- Playing back DVD on PC: black picture on external screen?
- Posted by Wondering on October 19th, 2004
I am experiencing a stange problem when playing back DVDs on my IBM
ThinkPad T41 laptop with a digital plasma screen attached.
Movies play fine on the laptop's LCD matrix or on an external LCD
digital flat panel, connected thru a DVI port. However, if I connect a
digital plasma monitor to the same DVI port, the WinDVD window appears
black on the plasma screen (no matter, in windowed or full screen
mode), however the laptop screen shows it fine at the very same time.
The rest of the Windows desktop and apps is being shown just fine on
the plasma.
Software: WinDVD 4.0 DXVA
Video Adapter: ATI Mobility Radeon 7500
OS: Windows XP Professional
External LCD Flat Panel: ViewSonic VX710 (via DVI)
External Plasma Flat Panel: Sony PFM-42X1 (via DVI HDCP-enabled)
Any clue what might be causing this? I suspect this can be related to
the fact that my plasma's DVI input is HDCP enabled, but the whole
issue still makes no sense.
TIA!

Try again after switching on Theater Mode in the Overlay
(Clone mode options) settings.

Thank you for your quick reply, however I'm sort of lost here: when I
open the Overlay tab, everything is grayed out there, except for the
"Clone mode options..." button. If I click it, it shows another
disabled dialog withthe following note:
"These overlay settings are only available in dual-controller Clone
mode, and not single display or extended desktop configurations."
Not sure how I get to that Clone mode, or even what it is...

It probably means you have extended your desktop onto your second
display. Uncheck that option. Take a look at this picture:

Have your external display plugged in before you do this, or reboot after
you connect the second display. If your driver is the same as my ATI AIW
7500 desktop card, the following should work. Right click on your desktop
and choose "properties". Click on the "settings" tab and go the the
"advanced" button. Now click on the "displays" tab. See the little blue
boxes below each monitor? Make sure that the one with the DOT is selected
for each monitor that is connected. Hope that helps.

Nope. I was aware of that one. I use a single display/desktop
configuration, and my external screen shows the same picture as the
laptop's panel...

I have the T40, and it is similar. Try switching to just the external screen
with Fn-F7.

Try the changing the colour depth. Just upgraded my desktop to LCD using DVI
from CRT and had the same thing happen except green. Changing from 16bit
color to 32bit colour fixed it.

It did, thanks! Looks like a DVD can only be played on 1 monitor at a
time (the primary one). I am not sure why, though. Both WinDVD and
Windows Media Player behave in the same way. It could be a content
protection issue, however I didn't see any difference between playing
back a retail DVD or a decrypted copy with CSS/Macrovision/region
removed. Go figure...

With Theater Mode you can play it on both displays. Desktop users can
enable Theater Mode. Apparently you can't, so maybe it's a limitation
of the Mobility drivers.

You're, most likely, correct. I'm gonna try with my desktop box
tonight. However, that one has GeForce FX 5700 Ultra, so the situation
will be different.
By the way, how is your TV connected? Via DVI or S-video?

I'm sure it's possible with a GeForce card as well, but it's not called
Theater Mode. I think this website explains it:
nVidia GeForce: http://www.weethet.nl/english/video_pc2tv_nvidia.php
ATI Radeon: http://www.weethet.nl/english/video_pc2tv_ati.php
I use one of those PC to TV Senders.

Good enough for DivX/XviD. DVDs look better in a standalone DVD player.

I had the same problem with my Thinkpad T40. When trying to run
2 screens (the LCD and an external), the DVD overlay would not
show on the external screen. When I made the external display the main
output (with no LCD operation), the DVD played correctly. It
has something to do the overlay and how memory is addressed so it
can't be displayed on both at the same time.
Your mileage may vary.
