Ok so I found the soft15khz pinned thread in this forum..wasnt too hard to find.
Saddly though I dont quite get what i'm supposed to be doing. I run the executable and my graphics card shows up twice (i'm assuming once for the monitor once for the tv) but all the buttons are greyed out/disabled. What am I supposed to be loading?
Is there a master txt file of some sort I am missing that I need to load?
When that happens it's because of 2 things:
1) Card not supported
2) Drivers version
It's probably number 2. Now what to do:
- Download the oldest catalyst possible for your card (Catalyst 7.11)
- Go to C:\Program Files\ATI Technologies\UninstallAll and launch the uninstall application.
- Reboot
- Install the 7.11 drivers, then reboot.
- create a txt file, past the following content and rename it "custom15khz.txt":
;Remove some "too low" resolutions
remove 240x240
remove 256x240
remove 256x256

- Place the .txt file in the same folder as soft15khz. Launch Soft15khz. Select the secondary output (it's the DVI port, NOT the tv-out). Then click only the 15khz button. Set the DVI-output resolution to 640x480 and reboot again.
To know if soft15khz is working:
If you attach a PC monitor to the output port configured with soft15khz, and the PC monitor says that the signal is "out of range", or if the PC monitor reports the frequency (mine does) as 15.something, it's working.
