Little-Miss Posted January 26, 2012 Posted January 26, 2012 Hey, here's one for ya... Projector and laptop work happily for weeks. Different member of staff attaches their laptop to projector, dont get on straight away but with some gentle coaxing there work happily together. Original teacher plugs her laptop back in, projector is no longer speaking to it. Laptop, knows projector is connected. So it will do dual display but nothing appears on projector. Thats until you load something like a browser or press the start menu...it suddenly springs to life (in a fashion)...its got a distorted shaky bit on the image and then its flicks off again and back on again and off again. Close said browser or start menu and the image goes off completely... I've updated the graphics driver that hasnt helped. Rebooted with and without projector attached to laptop....only thing i havent tried is swapping VGA lead. Bamboozled...
Little-Miss Posted January 26, 2012 Author Posted January 26, 2012 You know, thats one thing i didnt look at....my gut says Sanyo.
CESIL Posted January 26, 2012 Posted January 26, 2012 You know, thats one thing i didnt look at....my gut says Sanyo. Tee Hee...you obviously have had similar experiences to me...
Little-Miss Posted January 26, 2012 Author Posted January 26, 2012 Any ideas? Gonna test it with a monitor tomorrow...
mac_shinobi Posted January 26, 2012 Posted January 26, 2012 refresh rate , screen resolution and with it being a laptop if it uses any graphics card utils ie intel, ati or nvidia then use the relevant utils to adjust / change the refresh rate / screen res etc as these utils normally over ride the settings that you set through windows as they normally have an exe that launches with windows and over rides the windows settings. ie the intel one I think is igfxpers.exe 1
Little-Miss Posted January 27, 2012 Author Posted January 27, 2012 I've fiddled with refresh rates and resolutions. Its currently attached to my monitor, again, it knows its there, does a little ding dong when attached, and as far as its aware it is displaying on the external monitor.... Please dont tell me somethings knackered. I have no more money! lol

If I remember correctly there was a hidden setting on one projector that you had to adjust either the input source or type from vga / svga / etc which fixed the issue or something trivial setting wise which I think you could only get to using the projectors remote control through the menu system, took us a couple of hours of fiddling with all the settings to find it.
Oaktech Posted January 27, 2012 Posted January 27, 2012 also, see if you have a signal phase adjust and a pixel clock setting on the projector as playing with these can fix some of these issues... 1
