Picked up a
Sony X850D 55" from Bestbuy to test drive.
After playing with it for an evening, it'll likely be going back to the store tomorrow.
I used a trail of Displayfusion to split the display into six virtual screens. At first, I was enjoying having the screen sectioned off into working areas. However, I soon started to miss the physical separation of multiple monitors as it felt like my screen was becoming cluttered with things all vying for my attention. I can totally see how some people love the seamless borders and freedom that a large 4k screen offers, but it may not be for me.
I can also say that 55" is just too large for me, maybe I'd like a 45"-50" curved screen so it doesn't have me feeling so dwarfed by my desktop. It's like I'm misplacing things on my screen because there's so much area in front of me.
Gaming was another disappointment. I knew that 4K would be a bit too much to ask from a GTX 1070, so I set up a custom resolution for 1920x1080@100Hz (120 had strange artifacts). the 100Hz was great, but the image was blurred in Battlefield 1 and the desktop. Turning gfx scaling up to 200% in BF1 helped to clean things up, but not enough to make me happy. I'm unsure if there is a setting in my TV that I need to turn on/off, but so far I haven't found anything that helped.
To sum up, I'm just not enjoying a 4k TV as a monitor. Maybe a decent 30"-35" 4k computer display with a 1080p/1440 on either side to hold extras/game on.
The hunt continues....
