I have a computer with HDMI output and my Scenium has HDMI input but I get no picture when I play movies on my HP 9700 computer that I would like to have displayed on my RCA Scenium. All connections seem complete. Am I attempting the impossible?

If your TV has a VGA input you can enable monitor 2 on your laptop and use the external vga output

If your TV has an HDMI input - connect up the computer to the TV with an HDMI cable.
Select HDMI on the TV inputs.
Play the DVD on the computer, should appear on TV is Input is set. Sound may be a fiddle ~ check you PC sound settings if there is none.
The computer will usually show a blank screen when the HDMI is going elsewhere,
Good luck

sounds like input problems, if its working with your BR hit the source or input button on your remote and toggle the inputs until you find your cable input its probably going to be hdmi or component

Did you try changing the audio output on your cable box to hdmi? If not please do so.

does your computer graphics card have a hdmi output on it? i had a same problem the coverter input will not let sound though it u would need a hdmi output from the computer or need to connect a separated sound output as the form of speakers from the computer itself, i mite be a problems with drives, try updating the graphics card drives. this mite solve the problem as well. hope this helps

Are you sure you mean an input? If it's a laptop, it shouldn't have any video inputs. The pavilion 9700 has the same shell as a few other pavilions, but the 9700 was never designed with an HDMI port.

You probably need to get a composite video output card for your computer. Actually, I've seen many cards that have both a composite video output AND a DVI output port on 1 card. The DVI output will give you a noticeably sharper picture than composite video, but you need to check if your TV has a DVI or HDMI input. (If it was manufactured after 2000, it probably does.) If you TV was manufactured after 2006, it probably has 1 or more HDMI inputs instead of DVI. You can buy a DVI to HDMI converter cable. That takes care of the picture; to get sound to the TV, you will need to connect separate sound cables to your TV. Your computer needs to have a line-level output jack on it's sound card, and you will need to get an adapter cable (from Radio Shack) to convert the stereo mini-plug to 2 RCA type plugs to plug into your TV. And that should do it!

HDMI ports 5 and 6 on the back of tv no longer are working. (We had a series of thunder storms so don't know if that is how they got damaged or if it was something else) but moved HDMI input cable to HDMI port 4 on tv and everything is working again. Service call placed for warranty service on tv to repair bad ports.
