Hi there iam tryin to install a second monitor (sony kdl-26U300) this has been connected via a 5M HDMI to DVI CABLE w/FERRITE the resolution is set to 1366*768 and 60htz rr. When this is the secondary display (as an extented desktop), it seems to be ok but when i make it the primary one(which is what i need it to do) after a few mins the display starts to fade and go blocky then freezes altogether. There is no warning from my graphics card to say it is overheating so i dont know what i'm doing wrong, as you can imagine im very concerned for both my monitors and my graphics card, what do you recommend ?

Hi bodingtonsboy, and welcome to Geeks To Go!

Can you answer a few questions for us so we can better help you?

What graphics card(s) are you using? How is the second monitor connected?

Also, graphics cards don't typically warn you when they are overheating.

Try disconnecting the old monitor and see if the problem continues.

And just use the one monitor ? and do you know what the highest temperture my graphics card should reach at a safe level ?
