I've got a G5 PowerMac with LG LCD, recently I've noticed vertical line on the screen depending on the colors on the screen, dark images show them up the most.

They are evenly spaced, in groups of 3, don't move and very thin. It almost looks like interference and not dead pixels.

The LG (W2261VP) is 21.5" full HD 1920x1080 and has worked fine apart from these lines that are there all the time but only viable one darker images.

You can try with different monitor just to be 100% sure, but your gfx card is probably dying :(

Happens with my 466MHz G4 when using the Rage 128 Pro GPU over a VGA [or any] connection. Fixed by sticking a spare Radeon 9600 XT into it.

Hope it's not the graphics card but I agree it could be, not a good time for monitors/GPU for me, the LCD on my PC is also playing up. So depending how that goes I might get a new one, test it on the Mac and see what happens.

How much are basic video cards for the early 2005 G5 Power Mac?

Time to check eBay :)

ETA - okay checked with the local Apple store and yes it sounds like the video card or LCD might be on the way out. I might need to get a new monitor for the PC I have so also, so when I can afford to I'll get a new LCD and test it on the G5 to see if the lines are still there. If not I know it's the monitor, I can use that on the PC for the time being as it's LCD is also having problems.

If it turns out to be the video then I'll have to look to eBay for one, either way it's gonna cost from $150 to fix, and I'm trying to save for a new iMac... come on Apple just release the 2012 model!

UPDATE - Okay I swapped LCDs between my Mac and PC, the lines did not appear on the other monitor, hooked up the LG and yes the line came back.

So I guess it's the LCD and NOT the video card or cables (used same cables to hook up other LCD) Well at least I know what is going on and it will cost from $150 to replace the monitor.

I can then had it down to the PC as it's LCD has a problem when its turned off and cools down over night it takes 10-15 seconds to come back to life in the morning. Hooking it up like I just did has no affect as it come right to life strait away.
