Re: Bad Live TV Signal

The native resolution of your TV is 1280x720 see the following.

Why it will not accept 1280x720@60hz over its VGA interface connection I do not know. Have you tried it?
I have an older generation (HL-P) Samsung 46" 720p DLP TV and I have no trouble using the VGA connection on my desktop or laptop using 1280x720 as a desktop and output resolution over VGA.

You certainly do not want to use a S-Video interface since it only outputs SD 480i images of your desktop so you get no actual HD resolutions.

You are seeing the 800x600 at boot time since that is the default resolution out of your graphics card before Windows is booted and changes the resolution to the setting you have selected for output.

Too bad you don't have a DVI output from your graphics card, however, if using the DVI interface the TV will overscan the output which makes use of PC applications difficult since the edges of the screen are cutoff.

My tv is a Samsung 46" DLP, model number HL-S4676S. In the manual it
states to use 1024x768 60hz, which is what I have it at now. If I try
to change that on the PC, the tv will respond with a "No Signal
Detected" error. The TV will change its resolution to whatever the PC
is set at. During boot up on the PC, the TV will switch to 800x600
resolution. With a Windows screen, the resolution looks pretty good,
and in MCE the menus look great, with OTA high-def channels look
great, as wel as DVD's through MCE.

As for connections, I have RCA jacks for sound from my DISH receiver
to the PC and then digital out from the PC to my theater unit. I have
S-video from the DISH receiver to the PC and then VGA cable from my
tuner card to the TV. I have tried coax connections from the DISH
receiver to the PC and that was even worse.

During MCE set up, the wizard will not recognize the OTA antenna and
the DISH receiver together. If I it will only recognize one or the
other but to be honest, this is the least of my problems. I can still
get HD local channels through another connection to my tv. I'd like
to get the video problem fixed. If I only get local channels in MCE
it's not worth it to me to keep my MCE machine....I'll use it as a
normal PC. To answer your question though, I get ABC, NBC, CBS, FOX,
and a few others. My signal is a little week but it works pretty
good. I only have an indoor antenna right now and will be getting a
larger more powerful antenna in the near future. I understand MCE
likes to have a strong signal which I suspect may be some of my
problem.

I've tried the WinTV app for Hauppauge and that program won't even
detect a signal from any source so I gave up on that route.

Thanks for the response.

Oops, the resolution section is confusing... must be too early in the
morning.

The tv's native resolution according to the manual is 1024x768 60hz.
If I try to change that either on the tv or the PC, I get a "No Signal
Detected" error. However, during boot up of the PC, the tv will
change or at least recognize 800x600. I noticed this while I was in
tv setup while the PC was booting up.

I'm not sure by your question of what interface I'm using. I have an
nVivia 6150 (yuck) video card and am using a vga cable from the video
card to the tv. That's the only option I have. I wish I had an S-
video out on my video card but I don't.

Thanks again for the help!
Don
