I swapped out my 980m (P750ZM) with my 675mx (P170EM). The 675mx still had the same issue when installed in the 750ZM, and the 980m didn't have any issue at all. So I have figured out that the issue is the P750ZM's mainboard. Guess I know what the next thing I need to work on will be. Thank you Prema and Aaprcard for all of your help in diagnosing this issue.

That didn't do anything either. I am starting to think my GTX card is just trashed somehow.

I have done the vBIOS re-flash in Win 10, should I attempt to re-flash the vBIOS in Win 7?

Here is a strange one for you Prema. When I installed Win 7 and all the drivers, my notebook didn't even recognize my internal display, nor did my notebook even show the internal display in Device Manager or the Nvidia driver settings. It only showed what was connected to the HDMI connection. - - - Updated - - - Tried that several times so far.

Pci\ven_10de&dev_13d7&subsys_75001558&rev_a1 pci\ven_10de&dev_13d7&subsys_75001558 pci\ven_10de&dev_13d7&cc_030000 pci\ven_10de&dev_13d7&cc_0300

Did a reset and a re-flash and still will not show the BIOS screen on the internal notebook screen. Any ideas?

I tried to upload the file but the system wouldn't allow it. How can I upload it? Here you go, .txt to .bin and you are good Sorry Prema, it has been a long week and i"m tired of thinking lol. P750ZM.LP156WF4-SLB5.txt

Ok,backup created. Here is the info from the program you linked to me. Display Info.txt

That didn't do anything. The system still doesn't show the BIOS on the internal screen or give me control over the screens brightness without having an external screen plugged in. Do you think I should just reflash the vBIOS?

System BIOS is 1.03.15PM v2 vBIOS is 84.04.22.00.F1 Here is the spec sheet for my display. I was not the original purchaser so I donot know if this is a G-Sync display. http://www.datadisplay-group.com/fileadmin/pdf/produkte/Displays/LG/LP156WF4-SLB5_Datasheet.pdf

Does anyone know where I can get the Firmware/EDID for my LVDS monitor to correct this issue? Model is LG LP156WF4-SLB5

Yes that is correct. My screen is completely black until Win 10 loads the drivers and then my screen will come back on. The other strange issue is, that unless I have an external display plugged in when I boot the machine I have no control over the screens brightness. So the screen is at 100% brightness and I CAN NOT turn the brightness down without the external plugged in during boot-up.

Hello all, I just read where the Precision X is bricking the EDID in the screens. I had had the EVGA X on my machine (Mythlogic P750ZM) with 980m. The machine self rebooted and now I can not see anything on the built-in screen until Windows loads the drivers. I can output through HDMI and see the BIOS load screen. I am running Win 10 Pro. In device manager it shows my display properties as “Generic NON-PnP Monitor. What "if anything" can I do to get this screen back to running correctly?
