I have bought today a 40 inch 1920x1080 TV that has several inputs as RGB, HDMI, etc.
My idea is to use this TV as my computer monitor. I am already using it but I am connected right now using the VGA port of my computer.
As my computer (Mac) has a DVI output for a secondary monitor, I am about to buy a DVI > HDMI adapter.
Right now the TV says that it is using 1920x1080 @ 60 Hz. The TV is capable of going up to 100 Hz.
My question is: What kind of improvement will I see connecting the TV to the computer using HDMI, instead of VGA? Will it be sharper? Will I be able to increase the refresh frequency to at least 75 Hz?
I am not sure if my Mac can go up to 75 Hz at this resolution (it says it is an iMac 7.1).
