What are you trying to accomplish?
Your 244T is an excellent monitor with a great viewing angle.
I doubt that any other 24" monitor would serve you any better.
I had a pair for a long time.
If you have only one, why not consider buying a second for normal desktop work.
For me, I upgraded to a pair of 30" Samsung 305T 2560 x 1600 monitors.
When they worked, they were wonderful. Unfortunately, they were unreliable and Samsung stopped maintaining them.
You might consider a 2560 x 1440 27" monitor for the increased real estate. Very nice for games.
But, today, I would be looking at a 4k monitor. They are just starting to become available reasonably. The Samsung D590 is a 28" 4k unit that can refresh at 60hx with a displayport...
