How to use SCART for our hobby
lettuce:
Well i installed windows xp and the ctr_emudriver_6.5 for my ATI card and hook the pc up to my CRT TV, when turning on the PC the TV screen seems to display loads of white dots on the screen that seem to scroll really fast down the screen, i can hear the screen turn to a different refresh rate about 3 time and then i just get a black screen with no white dots or scrolling... i guess the system is in windows at this point. Any ideas on whats wrong here?

ctr emudriver ??
- plug pc monitor on
- install windows
- install ati catalyst driver pack
- set comp to 640x480 60 hertz 32 bit
- copy soft 15 k to hd
- copy quickres to hd and set it to autostart
- start soft 15k , click install soft 15 k
- power down
- plug on mamescart cable and ur scart 50/60 hertz tv
- restart >bingo , after loading the driver ure in 15 k mode windows ( 640x480 interlaced , 32 k ). if u want progressive mode try lower resolutions
via quickres .. gl
some tvs may work well in 640x480 , others in 512x 448 or whatever u like . use tvs osd/potis to fix overscan ,image size , position etc.

The 4650 has better performance but 2 DVI ports & 1 S-Video, where as the 4550 with less performance has VGA, HDMI & DVI.
Which card would produce the best picture though, the better 4650 with a DVI to VGA adapter or the 4550 using its VGA port?

I decided to try and get this working with HD 4550 with Catalyst 9.5 Drivers but without any luck. I re-checked the cable numerous times and all pins are correctly connected and they all show continuity with a multimeter.
I have the cable setup as shown in the diagram below;
...but without the Audio cables connected and I used Pin 19 on scart instead of Pin 20, as per instruction in the site notes if you have a male to male cable, HERE
I boot up the pc into XP, start Soft-15 and install 15khz rate, Start Quickres and set to 640 x 480 and have it set to start on windows startup, I restart the PC change the VGA cable over and all I get is a fuzzy AV-1 sign in the top corner which stops fuzzing after about 1 minute (when into windows desktop I'm guessing).
The tv I'm connecting to is Sony Trinitron KV-X2502U, I tried tinkering with a few of the Service mode options in case the TV is the issue, but other than a few obvious options like interlace, screen pos etc.. I a bit clueless as to which, if any, of the options might help the situation. Here are the service mode options;
If anyone has managed to connect to a Trinitron, did you have to change any specific options?
Cheers.

forget the pin male to male nonsens , ure getting confused . scart pins a well defined . u should use a scart plug for soldering with printed numbers on at least one side . if the combined sync has to go to pin 20 so be it . u better cut and use a vga cable ( very old ones with pin 9 connected or new ones with coax rgb wires or audio included ) or solder it all complete from scratch . using a common scart cable makes no sense at all .
most sonys are very forgiving with the chosen cable shematics. my kv25 and kv 21 are working with a pin 9 5v cable and a hacked pc monitor cable i took from a defectice crt with bridged pin 20 to 16 and no pin 8 connected . but the molex thing wont hurt anyway . some tvs like grundig or philips may not switch to av/rgb without the fitting voltage on the scart pins . photo is taken from my kv21x5d ( 49 euro holiday cam and flash :) .
check the pin 19/20 problem . if cant find out whats causing the trouble ( cable , card , soft ,tv ) grab an old multisync from amiga or atari aera for testing.

The cable I've done is from scratch. A vga connector, scart connector, cable & resistors. I tried pin 20 first and then pin 19 without any joy.
Thanks for the info on the sony. I'll keep trying a few things.
