Looked at the 34" 3440x1440 displays again at Best Buy. They still look very small on the display shelf, but I think it's just the way they are on the shelf. I watched it a bit to try and get use to it, then went back to the 1440P 27". They both seemed small, but I think they'll be fine when I get it here on my desk. Hell, these are 22" monitors I'm using now.
The longer I looked at the ultrawide and then went back to the 27"...you guys were right. I think I preferred the wider display.
Going to switch gears and research those a bit. Open to suggestions on specific displays.
