Screen Flickers...

bananaboie · 04-13-2005, 11:51 PM

I have an annoying problem where my moniter flickers A LOT and sometimes turns tinted red. I tried changing the screen refresh rate but it still doesn't work. My moniter is a ViewSonic Professional Series P810 and set at 1280 by 1024 resolution with 75 hertz refresh rate.

try reducing the refresh rate to 72 or 70 somtimes reducing it will take care of flickering.

if the whole screen gets a red tint could be the solder on the gun has dried out because of the heat and needs resoldering

How about trying the opposite ? Raise the refresh rate to 85 or 100. What graphics card are you using ?
Edit: Highest you can go for 1280x1024 is 88hz. The specs call this "flickerfree".

About the red tint - like dai suggested - could mean a more serious problem like a bad soldering spot somewhere or a lose connection.

doesn't raising the refresh rate cause flickering or could case flickering? because the screen needs to process the image and refresh that many times and sometimes it skips a beat so to speak? or have i got this backwards?

a release of nvidia drivers caused flickering a few months ago,they fixed it in the next realease

I dont know about that - usually if the monitor cant display a particular refresh rate it starts shutting off or the screen gets all blurry or distorted.
When using a refresh rate of 60hz you can actually see it flickers, i find 70 to be on the edge... from 75 up you might not conciously notice it anymore but they say your eyes will still get "tired" faster on 75-85 than 100+ because even though your brain doesnt register the diffrence - your eyes still do.

Thats why i asked what video card he is using. You never know the problems he described could be from the card aswell unless he can rule it out by trying the monitor on a diffrent PC.

so 70 below is bad :: flickering

75-85 :: ok but not best

90 + :: good?

Yes basically. Of course the question is can your monitor achieve higher refresh rates on high resolutions.

AND - of course this applies for CRTs only. LCDs are a diffrent story.

I'm using NVIDIA GeForce4 MX 440 (Microsoft Corporation) and I already updated the driver. The screen still flickers sometimes so I think it is the moniter's problem. Should I consider just purchasing a LCD moniter instead?

it usually works out cheaper to buy a new one than to have one fixed these days unless you have a friend in the business
try another monitor on it to check
if you get an lcd,before you connect it drop your refresh rate down to the refresh rate of the lcd before you change it over as lcd monitors run at a lower rate than crts
