I got my G4 (insert cheers here), finally. I have it hooked up to my CRT monitors I was running with my PC. For the most part, the picture is okay, but I am unfortunately getting a slight flicker from time to time.

Degaussing the monitor often helps, but that's rather tedious.
I have experimented with different refresh rates and resolutions and the one that seems the most comfortable:

1280 x 1024 at 75 Hz


I have a Viewsonic E90f , if that means anything.

My question is would I get the same flicker on a Cinema display? Is there anything I can do to reduce the flicker? What resolutions and refresh rates do you guys run ?

Any problems?

I got Apple's 15" ADC CRT when I purchased a used G4 Cube setup. Available resolutions (with the stock ATI Rage 128 card) are as follows:

640 * 480 @ 154 Hz
800 * 600 @ 124 Hz
832 * 624 @ 120 Hz
1024 * 768 @ 99 Hz
1056 * 792 @ 96 Hz
1280 * 1024 @ 75 Hz
1600 * 1200 @ 64 Hz

I'm not positive if other resolutions would become available or not if I used a different card with the same monitor. The latter 2 settings produce a flicker that is noticeable to me and I would imagine would give me a headache if I used them for any amount of time. I currently run at the odd-ball setting of 1056 * 792 as it is the highest I can get before I get flicker. Anyone know how this resolution came about (or 832 * 624 for that matter)?! On a(nother) side note, I don't understand the reasoning to allow an setting of 1280 by 1024 pixels with an aspect of 5:4 on a CRT tube with an aspect of 4:3. I wish I could run at 1280 by 960 (4:3) like I've seen eMacs do. If anyone could fill me in on why these discrepancies exist, I might be able to sleep better at night.

Anywho, back to the topic at hand... If you get a noticeable flicker at lower resolutions, it sounds like a problem with your monitor (or possibly video card). Other factors may include the type of lighting in the room (fluorescent can be bad) or sources of electromagnetic radiation (some speakers or electronic devices with transformers in them).

You would get no flicker on any LCD display since they don't have refresh rates, the picture is always visible since each pixel has a transistor (switch) for each color and isn't redrawn with an electron gun. But of course there are tradeoffs (although not as many anymore) between CRTs and LCDs and that's really up to the user to decide what is best.

You know you wanna, why not just go ahead and match that G4 to a 23" Cinema Display!

Go get that Apple Loan same-as-cash for six months!

You won't be satisfied until you do ...

Yeah, I have to say - it is a little frustrating. The specs on my monitor suggest I can run it higher.

Is there any way to force the G4 to make it display the resolution ?





Any help would be GREATLY appreciated.
