| 360980 | 2005-06-03 12:28:00 | Hi guys, my screen is starting to whine.. is that bad. Its a 17" AOC 7vlr CRT When I have it on 1024x768 and its on 85hz it'll slowly wind up to a high pitched screech and then I just change it to 75 and it stops. After a while I can put it back to 85 and it'll go fine for ages. I just tried to put it on 1154x864 (which is not a standard res which may be the prob) and on 75hz its fine. Until something white comes onto it like a window, or background, then it starts squealing like a ***** again.. So is it dying? Cos that would suck... also is the max refresh rate @ resxres controlled by the screen or the gfx card. Cos my mx440 powers the screen to 1280x960@60Hz and no more. So if I got a better gfx card I could run it at 1280x1024@85hz couldn't I? Cheers hamstar |

| 360981 | 2005-06-03 22:34:00 | Its not the GFX card thats the limitation. That monitor is only rated to 1024 x 768 @ 85 Hz. It will go to 1280 x 1024 but only at 60 Hz. Google will tell you that in 10 seconds. You run a risk of damaging the monitor running it above the rated settings. |

After a while I can put it back to 85 and it'll go fine for ages. If it is rated for 1024 x 768 @ 85Hz, and running it at that resolution & refresh rate causes it to complain, then yes, it probably is the monitor at fault. Before you condemn it though, consider sticking to 75Hz, 85Hz isn't really necessary. You could also try backing off the contrast and brightness settings as the additional load on the EHT generator may be what is tipping it over the edge. You may be able to minimise the effect by setting up the brightness and contrast as follows: Note: This procedure is best carried out in the evening under reduced lighting. 1) Set brightness and contrast to minimum. 2) Turn up brightness until you can just see the screen illuminated (this is setting the black level). 3) Turn up the contrast until you have an acceptable image. 4) Make minor adjustments to brightness & contrast to get the best image. Most computer monitors are grossly over-driven and their life expectancy is reduced accordingly. By setting up as above, you reduce the power requirements for the eht/scan generator and that may solve your problem. If it doesn't, think 75Hz max refresh rate or buy a new monitor.

| 360983 | 2005-06-04 13:27:00 | cheers for that... probly better on the eyes this way too... brightness on 48%, contrast73%... But that means I must buy a new monitor to run at 1280x1024... suxx0r... |

| 360984 | 2005-06-04 22:51:00 | cheers for that... probly better on the eyes this way too... brightness on 48%, contrast73%... But did that help it run stably at 85Hz (without the screech) or did you have to drop back to 75 hz permanently? Cheers Billy 8-{) :confused: |
