My Quicksilver 01 seems to flip its lid sometimes with 16:9 resolutions

Wondering if anyone has a fix for this, because I really wanted to keep it on 10.3.9 but I had to upgrade it to 10.4 to escape this issue.

I was playing Alice under 10.3.9 with my GeForce 4 Ti 4600 (shouts to Justin Morgan for hooking me up with that, btw) and it worked stupidly great under 720p. Played for a while, closed the game, and noticed when closing the game that I now only had half my display, and it was ghosting pretty badly on a Dell 27" 1080p display (running it over DVI to HDMI. Conversion t e c h n o l o g y!) The only thing able to bring it back to usability was setting it to a 4:3 resolution, as nothing else would work.

What's odd is rebooting into OS 9, 1080p works just fine. It was only in OS X that it was going horribly wrong. Refresh rate and everything else checked out, but no matter what I did, any 16:9 resolution was completely unusable. Sigh.

Has anyone experienced this? Were you able to fix it? Have tried a PRAM zap, didn't do anything sadly.

EDIT: To anyone happening across this, I think it was a precursor to a bigger problem because now the G4's dead to the world. Still acts like someone's awake in there, but as far as video output, completely comatose.

Is it the mac or the GPU that died? Does the QS work with another gpu? Another user on MR purchased a Ti4600 for his quicksilver and also had GUI and resolution issues ie: entire portions of the video image are caked with huge blocks, distorted colour tones and other unwanted artifcats at 720p and 1080p, 50-60hz, running 10.4.11. These cards unfortunately seem to not age well.

Did you try the ADC side of the card? That card has separate SI TMDS (Silicon Image Transition Minimized Differential Signaling) for the DVI and ADC signal. If you're lucky, the ADC side is ok and will not exhibit the distortion.

Weirdly enough, the solution was to stick my Elgato HD60S inline with the DVI to HDMI adapter. Because for some reason the G4 was having a bit of a time reading the EDID of the display, I guess? Having the HD60S present itself as a 1080p capable monitor made it work fine. Not sure why.

Man, that is weird. Is it possible that a monitor is too new? Anyhow, glad you got it working. Although I dont have a need for screen cap, HD60s seems like a handy thing to have around.
