I'm looking at this TV to be used primarily as a PC monitor with some TV and movie watching on the side and I intend to switch between 120 Hz 1080p and 4k 60 Hz resolutions often. The only feature I'm concerned/curious about is the missing judder free 60 Hz capability. If I run games and movies in 120 Hz 1080p will this eliminate all judder? I currently run my PC on a 1080p 60 Hz TV with no judder reduction features and I don't think it's a major issue but it can be noticed. So, am I overreacting to think it might be a deal-breaker for a primary PC monitor TV or is there another model you recommend more? The X900E is nice and does judder free 60p also but the image retention on it might be a worse trade-off for me.
