I can't recommend a monitor in your price range, I just want to put a few considerations out there for you to bear in mind in your search (may the gamut be with you!

) I learned these things when I built a computer for a photographic professional.
The issue with LCD monitors is accurate color representation. With most low-end monitors, color depth is 8-bit for about 16 million colors.
Professionals work with 10-bit color - some billions of colors. They also take care that the entire workflow path is 10-bit capable since any part of the workflow can truncate and lose the color depth.
IPS monitors represent a better viewing angle on large monitors since TN panels tend to have smaller viewing angles and thus the visual color is not equally accurate over the entire monitor.
No decent photographic monitor will come without specifications that state its color gamut - both in Adobe RGB and in sRGB. Neither of your monitors does that. Here is one (probably NOT in your price range, that does, though).
Asus PA248Q. Note that this is still 8-bit color, but note the sRGB specification. There is a newer 10-bit monitor, but I forgot it's name/model. Still in the Asus ProArt range, though, so you should be able to find it.
Note that IPS panels like this is typically a bit slower than TN panels that can have as little as a 1ms response time (better for gaming).
Finally, professionals use color calibration tools to ensure that all their device match color values.
