You shouldn't be able to see a 25Hz refreshed screen ...

by OldER Mycroft In reply to my computer turns to 25 h ...

At best it would resemble an old Charlie Chaplin film, stuttering it's way through any on-screen movement.

Even an old standard PAL CRT TV runs at 50Hz (with the NTSC system producing a 60Hz refresh rate).

Most movie projectors advance from one frame to the next one 24 times each second. But each frame is illuminated two or three times before the next frame is projected using a shutter in front of its lamp. As a result, the movie projector runs at 24 frames per second, but has a 48 or 72 Hz refresh rate.

I've just checked on my old white box that runs as my media centre, with an old 17" CRT powered by an equally old Intel 82845G controller - it can only offer a refresh range between 60Hz to 85Hz.

Where are you getting this reading of a refresh rate of 25Hz ??

What are you saying here?

by OH Smeg Moderator In reply to my computer turns to 25 h ...

Are you saying that when you first start the system it is displaying at 25 HZ or that when Windows opens and is loaded fully the Refresh Rate is set to 25 HZ?

If it's that the Screen Refresh Rate isn't sticking after being set the most likely thing wrong is that it's being set too high beyond the abilities of the Video Card to generate the Picture. So that when the system is restarted the defaults back to the slowest that is viewable.

If that's not the case here you'll need to tell us what OS is in use, what Hardware is being used and other things like that.

OH if this is a NVidia Video Chip Set it's possible that has failed and is causing the problem as well but it's not all that common.
