This may not be more problems, just more of the same. I have now had a bit more time to investigate the problem.
Our church computer is running Win XP Home with SP3. It has an Intel Celeron 430 CPU running at 1.8GHz with 1 Gb RAM. The video card is an Nvidia GeForce 8400 GS with dual ports, one running the monitor the other the projector. The projector is a fairly old Epson EMP-7250. With the display set to cloned screens powerpoint runs well.
I set the display to Extended mode, with the projector as screen 2. I open openlp (version 1.2.7) but when I go to Options|settings|Display Settings the drop down box only shows the single monitor it does not display the projector as an option. However, Win XP when extending the desktop does see the projector as expected.
I'm sorry is starting another thread creates a problem, but the existing threads seem to be getting a little jumbled.
Hi Greg, are you 100% sure you started OpenLP /after/ extending your desktop?
Yes absolutely positive. Having posted this problem before and followed the other threads I was most careful.
I am using on my home machine, and also on the church machine, video cards (both nVidia) with dual ports - not two separate video cards - might this be part of the problem? It seems strange that XP recognises both devices correctly, so presumably the device name is being returned to the OS correctly.
Outside of OpenLP does the 2nd display work as expected? Let's make sure the issue is in OpenLP and not in your configuration..
In as much as we can show a cloned powerpoint display, it worked, but I admit that we have similarly been unable to use the powerpoint presentation mode. Again it seems that powerpoint doesn't see the second display device. I have the same problem with my own desktop machine with powerpoint though for normal Windows use I can use the extended screen for my use of Photoshop.
When in cloned mode, there is no second monitor. Your second monitor is a clone of your first, and thus the operating system simply outputs on the secondary monitor what is on the primary. You need to set your desktop to extended mode for a second desktop.
See my first and second posts - when trying OpenLP I have always been in extended mode, however, this is not recognised by OpenLP or PowerPoint, I don't know where to go to try and settle the problem.
It sounds like your problem lies somewhere between Windows and your display drivers. I'm afraid the developers generally use Linux, so we're none-the-wiser to your problem.
It might be worth checking your BIOS settings too, when booting your PC. Make sure there isn't anything odd in the display configuration. Although I am clutching at straws there!
Well... while we are clutching at straws I'll throw my straw clutching in also. Might be worth checking your driver's software. Sometimes that has caused me an issue or two because windows telling one thing and the NVIDIA propritary program be telling something else.
Thanks Guys, I have a feeling it's to do with the nVidia card, I have recently downloaded what appeared to be the latest drivers without effect, but because I have the same, or similar effect with PowerPoint I guess it's not OpenLP, I just hoped you might have had some inkling as to the solution. Will persevere.
