713833 2008-10-22 00:30:00 A friend of mine has an LCD TV, a Philips 42PFL7422.

As the title says, it can display 1080p from his PS3 fine but can't do 1920x1280 from his PC properly.

Both are connected with HDMI

The PC image can display, but it falls off the sides of the screen, as if it were a CRT with too much overscan. There is no auto adjust feature for the input because it's HDMI.

Copied from the spec sheet here (www.p4c.philips.com):

Supported Display Resolution
• Computer formats
Resolution Refresh rate
640 x 480 60, 67, 72, 75Hz
800 x 600 56, 60, 72, 75Hz
1024 x 768 60, 70, 75Hz
1280 x 1024 60Hz
• Video Formats
Resolution Refresh rate
1280 x 720p 3Fh
1920 x 1080i 2Fh
1920 x 1080p
640 x 480i 1Fh
640 x 480p 2Fh
720 x 576i 1Fh
720 x 576p 2Fh

Does this mean it can't support 1920x1080 from the PC as it's not in the list? yet it's in the 'Video Formats' list?

What is the difference between their "Computer Formats" and "Video Formats"

What's up with the "Video Formats" refresh rates being displayed as 2Fh etc

713834 2008-10-22 00:39:00 you should still be able to toggle overscan on/off on your TV's settings i think?

This fixed a similar problem for me.

There is no overscan option

713836 2008-10-22 01:45:00 My guess for the computer vs video formats is that computer formats are for the VGA port. As for the overscan-like stuff, some manufacturers continue to use overscan, and since it's connecting via the HDMI port, it might be forcing it, whereas the VGA port might not do overscan. What happenes when you drop the resolution? ubergeek85 (131)
713837 2008-10-22 03:09:00 The graphics card for the PC should have options for adjusting the overscan etc.
I have seen the option with ATI and nVidia cards.

713838 2008-10-22 04:54:00 I have a similar problem - both my sister & my parents have the same 42" panasonic plasma TV connected to their computer through a VGA cable. The TVs can do 720p through games consoles, but not through the computer.

The "Computer Resolutions" are all 4:3, not widescreen.

I haven't got round to buying a long VGA cable for my 42" LCD TV, so I've got it connected to my computer via component cables, and that has no trouble with 720p.

If overscan fixes it, let me know where to find the option in the nvidia control panel (if you have a nvidia card).

713839 2008-10-22 05:19:00 Problem is, there is no overscan option in the nvidia controls either (by default)

Though you can add an adjustment option with the following:

forums.nvidia.com
nvidia.custhelp.com

But the end result is the image doesn't look great.. might work for you though
