both should be the same.
TN vs TN at 1ms is as fast as it gets..
i guess pick whichever u like, price and looks.
there would be more to compare if it was TN vs IPS
I want to point out that Refresh Rate and Response Time are completely different.
See this thread for a succinct answer.http://www.tomshardware.com/forum/id-1855770/understanding-refresh-rate-response-time-relatonship.html
Response Time: Time for all pixels to change
Refresh Rate/Refresh Speed: How fast a frame is generated on the monitor.
Because these two models have the same Refresh Rate and Response Time and are TN panels, then they are essentially identical. Just beware of the refresh rates and response times. You can also get more into it by applying blurbuster/lightboost technologies.
120 HZ at 1 ms means a new frame generated every 8.333 seconds.
It takes 1 ms to change pixels so that means 7.333 ms of static frame is displayed before a new frame is generated.
If you have a 240hz monitor at 1 ms, it can generate a frame every 4.167 ms.
It will take 1 ms to change the pixels, and after 3.167 ms generate a new frame.
