 240hz, displayport 2.1 (uncompressed), Dolby Vision, KVM switch, and 1/4″ tripod/screw for camera mounting makes this monitor a beast. You can hook a Xbox and Two PCs and switch between them with one mouse and keyboard flawlessly (and switch between speakers automatically too, if you use the monitor’s 3.5mm jack).The only downside of this monitor is that it uses a Triangular QD-OLED subpixel layout since it’s newer technology (versus traditional RGB stripe like some cheaper 4K monitors and IPS monitors), so fonts in Windows don’t appear as clear in as they would on other 4K monitors (like the Strix XG27UCS). However, this is only for windows fonts and not game fonts, so text in games will still be crisp. It’s a very small downside (and one you may not even notice if I didn’t say this) but some people care about this.The other downside is that it doesn’t have built-in speakers, which actually matters a lot to me. For $5 they could’ve added a single mono speaker and they would’ve been enough for me (I like having it as a backup or in cases where i don’t want to lug speakers around, or in case I ever want to mount it in a wall — who wants to attach separate speakers for a wall-mounted display?? Nobody, and all cheaper models of Asus monitors even have speakers).If you want the best monitor for the money, though, go with with bad boy. The extra money is well spent. I had the Strix XG27UCS before this, so I already had 4K, but this is a huge upgrade other than the font thing.I wish they also made the ports on the side instead of pointing down, but you can fix this problem with some shirt extension cables I guess, maybe (idk if they make DSP80 extensions that don’t hinder anything, but I’ll look).I’m also having a problem with windows not being able to turn HDR on (even in games), but I’m 99% sure it’s some software error I’m having, since it was working before and only stopped working after windows detected this monitor as two monitors, but I wanted to note this anyway.It’s a great monitor though. Only thing I don’t care for is the light on the bottom (would’ve rather had speakers than that light). The lights on the back are pretty neat, but again, I’d rather have speakers or smoother fonts.Biggest thing by far is the built in KVM switch. I’ve used KVM switches before but I never had one built into the monitor like this — wicked cool and useful.The menu isn’t very intuitive, but you’ll figure it out. Most menus are worse. Just don’t get annoyed and break the button or something, before you learn it.

Customer Reviews
Coming from a hardcore gamer of 15+ years. I had all the gaming monitors growing up ranging from 120hz to 240hz, in different resolutions. I love gaming but my time has been shortened as work became more frequent. I saw this monitor and noticed for one, it’s 4K and can output 120hz. It’s does the bells and whistle on height adjustment and yes, you can vertical tilt if wanted. It’s IPS so the view angles are nice and I currently have mine going of sRGB mode for color accuracy. I use a RTX 4080 Super for display out. I have used it for watching YouTube videos and shows within my first 2 hours of owning. NO DEAD PIXELS on arrival which is soo nice. I get very nervous about buying new monitors because of quality but Dell has done a good job. I do use it in Display port and not HDMI as this model has display. If you want HDMI with mini display, go for the QC model. Booting up was no trouble at all, ease of setup. Went to my nivida panel and enabled 120hz off the bat. The monitor does have G-Sync Compatibility but not CERTIFIED. However, it will work. I use the monitor on normal response for viewing and fast for gaming. I tested Warframe and Destiny 2 and Oblivion remastered all at high settings. The monitor keeps up for gaming but I wouldn’t buy if you’re fully going in for gaming. Dell has other options if like them. All an all, great monitor, great display, HDR works perfectly and the speakers. I almost forgot, the speakers have sound profiles built in so no need to tune if you’re not an audiophile. Colors look good, I’m not one for vibrancy but it’ll do good for the common Joe needing that quality that Dell has put out for this year.

First off, save yourself some money because this comes with a 2.1 HDMI cable. wish I knew that. Otherwise, I absolutely love it, I bought a monitor arm stand to go with this and they paired perfectly, so don’t worry if you don’t like the stand, it was extremely easy to put together, though I can’t speak for the stand that it comes with because I didn’t use that. The settings are very comprehensive with a wide range of versatile options for quality like a video game hdr mode and a movie hdr mode. Maybe I’m dumb but its pretty annoying to get the cardboard back into the box after you assemble the monitor.

Complete Buying Guide for Best 27 Inch 4K OLED Monitor
Essential Factors We Consider
When selecting the best 27-inch 4K OLED monitor, we look at several key factors that make a real difference in your experience. First and foremost is the panel technology itself – QD-OLED offers incredible color volume and brightness. We also scrutinize refresh rates and response times; for gaming, anything below 144Hz feels sluggish, and a 0.03ms response time is crucial for eliminating motion blur. Color accuracy is vital for creative professionals, so we check for wide color gamut coverage (like DCI-P3) and excellent Delta E scores. Connectivity is another important aspect, with HDMI 2.1 and DisplayPort 2.1 becoming standard for higher resolutions and refresh rates. Finally, features like HDR certification (DisplayHDR True Black), G-SYNC/FreeSync compatibility, and ergonomic stand adjustability contribute to a well-rounded and comfortable user experience.
Budget Planning
Let’s be honest, top-tier 27-inch 4K OLED monitors aren’t cheap. The technology is advanced and comes with a premium price tag. You can expect to invest anywhere from $600 to over $1000, depending on the brand, specific features, and any ongoing sales. While the “Best Budget” pick offers a more accessible entry point, it’s still a significant investment. When budgeting, consider what features are most important to you. If gaming is your priority, focus on refresh rate and response time. For creative work, color accuracy and HDR are key. It’s worth saving up for a monitor that truly meets your needs, as it’s a long-term investment for your digital setup.
Final Thoughts
Choosing the right 27-inch 4K OLED monitor can dramatically enhance your computing experience, whether you’re a dedicated gamer, a creative professional, or simply someone who appreciates the finest visual quality. The monitors we’ve reviewed offer incredible performance, vibrant colors, and deep, true blacks that only OLED can provide. While price is a factor, the visual payoff is undeniable. Carefully consider your primary use case and budget to make the best choice for your setup.
Frequently Asked Questions
Q: What is QD-OLED technology, and why is it better?
A: QD-OLED combines Quantum Dot technology with OLED. This allows for brighter, more vibrant colors and better color volume compared to traditional WOLED panels, while still retaining the perfect blacks and infinite contrast that OLED is known for. It generally offers a superior viewing experience, especially in HDR content.
Q: Are 240Hz refresh rates noticeable on a 4K monitor?
A: Yes, the difference between 120Hz and 240Hz can be quite noticeable, especially in fast-paced games. It results in smoother motion, reduced blur, and improved overall responsiveness, giving you a competitive edge. For everyday use, the difference might be less pronounced but still contributes to a very fluid experience.
Q: Do I need a powerful PC to run a 27-inch 4K OLED monitor?
A: Absolutely. To truly take advantage of a 4K resolution at high refresh rates (like 120Hz or 240Hz), you’ll need a powerful gaming PC with a high-end graphics card and a capable processor. Running demanding games at 4K requires significant graphical horsepower.
Q: What is the main drawback of OLED monitors?
A: The primary concern with OLED monitors is the potential for burn-in, where static images displayed for extended periods can leave a permanent ghost image on the screen. However, modern OLED monitors, including QD-OLED, come with various built-in protection features to significantly mitigate this risk for typical use.
Q: Is a 27-inch 4K monitor the right size for my desk?
A: A 27-inch monitor is a very popular size that offers a great balance between screen real estate and desk footprint. For 4K resolution, 27 inches is ideal as it allows you to see individual pixels without needing to scale the image significantly, offering sharp details and a comfortable viewing experience for most users at a standard desk distance.
In conclusion, investing in a 27-inch 4K OLED monitor is an investment in an unparalleled visual experience. Whether you’re chasing the ultimate gaming performance, refining your creative workflow, or simply want the best picture quality for your entertainment, these monitors deliver. Explore the options, consider your needs, and prepare to be amazed by the stunning capabilities of OLED technology.
