Thought I'd share some of my thoughts, been using my 42" C2 for around a a few days now. I used it mainly for productivity, but do game on it too. I have a 60cm depth desk, but it's right back against the wall.
The TV itself just looks great! Super slim and looks amazing on the desk. The picture quality etc is also fantastic. Games look fantastic, vibrant and super smooth with the 120hz.
I am finding some issues with the sheer size of it though. I'm not sure my desk being another 20cm deep would make a huge difference, but it might. Nevertheless, the screen feels probably too large for a productivity monitor for me at the moment. I went from a curved 34" 21:9 LG IPS Ultrawide. The huge increase in the screen real estate is pretty much all vertical and I am not finding that space massively usable. What I find I am doing is almost forcing myself to put stuff (Inbox, Slack, Dashboards) at the top of the screen to try and use the space up, and having a zone at eyeline for my main thing I'm working on. Fanzyzones is great for that mind though. Tbh, I have ended up using the middle section of the screen mostly. The extra real estate is filled with stuff that clutters my brain
For gaming, some stuff plays great! Cyberpunk looks fantastic on it (3080ti). What I have found with some games though is that I am not able to make best use of the screen size and resolution. AOE4 is a good example where I was actually seeing more in-game area with the 21:9 1440p rather than 16:9 4k. The zoom is just too tight. The games do look amazing on it though. It might just come back to it being very big and maybe too close.
I've switched back to my 34" ultrawide to test it again after a few days on the 42". Will use it for a day and switch back to the 42". It is great to be able to use them in the same space, for the same stuff and properly compare and see what I prefer. Not really something you can do reading specs etc!
