How do i get my resolution up to 1080i?

I have a Vivitek 56" DLP HDTV, which I've had for a few years now. My cable box has always been connected with component cables to the COMP1 input. I just recently realized that I was only getting 480p resolution with this connection. I always thought the picture quality was decent, so I never thought much about it even though the tv is capable of 1080i.

I'm now using an HDMI to DVI cable connected to the DVI input on the tv, but I'm still only getting 780p resolution. I also noticed that I can no longer change the widescreen format with this connection. It's set to "dot by dot" and on most of the non-HD channels the picture doesn't fill the entire screen. When I was connected with the component cables, I had options like "stretch", "s. stretch", "zoom" and a few others that I can't remember.

Does anyone have any suggestions on how I can the full 1080i resolution and maximize this tv's potential.

Thanks!

    I have a Comcast cable box that does say HDTV on the front of it.

    I'm not so concerned about HD, but I have an RCA HD monitor connected via HDMI to the TV's DVI input. Since I did this, ALL the heads on both HD and standard channels are chopped off. Ideas?

    When I had it hooked composite to the TV, the format button on the remote let me change the size of the display to something that would correctly fill the screen, like 4X3.

    Thanks!

Viviteck 56''in.HDTV DLP TV. replaced with a new lamp bulb since I replaced this the tv wont come on only the sound for about 5 seconds then tv is silent again. any tips, Please.


The first thing to check on any TV that has a replaceable lamp is to make sure the lamp door is back on and seated correctly. You also need to make sure that the lamp is seated all the way in. The lamp door and in most cases the lamps have saftey switches they have to activate for the TV to work normal.

Samsung DLP 56' TV turns itself off when I initially turn it own. (I turn it on, then it shuts off for approximately 5-10 seconds and turns back on. Sometimes it does it a couple of times before it stays...


The problem is with the ATT UVERSE HDTV BOX and not the Samsung DLP TV. There is an inherent problem with the ATT UVERSE HDTV Box when using a HDMI cable. This was verified by the ATT UVERSE Technician.
