Would agree that at this price (Dell or this one) it should not be a panel lottery
Overall I believe that you have a few options:-
1. Have another try with the Dell (but back to luck of the draw.)
2. Try one of the va panels e.g 40" Phillips or AOC /Ben Q 32".
3. I was very tempted to get the 4k Benq 32" - only prob is that it is out of stock at the moment.
4. If you can cope with it go for the Hanspree 27" IPS and hold the 'big' purchase until the next gen of monitors are out.
Good luck
