First monitor is TN, which offer poor color quality/viewing angles. Good if you want it for highly competitive FPS games but not much else as they usually offer the best response times.
Second monitor is curved and VA, VA has nice image quality but gets a little washed out at higher frames and the curve at smaller monitor size doesn’t really look right imo. Go ultrawide if you want a curved monitor.
By default the third is the best choice for me, IPS is the best monitor tech for all around use. Great viewing angles/color reproduction and nice enough response times to be an all around top choice for gaming/general use.
So while we are on the subject of screens, I have the new gen OMEN with the RTX 2060 and I got it with the 300 GHz refresh rate but the 15 inch is sadly to say a little small so I want to go with a monitor but I’m also curious if I should get an external GPU to go with it… would it make it better or would it not do anything I’m not really sure how they interact.
