All About HDTVs as a PC or Laptop Monitor

I found this post on http://www.lcd-tv-reviews.com

Re: LCD TV as Monitor
I have a LC-45GX6U Sharp with a 50' (feet) component cable to connect to my video card and i have the resolution set to 1920 x 1080i. Works better than the image i get from some cable HD channels! Dvi or VGA will only go up to 1280 x 1024 so this was the only way to use the whole screen!

According to some users, the DVI input supports a maximum resolution of 1024x768 which is always scaled to the TV's 1366x768 widescreen resolution. There apparently is no way to force a 4:3 aspect ratio for the PC input.

Not necesarily true

A lot of the flat panels accept native resulotion over their DVI/HDMI/VGA input. This can be for testing the panel for dead pixels.

See this thread for more info.

From what I can tell, this 1080p TV only accepts up to 720p on the VGA input. Looks quite bad not being the native resolution.

Mine says only "up to 1024 x 768". It would not accept 720p or 1080i in PC mode. But it does take 1366x768.

On this TV there is a DVI-HDTV that the manual say is "not intended for use with personal computers. I cannot get a DVI plug onto it anyway!

I cannot get a picture on the tv. The windows screen prior to going to MCE 2005 is good rez. but right now no picture on the TV screen.

asus P5GL MX mother board with All in wonder Elite, and gigabyte gv-nx66l128dp.

I have had to use S video to connect but I do have a VGA to HDI plug?

Any advice would be appreciated.

There are various types of DVI - DVI-I, DVI-A and DVI-D. Please see the Digital Home FAQ "DVI/HDMI Information" (Under Help).

Is this confrmed and if so has it been tested on the HDMI and VGA connector?

When I briefly owned this model, I was using the VGA input (D-sub 15 pin RGB). It's maximum input resolution was 1024x768. What was really neat however, was that it was stretched to fit the widescreen and the Windows desktop showed no distortion except for being a little squat. Text was perfectly legible. But I returned it since I couldn't drive it at full panel resolution (1366x768) and there were other problems with black crush and dead pixels.

I recall that the Proview/MAG owners manuals confirmed this. But they seem to have a new glossy version which says nothing about connecting PCs.

My video card is an ATI AIW X600Pro.

Thanks for the reply!!!

That last bit of info just kept me from making the mistake of falling for the Canada Day Sale on the Proview 27 or 32.

I use MCE 2005 on my 3Gig P4 through a NVidia 6600GT component dongle.
My video card detects the set as an HDTV and can dual display in 1024x768 on my 19 inch monitor and 1080i on my HDTV with component connection at the same time. HDTV signals from my DVB tuner card come through at full rez and full screen on the tv. Overscan is adjustable with the video card's software driver bundle. The only downside is the black bars on the side of the tv with 4:3 SD programming captured with my hauppauge PVR-150 from my C Band system.

I am trying to connect a 50HP66 to a Dell computer using the VGA connector. With the PC set for 1024 X 768, the picture is in the middle of the screen with bars on either side. I expect this since 1024 * 768 is not a wide screen format.

The display has a setting WXGA when turned on allows for 1280 by 768.

When I turn on the WXGA feature the 1024 * 768 picture is stretched. Looks funny, but I can still read the display.

When I attempt to reset the computer to 1280 by 768, the screen goes black until the PC times out and reverts to 1024 X 768.

What am I missing? Is the PC timing out before the display can synchronize to the new format? As far as I can tell the refresh rate is always 60Hz.

Thanks

Have you tried the new resolution on a computer display?
Don't try sending anything to a TV before you confirmed it works on your PC monitor.
You might want to try on your monitor the Sony GDM-W900 driver.

It sounds like enabling WXGA just stretches the picture.
You want to send native WS signal to your TV and make the TV leave it as is.

Replaced the video card. Everything is working as it should now.

Has anyone tried hooking up their HTPC to the Panasonic TH-50PX60U?

It doesn't come with a VGA input so I'm unsure if its suitable for running Windows Media Centre.
