LG 48CX dropped to £848~ at Costco. Tempted to drop my preorder for it, but I'd only use it for gaming/movies instead of Windows to avoid burn in
FWIW. I had a 55" B8 I used as a PC monitor for around 2 years, used it in my room as monitor during the day and then to watch films/tv shows and YouTube in the evening - as well as sport. Never noticed it had burn in until I went to sell it and went to do a test, taskbar at the bottom was burnt in - could swear I never noticed it until I did the test (using basic YouTube video). Ended up using it in the front room as main TV instead of selling it, as it is the bottom bar I never notice it during films (vast majority of the time you have a black bar there anyway) but occasionally notice it watching football on a green pitch - you have to look for it though.
All that said, I upgraded to the C1 for my monitor (120hz @ 4k etc) and now use Windows with Taskbar hidden. I expect there will be no burn in if/when I look to sell this in a few years, only noticeable burn in on the B8 was the taskbar, which makes sense as it was pretty much on 10 hours a day, every day.... Oops.
Long story short, I am not sure burn in is such a big issue if you hide your taskbar and are not daft with it like I was :--)
EDIT - Also re 27GP950 - if the numbers are accurate on rtings, that monitor has worse input lag than both the CX and C1. I don't get how, surely there is some mistake - but that is pretty unforgivable for a PC gaming monitor to have worse input lag than a TV if true.
I had one of these on pre-order with LG but cancelled it, the CX and C1 (I had one delivered via eBay but there was a chip on the screen so had to send it back and decided to just get the C1) are incredible to play Doom Eternal in HDR (with Gsync off, which really lowers brightness for whatever reason) and other FPS games on, which were always going to be the more questionable games to play due to size of screen and input lag... Quite a few others I have spoken to have said the same re the 144hz gaming monitors, pixel density seems the only real reason one might opt for them over the CX/C1 - and screen size I guess. Still tempted mind, just to see what they are like...
