Write a reviewAmazing product - Love the smoothness of the 540hz I play valorant and cs2 and some forza oled is king
Okay Monitor - New Tandem Woled technology still needs more time. Has really good blacks in bright rooms but screen is very grainy. Grey banding is also a real issue with the new gen Woled monitors.
LG ultra gear Oled monitor - The colors were beautiful and the settings offer a multitude of customization of potions
Lg 27 moniter - Nice moniter but pricy. Very clear great for gaming
in screen tear - just in 2 months terrible screen and pixel tear and lines
Best quality I have ever owned!!! - Let me start out by saying the switch from 1080p to 1440p is nuts, and don't get me started on the 4k. I mean I feel like I am seeing colors a whole new way. By far, this has been the most impact full upgrade to my setup. Would I recommend this monitor? Is 1+1=2? The answer is yes. This monitor is worth every single penny.
Amazing product, dual mode is for what? - Very good 10/10 have the monitor for over a month now and gameplay feels smoother than ever, did have to make some optimizations to get 540fps consistently on some games. If you dip below the refresh rate you will experience some screen tearing. Dual mode is pretty much worthless unless you're fine playing on super low res and not being able to tell what things are.
fyaaa - it’s OLED and it’s gives true black colors… should’ve bought this years ago
Everything you could want - This monitor is probably the best purchase I have made since building my pc, it allows me to access the high frame rate I would like and looks beautiful while doing so, 10/10 if you can reasonably afford i would highly recommend it, your gaming experience will improve
One the best - Definitely number 1 monitor out there I enjoyed it allot made movies and gaming very nice
Great display - Display quality looks fantastic, I’m able to get a more accurate color gradient when I’m working on art.
Awesome monitor - great price and its 540HZ, awesome specs, nothing negative about this monitor.
Great monitor - Fast response time great quality 4K 1080 P 500 Hz a great monitor for how much I paid every other monitor I look for was $1000 for these hertz so it’s not that bad. I advise you to get one.
So far, so great - My eyes tend to be sensitive to some monitors, which causes me to prefer this type of matte finish to the newer glossy finishes that can maintain their deep blacks ... this is a personal preference, but if you hate the matte finish on recent LG monitors then you won't like this one either. Like any monitor you are going to want to mess with the settings a bit and I can't speak for the HDR as I don't use it (again, my eyes don't handle it well), but it handles text better than older OLED and can't complain about the refresh rate at all. For me, this monitor has been about as close to perfect as possible.
LG UltraGear 27” Oled - This oled monitor is definitely a piece of technology, being able to switch between 540hz oled to 720hz HD is a unique experience I can only have because of this monitor. This is not my first oled monitor but I definitely think it’ll be my last, the price is definitely worth every penny. You will definitely need an upgrade to your setup to get everything this monitor has to offer but even when I had a lesser set up it still over performed every monitor Ive owned in the past. 10/10 monitor
Good screen great colors - It’s a very good monitor, especially for gamers who loves to experience good graphics and colors with high hz
