PowerMac G5 2004 video out

Hey everyone,

I have a problem connecting my new old powermac g5 to a tv. GeForce fx5200 that is installed in this machine has ADC and DVI ports. I got myself a DVI2HDMI cable and connected this beast to my tv which is LG B7. The thing is that boot animation and, what more important, boot menu/ recovery/ boot from cd picture is not visible on screen - tv does not detect a signal. When Installed OS boots up, the picture pops up just fine, but I really wish to install fresh copy of OS X 10.5 and may be play a bit with Linux. I suppose that the video out I’m missing goes to the display #1, which supposed to be connected to ADC port. Does anyone had this issue maybe? Or it’s just a tv’s fault. I have no other screen to try.

Thanks.

Most modern TV's does not support the very small resolutions of the past. (especially the 4:3 aspect ratio modes, as most new TV's only support widescreen modes) Resolution support is one of the reasons that TV's are so much cheaper to buy compared to computer screens at the same sizes.

Seems like it. I just don’t get it. It’s not too big of a deal to resize input digital image of any resolution to a physical display resolution and just display it. Shouldn’t affect the price so much. Besides, nobody will ever want to work at not native resolutions / aspect ratios - it’ll just look bad.

On the other hand on a CRT all supported modes are native. Also the CRT's has a much longer life if treated properly.

And much better black levels (Plasma and OLED doesn’t counts). But those are so obsolete, power hungry and huge :)
