Good to know it's working better. But like Terry said, go ahead and get a new one, anyway. Also, if this is a computer you're on a good bit of time, I'd go with an ultrawide. I switched from dual 24"s to a single 32" ultrawide and couldn't be happier (well, I'd be a little happier if it was the 49" ultrawide, but that thing is more than I'm willing to spend on a monitor).
Anyway...on the ultrawide, I can open 2 windows, side by side (just like I have, now), and have plenty of real estate on each. And I don't have a bezel in the middle, either. Plus, I do a tiny bit of gaming on it (just some D2 Resurrected) and it sure makes it better with the extra screen size.
