I received mine yesterday and I'm slightly underwhelmed by the size of the 57" when compared to the 49".
So far, there haven't been any dead or stuck pixels, no apparent 'burn-in', and no popping capacitors, even at maximum brightness - fingers crossed!
The 57" is noticeably brighter and more vibrant than the G95T it's replacing. Having true deep blacks on a PC monitor is a first for me, and I must admit, I'm thoroughly impressed. However, when a small object is on a black background, there is obvious backlight bleed as expected from this type of technology. Having only 2k dimming zones on a panel this size simply isn't sufficient for achieving anything close to an OLED experience. Since I own a QLED TV, I'm used to the occasional halo effect that can occur. Personally, I prefer that to the constant burn-in anxiety that accompanies an OLED panel.
I've tested Battlefield 2042 a bit on the 6950XT, and it has performed quite well, considering the colossal resolution. At native resolution and low settings, it averages 60-80fps. With RSR at 5120x1440, it reaches 120fps on low settings. Ghosting doesn't seem to be an issue, but there's this odd behaviour I'm not accustomed to: during fast movements on a bright image, the outlines of the pixels appear to be very noticeable. They can't be individual pixels as they're minuscule. It's difficult to explain, but it gives the game a rather granular feel. I've experimented with various driver and monitor settings to no avail. If this persists I'll set up my camera with a macro lens to examine the issue more closely. Chances are it's just due to my tired eyes (the joys of having a newborn).
The core lighting on this model actually casts a slight illumination on the back wall (unlike the 49" version, which was a waste of time and electricity), and the 'CoreSync' feature that automatically adjusts the lighting based on the displayed image is a nice touch. It's nowhere near as good as Philips Hue, but it does the job to some extent.
So far I'm highly content with the 57" monitor. It's hard to justify the £2k investment over the 49", but the ability to have four full-sized windows open simultaneously is fantastic for boosting productivity - the primary reason for my purchase.
Will let you know if any faults begin to develop
