[Please Help] Best VGA to Component option?
renatopdalencar:
Hello there!
I need indications for the best options available at the moment to connect my PC using CRT Emudriver and a graphics card with VGA output to my consumer Sony CRT with component input. By best I mean the ones with superior video quality. Lots of people talk about the Retrotek VGACTV1, but I can't find it anywhere. I saw people praising the Audio Authority 9A60 as an even better option, but it has been discontinued and the only one I could find on eBay is in the UK and doesn't seem to ship to Brazil.
I ask this because I got a Jasnet (brazilian company) VGA to Component transcoder which was made with CRT Emudriver in mind, but something is very wrong with it. When the transcoder is plugged to a power outlet, I get a very purple tint on the screen even with the PC turned off, instead of the usual black. And when I turn the PC on, things get worse, as you can see by the images attached.
Thank you in advance!

Ok, a purple tint can be an indication that a device has been set to component input and you’re feeding it VGA input. A green tint is the reverse.
Your second pic might be the main problem though. If this screen is stable, not rolling either vertically or horizontally, then three side-by-side images indicates a 45kHz input to a 15kHz screen. Three horizontal sync circuitry is only fast enough to catch every third sync pulse at that rate. Two side-by-side images would be 31kHz.
You should follow Calamity’s guide to installing crt_emudriver to the letter, first making sure to find the right version of crt_emudriver for your OS and video card, and then the right guide because there are two.
I’m not sure if this is affecting the colours, but I would try to fix this first. The guy who makes the retrotek stuff is reputedly a bit crabby. I would suggest looking on the shmups hardware forums as there are lots more listed there, like Mike Chi’s unit, Lunxbot3000’s unit, or the J-rok, to get you started. I’ve never heard anything against the Jasnet one though, so I’d say get a single stable image up on the screen first, and the email whoever sold you the jasnet transcoder for tech support if you can’t get it to work.
To that end, what cable are you using, have you swapped some of the inputs around?

Vgactv1 is now vgactv2, and no longer on Ebay. As far as I know they are only available through his website now. I have the vgactv1 and have had no issues with it. I've read some criticism that it has some power issues, and some other complaints, but it has been solid for me.

I was following a different tutorial. Now having followed Calamity's tutorial as you said for HD5000+ cards (mine is a R7 350) the problems are almost gone: no more purple tint or tripled image. The thing is now when I boot up and up until the login screen the image looks fine, but after I login to Windows, the image starts to shake a lot. Why could that be?
Please take a look:

When you plug a different video source into the TV, a game console or whatever, is the picture perfectly stable? Have you tried both enabling and disabling composite sync in crt_emudriver? Have you tried going into the TV's service menu and adjusting... I don't know what the horizontal hold adjustment on these is called. Maybe phase? (if you're going to go into the service menu, be careful, and write down all the settings before you change them, and make sure you can go back.)
