What will be driving the monitor? Console, PC, what GPU etc.?

What's the budget and cost of those monitors?

Without any other details I am taking the 32" 1440p monitor - just more to see. But it might not be the right one.

1080p at 27" is too low resolution now for me. 24" 1080 is fine.

However, I would certainly look them up on rtings.com before buying.
