Hi using full hd TV as monitor but flickers even when refreshed. It also has the annoying habit of not recognising any changes made when rebooted forcing me to reconnect the old monitor and follow the whole procedure again. Embarrassingly I am using and old dell optiplex gx620 whilst awaiting my new comp. Please help

You haven't said what windows version you are using.

Sorry I am using vista ultimate

Has Vista installed a driver for it or does it call it a generic TV?

Thank you for your replies. I have now updated to windows 7 on a Packard bell and the t.v. is still flickering like mad. Does this mean it is a t.v. fault? It is only when I am using my computer on it as it is a perfect picture when on x-box or DVD.
Thank you

Try different resolutions and refresh rates on it.

Perhaps your TV has a dried out capacitor then?!?

Is your system is not compatible ?

May be your system is not compatible, it would be better if could go through the manual.
