What about this? It's a 24" 1080P/75hz IPS (better color) monitor. It's a Freesync monitor however you can still use your Nvidia card and utilize the higher refresh rate.
Ok, yea 1080P/60hz would be fine. If you play more FPS such as CSGO/Battlefield then I would try to find something with a faster refresh rate (75hz+) as it will make the gameplay smoother as long as you can keep the FPS up.
