I think it would be way too big but guess you would get used to it. It has crossed my minds since 4k monitors are way more expensive than 4k TVs and I want to go 4k. I think I will bite the bullet and get a good 4k IPS monitor though. 32" would be a sweet spot I think, would not want to go bigger. We got 3x 27" 4k at work and 1HD for daily tasks/email etc, I could almost get used to that as may daily use monitor tbh. But text is kinda small. Would maybe get eye strain over time.
