Does this mean my graphics card is not compatible?
EDIT 14/12/2016: The title of the thread no longer matches the problem I am asking help for. It should be changed for accuracy (but I don't know how it's done :p). Go to post #4 for the update.
Hello. I'm trying to get a 15 kHz output but I haven't been able to do it. [Noob alert :p]
This is what I do: I download soft15khz and quickres; I run soft15khz and enable 15 kHz for my card. Then I switch to 640x480 resolution (or not) with quickres. These programs are always run with admin privileges. Then I reboot.
I have done it with two computers (both graphics cards are implemented):
* Intel HD Graphics 4000, Windows 8.1 x64
* NVIDIA GeForce 6150SE nForce 430, Windows Vista Home Premium x86
After the reboot, everything is the same: the resolution choosed with quickres is kept, and I see it through the VGA signal. So the 15 kHz mode is not working (if connected to TV, nothing can be seen).
Does this automatically mean none of these graphics cards won't work for a 15 kHz output?
Thanks.
