Whether gaming, editing photos, videos, or watching movies, AG271UG gives you clarity with quality on a widescreen.

IPS Panel for Wide Viewing Angles

IPS panels give 178/178 degree viewing angles while maintaining consistent image quality and colors from all viewing positions. IPS panels have true 8-bit color depth that results in incredible color accuracy. The screen itself has a matte anti-glare coating that won't leave fingerprints or smudges.

    Customers like the size of the monitor. They say the colors are great, the size is enveloping, and G-sync makes everything better. They also say that the extra width comes in handy when editing song tracks and gaming at other times. The middle ground between 1440p, wide screen, and fast refresh rate, and the best specs of any ultrawide. The stand is weird, but the back is much shorter and fits on their desk perfectly.

    Great 4K, Great Price
    I built a gaming PC last May (GTX1080, 7700 processor, etc) and originally bought an LG ultrawide monitor. I was really new to all this and did a fair amount of research on PC components, but when it came to the monitor, I think I was so tired of research and didn’t want to spend a crazy amount of money.The LG ultrawide is cool, but it “stretches” some games, isn’t really supported by others, and definitely wasn’t taking advantage of my PC internals. I decided to shop around for some 4K monitors, and use the LG for music production. I was first looking at a Predator, but didn’t feel comfortable spending almost $700 when basically every other review was bashing their horrible QC problems. I found the AOC AGON AG271UG and it was right in the price range I wanted and had decent reviews. I was stuck between this being only 60hz or upgrading to a 144hz, but I don’t really play competitively so thought the extra cost may be unnessecary for my needs.I bought the AG271UG 27inch monitor with Prime and two days later it was at my door. Took it out, hooked it all up and started it up. I noticed split right down the screen, the left half of the monitor was red (picture 1) and could be seen when on the desktop (picture 2). I fiddled with the settings but didn’t help. It was very odd, it would cause blacks to be reds, but it was transparent so when I had Google Chrome open it would only show through the blacks. I restarted the monitor and it seemed to correct, but came back shortly after.I looked online and didn’t see any info about the problem. I’ll be honest, I was bummed because I read so many monitor reviews about garbage QC issues and knew I received a lemon. I contacted Amazon Support and sent it back the next day (super easy process). I debated about ordering the same monitor or if that was a “sign” to get something else. I decided to order it again and it was delivered the next day, super insanely fast shipping. I have been using it for two days and doesn’t seem to have any bleed, dead pixels, or any issues (picture 3).I’m still messing with the color settings, but I really like this monitor. 27 inch is the perfect size and I love how easy it is to adjust the viewing angle and height of the monitor. Using 4K mods in Fallout 4 and playing Divinity: Original Sin II, I can see all the colors really pop and see the difference from my old monitor. I also checked out some 4K videos on YouTube and they look spectacular. I’m also using the G-Sync since I have the Nvidia gtx 1080 and haven’t really had any issues game performance wise. The speakers aren’t that great and the monitor menu could be updated, but those aren’t things to cause too much fuss over.Overall, really happy with this monitor. If you’re looking for an entry 4K monitor and don’t want to break the bank, I would see definitely check this out. Sure it’s only 60hz, but for the price some sacrifices will be made. Sure my first monitor was messed up, but an easy return process and a insanely fast delivery of the second and everything is good! Bring on Far Cry 5!!!
