Hi,
LG 23MP55HQ-P > http://www.amazon.com/LG-Electronics-23MP55HQ-P-23-Inch-Monitor/dp/B00HWHVNK0 (200 USD here)
DELL P2414H > http://www.amazon.com/Dell-WHXV7-24-Inch-LED-Lit-Monitor/dp/B00EMB4KVI (300 USD here)
ASUS MX239H > http://www.amazon.com/Asus-MX239H-23-Inch-LED-backlit-Frameless/dp/B00B1IAL7W (330 USD here)
The LG panel I listed has supposedly 5 ms so i wonder if it has that problem, one pro of this LG is that it has AH-IPS panel .
The Dell monitor has very good reviews and it is recommended for overall purposes, including gaming. It has AH-IPS panel like the LG and its flicker free, so it will be less tiring when looking at it for long hours, it has 8 ms in RT so it doenst have overshoot and according to pcmonitors.info it has very low display lag, compared to other IPS panels, and they gave it a Rank 1 in minimun lag for gaming. One of the cons for this panel would be the glow that IPS tend to have and that it is 6Bit instead of 8Bit color , though I dont know how much would that affect the user experience.
Regarding the last monitor, the Asus MX239, I dont know much about it, only that its also recommended for the mentioned purposes like the others, it has 5 ms RT , around the same size and same Res, if you know more about this monitor feel free to share your thoughts
Im looking forward to hearing from you
PS: Before I decided to go for IPS I was looking to buy a 144hz panel, but since my PC wont push so many FPS ive decided to settle with a better image quality. Here is my Rig http://imgur.com/a/u4pg2#0
