Hi,

I've recently upgraded my CRT monitor to Toshiba's Tekbright 60A
(bought it off a friend), however there seems to be a bit of a problem
when playing DVDs on it now. The picture tends to break up into
multi-coloured blocks momentarily, then recovers and works fine, and
then again it has bits of those multi-coloured bricks popping up again.
And this continues pretty much throughout the DVD run. Watching a
movie is literally becoming a nightmare with this problem.

OS : Windows 98
The very same DVDs played fine with the CRT monitor, the only thing
thats changed is the monitor! And apparently Toshiba has stopped
manufacturing any more of these models (i.e. Tekbright 60A).

Will appreciate any advice I can get.

Thanks.



P.S. : I've already posted this message at the following groups, but am
still waiting for a response

I would think that this is caused by an incorrect refresh rate.

Thanks alot. I am still slightly confused about what to set the
refresh rate to. Its currently set on "Optimal" (under the tab
'Adapter'). When I try to set it to 75Hz, it pops up with a warning
that its a custom setting and an incorrect setting will damage the
monitor if the monitor can't support it. Now I've looked up the
technical specifications of Tekbright 60A and this is what I've been
able to dig up :

horizontal refresh frequency : 24-60 Hz
vertical refresh frequency : 56-75 Hz

So just wanted to ask, does the Refresh rate on monitor settings
corresponds to 'horizontal' or 'vertical' value i.e. should I try
setting it to 60 Hz or 75 Hz?

Thanks.

have a very old monitor it will give you a warning if the refresh rate
is set too high. Old monitors may be damaged by too high a rate.


Some good info about refresh rates, etc. here:

Thanks to everyone for all their advice.
