new 22 inch widescreen has screen flicker...

  athenrye 21:18 13 Feb 2008

ive just set up my father in laws new flat screen acer 22 inch lcd

it has very noticeble screen flicker
i have it on the highest reccomendation of 1680 x 1050

he has xp with 512 mb ram and onboard graphics card

it was powering the old monitor not too bad
any ideas why the screen flicker is there

he has bad eyesight and had hos old monitor on 800 x 600 i changed that and made his fonts xlarge and shpwed him how to zoom web pages

surley ill not need to put his new flatscreen resolution way down to that

Maybe his on-board graphics are not up to the job of running the new monitor - in fact, probably more than a 'maybe' ........ even a cheap graphics card would be better than on-board!

This looks like the driver for the on-board card is having difficulty refreshing the screen. update the on-board graphics driver.

If this does not work, post the on-board name and operating system...

Agree with TT on this, but worth a try with the driver...

Is the cable from pc to monitor all one cable ?
I had problems with a monitor a while ago because I had an extension cable linked in to lengthen distance between pc and monitor
Also check refresh fate against manufacturers spec.

hi guys thanks
its the one cable, not a long one

its more than likely the graphics card as i thought it might be
i didnt think of tryng to upgrade the driver
how do i do that?

how do i check or alter the refresh rate a well?

i might just buy him a new graphics card

If you know the motherboard details, you should be able to download drivers from the makers site.

IIRC the refresh rate for a TFT monitor is 60MHz or slightly higher - it's not the 85MHz minimum normally required for a CRT monitor.

If you right click on the Desktop>Properties>Settings tab>Advanced button>Adapter tab>click on List All Modes, the colour/resolution/refresh rates of which a graphics card is capable are fully listed.

You can click on any combination as required to highlight it and set it - ensure that Windows doesn't have to Reboot for the choice to become effective.

thanks to everyone who helped
ill be working on it in the morning
im sure ill be back with some questions

  athenrye 14:52 14 Feb 2008

hi guys
ive tried to fix it by checking the refresh rate
as stuartli sates, but the card says it supports 1680 x 1050 and has a true colour 60hz rate

the flicker goes away when you change the resolution down to 1280 x 768
but seems a shame to have this sreen and not be on the big resolution

  Stuartli 14:59 14 Feb 2008

It would appear that your card either doesn't support this higher resolution or the graphics drivers might need updating.

In any case, if your friend has poor eyesight, increasing the resolution will presumably not help him.
