With these monitors I would only be able to have 2 of the 3 on Display Port and the other would be on HDMI. I want to buy two more of these monitors but I am under the impression I cannot achieve 120hz with any other interface but Display Port. So I have a few questions.
-Can I achieve 120hz with HDMI or though any conversion between the HDMI/DVI ports on the card and the Display Port/HDMI connection on the monitor.
-If I cant get 120hz on one monitor how much will I notice a difference in 2D gaming, or if I use the non-120hz monitor for watching Blu Ray.
-Will the non-120hz monitor look different as far as its color brightness and such.
from what i found hdmi does not support 120hz at 1080p but dvi does if its dual link dvi.
more specifically "WUXGA (1,920 × 1,200) @ 120 Hz with CVT-RB blanking (2 x 154 MHz)" is supported via dual link dvi.
some people cant tell the difference between 60 and 120hz. some cant stand 60hz so its really up to your eyes. 120hz feels more fluid to me, at high frame rates that is. nothing feels fluid at 10fps.
brightness and color should be the same as a 60hz model. i could be wrong but i havent noticed any differences.
To add to the "can you tell a difference" thought, I'll add my experience.
Prior to having a 120hz monitor, going from a 60hz to a 120hz monitor, I didn't notice much of a difference at first, except when I really forced the issue, but spinning around fast, which produced a much smoother spin.
However, after using 120hz, with FPS well above 60, I notice when the FPS drop below 60 really easily now. 40-60 FPS feels jerky to me, where it didn't before. One of the biggest benefits I gain from over 60hz is that I experience far less motion sickness issues as my FPS go beyond 80 FPS with a monitor that can display more than 60.
