Hi all ... have just bought some acer exensa 5230's downgraded the first one to XP put on SP3, Klite codecs etc as I normally do ... when trying to play certain DVD's I get the message
Your display does not support protected content!!
Ive googled and it seems lots of people have the same problem but no answer
Anyone seen this one before?
Does it have an external HDMI port? Its not to do with the HDMI-CP (content protection) is it? Check for a driver for the display on the Acer site or download from the original chipset manufacturer.

What's the DVD you're trying to play? Maybe those DVD's have protected content that needs a certain codec to run.

Just to test maybe see if VLC can play those dvds ( VLC media player - Open Source Multimedia Framework and Player )

I think I saw this a while back, if I remember 'rightly' the solution was to use something else to play it (PowerDVD or VLC)

Thanks for the input people ... Ive been experimenting with various settings and it seems that these laptops will play the video on the laptop screen or the projector but not both at the same time ...!!!!
All of my others in the school will !!
On a different tack
I got a message on the screen that the optimal res for the laptop is 1280x800 .. I set it at that but the projector threw a fit at that res !! The laptop screen looked great though !!!! So its back to 1024x768 !!
It sounds as though the projector doesn't support resolutions that high but as you say, running at 1024 x 768 should be perfectly fine for DVD viewing.I got a message on the screen that the optimal res for the laptop is 1280x800 ..

Most laptops in my experience do require you to switch the video output, normally using a combination of fn+F5 for example, then again to reverse. Desktops are definitely better for this application as it just works with a hardware splitter
cant remember the name of the utility exactly but I know there are a few out there if you google for it you should be able to find one that works that will allow you to set the projector to one resolution and refresh rate and the TFT / monitor at a seperate res and refresh rate
You can do this in Windows anyway?cant remember the name of the utility exactly but I know there are a few out there if you google for it you should be able to find one that works that will allow you to set the projector to one resolution and refresh rate and the TFT / monitor at a seperate res and refresh rate
Yeah you can do that in Windows.
Isn't this a software restriction anyway?
A lot of DVD software will only allow you to view the DVD on the primary monitor, I think this is because they think that the secondary monitor is almost always going to be a TV or a projector and you wouldn't use one of those unless you were showing it to a big bunch of people (which infringes the license) would you? (!)
Of course, it's up to you which screen you set as the "Primary" so that sort of gets around it.
I normally tend to use the util as a lot easier as gives you a pop up menu to select which monitor and then from there which resolution / refresh rateOriginally Posted by Michael

Yes there probably are utilities you can use within the notification area, but Windows does allow it too by right clicking the desktop. Not sure if this would still work if you removed/disabled access to Display Properties in Control Panel?I normally tend to use the util as a lot easier as gives you a pop up menu to select which monitor and then from there which resolution / refresh rate
Which was why I suggested the utility because it can still use the windows API calls even if the display thing is disabled via GPO and if they have enough access rights to the utility it should still allow them to change the resolutions on the monitor / projector.
Worth a shot at least - I know when I was at uni they disabled you from opening or using the cd player in windows etc and had my own one that I made in borland c++ from a tutorial and when I ran that it worked but yet when trying to open the windows in built cd player at the time it refused to open ( obviously had to use the trick of renaming the exe to something that was allowed to run ie calc.exe ) but that was down to how they had configured GPO's at the time

Interestingly Ive never had a laptop that had a problem in this area !! They seem to have different ways of controlling the output as you say, some ignore the fnc f5 combo and want you to right click the desktop to get to a change menu. But these are the first that wont allow dual display when playing a movie ... Ive got some old acers that get a bit choppy when running both but they at least let the movie run ... we have them on the projector only and they are fine ... Maybe I got lucky with my choise of manufacturer !!It sounds as though the projector doesn't support resolutions that high but as you say, running at 1024 x 768 should be perfectly fine for DVD viewing.

sometime going to diaplay properties/settings/advanced/troubleshooting and reducing hardware acceleration to disable all but basic will allow laptops to display on 2 screens at once ive found in the past
