Terrible text rendering with this RGWB WOLED panel

Terrible fringing on text in Windows 11 with and without ClearType on. Tried using MacType to adjust the font, but there aren't tools made for RGWB panels. Microsoft doesn't seem to care about addressing this issue. I would avoid all OLED monitors until this is fixed.

Horrible VRR flickering

I really wanted to like this monitor since everyone mentions how great OLEDs are. The first issue is the matte screen this has, which I new before I bought it, but I didn't realize it would cause a light bleeding/blooming effect similar to my older IPS monitor. OLEDs are known to have poping colors and no light bleed. The second issue, which was the dealbreaker for me, was the horrible VRR flickering. Whenever I moved my mouse or do anything it the lighting would flicker. It was far too distracting. Given the how long OLED technology has been around, you'd think this issue would have been ironed out.

great monitor, noticable flickering with grey

the monitor overall is great, loving the colors, refresh rate and resolution, not super noticeable jump from my previous monitor but the colors are alot better than my previous IPS, my two issues are with the stand and flickering when the screen is mostly shades of grey, the stand doesnt go as short as i wish it would and flickering is very noticeable when the screen is mostly grey but its not a deal breaker especially at the price point though i do wish that when it automatically did image cleaning, when it gets turned off, it had the rgb colors same as when you do it manually as it makes me doubt whether or not its actually cleaning

Good for $550, is not what it claims to be.

The Good: Buttery smooth, rare stutters, no tearing. decent color. Worth every bit of $550 paid. The Bad: Model is advertised as 1500 nit monitor is only 600, also advertised as VESA certified but windows does not recognize monitor as VESA certified either. Thought this could be a driver issue but there are no drivers for the monitor on support site. If it stays at lower price, worth it, but if it goes back up to $850, there are better options out there.

Good but may be great in the future

This tandem Oled is still early in its lifecycle so we don't have any suggested setting guides or real reviews yet. Overall its bright and the SDR colors seem vibrant for an W-OLED, out performs my 3rd Gen W-Oled in these areas. Text clarity actually looks better than my 3rd gen W-Oled and isn't an issue for gaming and light-moderate productivity work. Windows HDR still is lacking, as with all monitors, and gaming HDR is undetermined at this point. The display modes seem to all have built in color mapping, although it's hard to tell exactly what they are (gamer 1 vs gamer 2 etc) and how peak brightness factors in to overall brightness and color contrast etc. Hopefully there will be some firmware updates that make this Oled rise to the top. The matte screen isn't as distracting as I thought it Would be and I came from a glossy Oled. Overall I'd buy again but if LG isn't careful the go to will be the glossy ASUS version. LG - please send some test units out to the big testers!

Disappointing release from LG

Much better color and full screen brightness, but has crushed HDR black levels, poor HDR EOTF tracking, a hazy matte screen, and blown out highlights in HDR. SDR also has issues, but not as bad. This monitor needs a lot of work. It shouldn't have been released in this state. LG does great on TVs, so im not sure why monitors keep having so many accuracy issues, especially in HDR.

Fantastic Monitor with Abysmal HDR implementation

1500cd/m² (@HDR 1.5% APL) is straight up a lie with this implementation. When you enable HDR in Windows and then go to advanced display settings, it clearly states that the peak brightness of this monitor, as reported by the EDID in the monitors firmware, is 604 nits. That is incredibly far off from 1500. Even if you try running Windows HDR calibrator, it is apparent that this monitor's firmware was built around a 600 nit peak. Even if you use CRU and put in 157 for peak HDR brightness (1499 nits) to manually lift this limit, it is extremely apparent that putting values more than 600 nits in games will absolutely blow out the image due to aggressive tone mapping. This monitor doesn't have HGIG or a way to turn off or adjust tone mapping, so there is simply no way to have a decent HDR experience (unless you are fine with 600 nits peak) without LG releasing a firmware update for this monitor. Everything else about this monitor is fantastic though, that is ultimately what made me keep it as I play the majority of my games in SDR. I'd only recommend this monitor at the $599 price it was a couple weeks ago. $850 is outrageous for 1440p and a totally bungled HDR implementation. If they release a firmware update to fix HDR, I'd easily give this five stars, but HDR alone is so bad that I have to take away two stars for now.

Best OLED display minus HDR

Definitely one of the best monitors I've ever had. Very impressed with the color, brightness and overall build quality of the monitor. The only thing that makes me consider returning it is the HDR implementation. For some reason it just completely washes out all the colors. Nothing in the OSD is able to restore any of the vibrance, so there has to be some tweaking done in various control panels. Even then the overall image looks poor. HDR was a feature I was excited about having, so I may return this monitor.
