How do i change my computer resolution 1920 x

[kenswansea]

Hello,
When I hook up my PC to HDTV, I get an "invalid signal" message. My tv requires a 1920 x 1080 resolution, but my computer only goes 1280 x 1024. I can only use my old monitor now. Thanks

Hi. You should hook up using an HDMI input to get HD
