If you have enough desk space and you are serious about content creation I'd recommend a 32 inch WQHD monitor.
You get the same pixel density as a 24 inch 1080p display so you don't have to use scaling in windows.
The amount of extra screen space you get is insane.
You can have tons of toolbars open and also have an actual 1080p preview of whatever you are working on at the same time.
The Philips BDM3270QP would be a good choice.
It has a AMVA panel with really good contrast and okay viewing angles and only costs about 550 euros on amazon.
Pixel-to-pixel response times aren't the best, certainly not optimal for gaming, but you can definitely play games on this thing.
I've played a couple FPS games on it, it's not as good as a TN panel when it comes to response times, but it's nothing too noticeable.
(Don't buy a TN panel, the color accuracy is shit)
The problem is, you won't find a panel that has no drawbacks. There are no perfect panels. Even the Dell U2715H that people have been recommending has its issues. Just google IPS glow.
You want a panel that's good for content creation, but you also want to game on it. These two things are polar opposites.
For gaming, you want low input lag and high refresh rates, for content creation, you want accurate color reproduction and good contrast. You won't find a monitor that has both (or if you somehow do, it will be probably out of your price range).
