Due to popular demand I give you a comparison of 120Hz and 144Hz monitors. This time around we're comparing the ASUS VG248QE and the ACER GD235HZ. I also ran a second test of 144Hz vs 60Hz [see 8:30 in the video] using this pair, which both have about equal input lag making it a bit easier to see the jitteriness of 60Hz. The difference between 120Hz and 144Hz is much less than the jump from 60Hz to 144Hz but there is quite a difference between the two monitors and considering they cost about the same amount I am glad I went with the ASUS. Video recorded with my GoPro Hero 3.
I bought the monitors at amazon.com at the following links:
