Soft-15KHz - slim new tool for 15KHz on normal vga cards
apocalypto:
Hi Sailorsat, I hope you can help me with a problem I am having using Soft15khz.
I have a Radeon 9550XL card which is connected to a 'VGA-to-CGA Converter Card' and then to my Sanyo 20ez Monitor.
I installed Soft15khz, the desktop resolution was set to 640x480. I rebooted, and after the windows boot screen, the screen went crazy with lines, colors and looked scrambled. I also had a vga computer monitor plugged in which then said out of sync range and had a black screen.
here is a picture of the Sanyo:
What I am wondering is if the converter card is splitting the 15khz signal in half, like it does with the 31khz signal. This is just speculation. Do you have any experience using these cards alongside soft15khz?
The only reason I am using soft15khz as well is so that I can run older games in low resolutions such as '224x256'.
Any ideas?? Thanks! :)

Soft15kHz is allowing the video card to generate the signal the monitor is expecting.. I don't think you should need the extra convertor in there.

Definitely yes and no, respectively.

SailorSat, congratulations on your work. :applaud:
I would like to ask about the syncs at soft15khz. I need to connect my Radeon 9550 to a SCART RGB to YPrPb converter box. I found a VGA breakout cable that split VGA in RGBHV, but I need RGBs to connect it to the RGBs to SCART adapter. If I combine the HV would I obtain s or do I need some sort of extra circuitry? Does soft15khz or ATi drivers support composite sync through VGA? :cheers:

Both ATI driver and Soft-15kHz support C-Sync, but you'll have to edit ALL modelines.
Easy way would be the H+V Twist :)
