    Hello everyone at MacRumors!

    Yesterday I bought a secondhand G5 and I want to use it as a sleak HTPC.

    2x PowerMac Dualcore 2,5 Ghz
    1,5 GB RAM
    Nvidia 7800 GT Vcard 256MB
    250 GB harddisk

    I am pairing it with a Sharp Aquos TV via a HDMI --> HDMI cable with a DVI block on the G5. I am running into some issues which I hope you guys can help me with!

    Issue #1: The G5 will not give vision via the HDMI --> HDMI cable and using only the Sharp TV on its own. It makes noise and when I change the channel to the proper source its fans start blowing at top speed and it does that non-stop. Sometimes I see the apple logo at startup but this is roughly 50/50.
    When I plug in a VGA --> DVI display in the other port it WILL detect that and go to the desktop pretty fine. At display settings I can even see the Sharp, set the resolution and disconnect the VGA screen and it keeps working... At system restart however, it goes back to line 1 of this paragraph.

    Issue #2: When I do get it in working condition via the VGA screen 'trick' the screen does not fill my TV all the way. With Overscan on it goes a tad to far and the top bar falls of completely as well as 2cm's on both sides and 0,5cm's on the bottom.

    Any idea's how to solve this?!

    Kindest regards,

    A G5 is a terrible HTPC. Its very noisy, sucks a lot of power and makes a lot of heat.

    Fair point, I really like the looks of it though. What are you using yours for? Main PC?

    Late-2005 Dual 2.0GHz - my main PC. I used to own a MacBook, but it was stolen last month and the police couldn't track it down, so I us my G5 daily ever since...
    G5 is a beast, but not really good to be used as a HTPC, exactly for the reasons mentioned above. The late-2005 PMG5 has a 1000W PSU for a good reason.
