Windows 7: lose HDMI video when windows loads

lose HDMI video when windows loads

I have a mini computer (specs found here I have had this setup for over a year now with hdmi audio and video to a receiver, then on to 2 projectors. It has worked (except when nvidia or windows updates something) great until about a week ago. It now works fine on boot up until you get to the Starting Windows message. After that message the screen would go back into standby mode. I figured it was another video update gone wrong, so I booted to safe mode and rolled back the driver. No luck. I took the computer to a regular monitor and plugged it in with hdmi. Same problem. I attached the monitor to the the dvi on the computer (using a dvi to vga adapter) and it boots up to windows fine. I then started the computer with hdmi connected, waited for the Starting Windows message to go away and the screen to go to standby, then switched back to the dvi port, and windows was loaded. So out of all that I gathered that the dvi port is working fine and the hdmi port only works until Windows loads.
Since then I have updated the graphics card with the latest driver from nvidia (v8.17.13.142), searched the BIOS for a setting to change (currently on AMI 080015 A02), I have tried to find a BIOS update (with no luck), tried to update the chipset (didn't seem to need an update according to intels automatic scan feature), and uninstall the video driver and allow windows to load its own driver.
I now ask for help with this thing because I don't know what to do next. I have not really been able to find a place with drivers for this machine. I don't know that a reinstall would fix anything, and I haven't tried since I can't find a good place for drivers and I don't have a Windows 7 Home Premium setup disk. Any ideas??

Okay delete the COLOR things and I might be able to read what you are writing.



PS: Probably the driver that set the wrong resolution when connecting the HDMI
Disk is never a problem, just go to a store and ask for a disk copy, or if you are lazy, download the disk and put it on a USB drive.

Sorry about that. Not sure why it came out like that.


I have tried changing the resolution while on hdmi and then moving back to hdmi. It still does not work.

Three suggestions.

1. Trying loading the Windows system drivers in the Safe mode, reboot PC.
2. Check the power settings (advanced) and make the appropriate settings.
3. Uninstall the current Nvidia video drivers and only use the Jetway drivers.

I tried loading the windows driver in safe mode and no luck.
I'm not sure what power settings I should be looking at specifically, but they all look to be what I would normally set on other computers.
I wasn't able to find any jetway drivers when I was looking around on the web. I did forget about a driver disk that came with the computer though. I will try it in the next day or two and let you know how it goes.
Thanks for the help...

Sorry if this seems obvious to you but have you checked the display settings? Right click the desktop and click Screen Resolution while the computer is connected to the projectors. Make sure the settings are correct (I assume you want to duplicate the displays), including the resolution settings. It wouldn't be the first time a setting like this was changed during an update.

I know this is late, but I just came across this post again (Iguess I forgot about it). I ended up reinstalling the computer after I found a setup disk for it. I managed to find drivers on different websites and got it back running. All is good after the reinstall.

Thanks for the help and sorry for the late reply..
