That is a nice enough display and would be an improvement over what you have now.34" is likely too large for my needs/sitting distance. But $400 is my budget!
I'm leaning towards this Asus: https://www.amazon.com/ASUS-PB277Q-...16&sr=8-4&keywords=asus+27+inch+monitor+1440p
I think this will be the upgrade I'm looking for:
23" to 27"
1080p to 1440p
60hz to 75hz (not sure that will even be noticeable).
But I'm waiting to see what the holiday sales bring!
