I have a Dell Inspiron 720 with an HDMI port in the back. I have been using it with my Samsung TV to watch movies on. Now it no longer works. I ordered a new cable but it keeps telling me to check power supply, cable connection, and the make sure it's on the right setting. I have 2 hdmi ports on the back of my TV but still come up with the same error condition when I switch them. It appears the port in the computer is not working anymore. I have tried everything but nothing works. I am running an ATI 4200 which is on the motherboard. Can this be fixed or would I have to buy a new graphics card to get it working again. I did swap the cables but still get the same results. Does anyone have any ideas because I have run out of them???
The only way to fix it is to buy a new motherboard, do yourself a favor and buy a new video card instead, Dells are not worth fixing. But if it`s under warranty well then that is a different story.
If that`s a laptop then your ONLY option is to replace the motherboard, very simple to do.
