AMD mentions that it's possible to detect if a monitor supports "VBLANK". They obviously don't give any details as to how. So I did a little research, and found that the supported features of a monitor is stored in the monitor's EDID String
. Which can be found in this windows registry entry:
Export that entry, then edit the file in notepad and copy/paste the data to this webpage: Web Based EDID Reader
(edit out the slashes before you paste it)
That will give you a list of all the detailed information of what your monitor supports. It won't refer to a specific feature called VBLANK.
that what you are looking for is an extension called "Video Timing Block Extension (VTB-EXT)". Though I may be wrong about that.
If the output from that site says Number of Extensions: 0, then you don't have it (most won't of course). But if you have the VTB-EXT, then maybe...
I tried this on my desktop monitors, my HTPC, and two laptops (a Y510P and an old HP). No dice here.
Can others try this out, and see if we find anyone that actually supports this thing?Edited by wedge - 1/9/14 at 12:48pm
