My Dreamcast Failed Experiment

[HyruleHero]

I was trying to get some HD out of my Dreamcast with no luck maybe you guys can troubleshoot it or offer suggestions?? First things first, I have a ton of consoles hooked to my Samsung Flatscreen, the ne'wer TVs lack a lot of inputs. I have 1 set of either component or composite hook up, my choice. So I have some older consoles Dreamcast, Saturn,N64 and Sega Genesis hooked up. Now I wanted my PS2,Xbox, Wii hooked up componetly but I had the the problem mentioned above. So I have all 3 of those hooked up to a component switch and then to a component to HDMI converter to put in my 1 of only 2 HDMI inputs. They work great. So, I bought a Dreamcast VGA cord(not box) online(no VGA input on my tv), a VGA to component cord, a stereo jack to Audio(red,white) cord. So basically it's the Dreamcast VGA+VGA to component cord, to component switch to component to hdmi converter,hdmi to TV. Yeah, I sound like a mad scientist, this might not even be possible but I am bored. The results are sound, no video. Is there a setting you need to adjust on the Dreamcast? Any tips or suggestions I would appreciate it. And yes I understand how idiotic this may all sound to you guys....hahah! Thanks in advance!

Just an FYI, some games are not VGA compatible.

An adapter won't work. You'd need a box to actively change video format. That result was from sending VGA video into the converter's component input.

There is no easy Dreamcast component mod for maximum game compatibility and image quality. Some titles are incompatible with either SCART or VGA.
Even installing two encoders to handle both of those, still wouldn't run the apparently composite-only karaoke module...

VGA to component cord?

If i'm understanding this right, and i think i am, you're sending a vga signal (31kHz) straight to a component input without scan conversion. If you really want to be a mad scientist and get this thing working, your gonna have to gut your Dreamcast VGA cord open, find out which wire pin 6 or 7 belongs to, and cut one or the other. This will de-ground the pin and send a 15kHz signal instead of what your currently outputing.

Either that or buy a new tv

I don't see how that would help. It'd still be RGB, rather than YPbPr that the HDMI converter wants.

You could convert VGA to DVI, and from there use a DVI-to-HDMI cable.

Not as simple as it sounds, since you'd be converting VGA to DVI analog, which you can't quite so easily convert to DVI digital which is what you'd need to convert to HDMI.
