You may use an HDMI / DVI cable to connect to your computer. Next if you have windows 7 hold your windows key and hit the letter "P" (for projector) this will allow you to bring on the multi-montior feature on your computer. Make sure to select the option that says EXTEND. Please note that when connecting a DVI device you must use the HDMI IN1 (dvi) jack on the back of your TV. you cannot use HDMI In 2.
1. Turn off your TV and all connected equipment. 2. Connect an HDMI/DVI cable or DI-HDMI adapter between the HDMI in 1 (dvi) jack on the back of your TV and DVI OUT jack on the DVI device. 3. Connect an audio cable between the DVI audio IN jacks on the back of your tv and the DVI audio jack on the dvi device. turn on the tv then turn on the dvi device.
Your laptop will need a HDMI output or a DVI output for HD video. If your laptop only has a VGA out the your tv will need a VGA or DVI input. You could use a vga to dvi adapter if your tv does not have a vga connector. They do have a DVI to HDMI adapter but there are a couple of problems with that. One you will not get the sound and the TV will only obtain sound from HDMI cable when connected that way and Two the TV will have problems processing the signal from the computer due to the HDMI will only process the HD signals at certain formats and the computer video can send out many different signals. I tried and I could not get my tv to process the signal so I got a video card that has a HDMI out and my blu-ray player works great.
Im no expert on the subject, but I use my L37 for a monitor, and use just the vga adapter. It works good as a monitor, and both dvds and my hdtv wonder tuner card look great through the vga connection. They do make adapters for dvi to hdmi. Although, hdmi also carries sound, but you wont get that out of your dvi output from your card. So you might not have sound when using that connection, as your tv may not look to the headphone type jack used for sound imput from your computer when you select the hdmi source on it. If you have speakers already connected to your computer you may not care. Also if you have a 720 p Vizio, 1366x768 is the highest resolution you are going to get out of it anyway, if I'm not mistaken. I'm Not sure why you would need 2 connectios to the same monitor either. I posted 1 link below because they had several dvi to hdmi adapters. Hope that helps.
It may be the top of set box.. Most times the sound and picture are auto detected by the set when HDMI is used. Both sound and video are carried in a HDMI cable but not with a S video cable. Try another HDMI cable *** dont buy the expensive one the tv don't care if they cost $125 or $25.
This may not be DVI issue.
I connected DVD player HDMI ----> DVI ( Dell W3000) LCD TV.
Later I found that Dell TV version of DVI does not support HDCP protocol ( High Definition Content Protection protocol). So I could not play HDMI to DVI movies from my DVD player instead I use Y Pb Pr -- this works ok.
Hope this helps... I am not use PS3 enforces HDCP - I assume Sony linked with Sony Pictures would enforce HDCP on HDMI cable.
