I have my laptop hooked up to a PC input on my 55" HDTV, the tv is 1280x720 but when im running that exact resolution on my laptop, the eges around the output video has been cut... it happened on another 32" as well, with a different laptop..

I should be able to view full screen full res from a laptop on an hdtv, right? What setting am i missing?

On my Toshiba 47" LCD when I run the media PC at 1920x1080 it does the same thing until I set the TV display mode to 'Exact Scan' rather than Wide or Zoom etc.
Not sure if your TV will have the same option.

The other thing you can do is check the laptop display driver settings as the is usually some sort of overscan setting you can adjust so that the picture will fit.

It might pay to check the TV manual to see what settings are supported.

What are you are describing is overscan but this is normally an issue that you only encounter with a HDMI / DVI / Component / Composite input rather than VGA.

A regular TV signal is roughly 5% bigger than the screen so "overscans" the display. If you use a HDMI / DVI / Component / Composite input you normally have to make adjustments to your display driver to compensate for this and it's a normal issue.

Most TV's don't overscan the VGA input and this should display full size. It would pay to check the resolution and refresh rate you are using is one supported by the TV.

Cheers for the replies. The native resolution of my TV is 1280x720, that is what i have set the output resolution on the laptop to.. I can see the whole output video now but there is still bars around the side and top, like the picture has been shrunk a bit.. how is this possible if the resolution is set to the same as the tv?? Shouldn't it cover the entire screen seeing as it is the proper res?

You really do need to look at the manual and check for the suggested settings.

My laptop has the NVIDIA Control Panel, and it allows me to adjust the size and position of the output from my laptop to my TV.

Not sure if your one can, but just another tip.

I have a similar situation on a 24" monitor I have recently bought.  Native resolution is 1920 x 1200.

My laptop has the usual Intel Integrated Graphics so I set the resolution to 1920 x 1200 to match the panel -- well that was my theory anyway...

However, the monitor says the actual output is 1600 x 1200, not 1920 x 1200 as the laptop says.  It appears to me that the settings in the Intel driver are wrong, because the AR of the picture is definitely 4:3 with the full height of the monitor being taken up, but large black areas to each side.

I had a fiddle with the various options and the best I could come up with is 1920 x 1080 which gives a very small black border around each side of the picture, but the AR is correct and it's just wonderful to have such a large desktop.

When I get my desktop PC rebuilt with a new Core2 Duo CPU & motherboard in the next couple of days, I will have a play with that, and see if I can't get utilise the full capability of the monitor.  It has a separate PCI-express Nvidia Graphics card, and hopefully should be capable of outputting a genuine 1920 x 1200 resolution.

Maybe you will have to compromise as well, and just set your laptop to the resolution which gives you the largest possible desktop, while retaining the correct AR.

The native resolultion of your panel will actually be 1366x768, so inputting 1280x720 is slightly smaller than the displays resolution, and hence you will get a slight postage stamp effect.

If my plug my laptop into my Bravia the laptop automatically changes to 1280x768 (From the 1280x800 it is normally set at). I get very small black bars to the left and right as the 1280 across is slightly less than the panels 1366 pixels. I can however set the TV to stretch the picture to fit the screen, which still looks absolutely fine.

My server 2003 box which is sitting behind the TV outputs 1360x768 which is only 6 pixels off the panels display, and looks very nice.
