What are you planning to do? Words, Data Analysis, Photo Editing, Video Production, etc.
For a general purpose use (1920x1200), I have continued for many years to be pleased with the Dell U241M series of screens.
In February this year, I helped one user downsize from and older Dell 30” monitor to a Dell Ultra HD 4K Monitor P2415Q 24-Inch. This is 4096 x 2304, with stated 1000:1 contrast ratio – at $350 Amazon Prime. This is also quite nice.
But, again, only you know what you need in terms of resolution and color gamut.
