Sager (np6856) Showing wrong display, 144hz Monitor limited to 60hz..

Hello, I have recently reinstalled Windows 10 x64 Home edition. I was able to play 144hz on my Internal LCD Monitor just fine before, and I am now limited to 60hz (Using CRU I can get 75hz Max)
My monitor is being displayed as a LGD05E5 "LG Display" Monitor, Which is limited to 60hz as shown here
http://www.panelook.com/LP156WF4-SPD1_LG Display_15.6_LCM_overview_19846.html




This is what my device shows


I have Switchable Graphics (Working)
Nvidia Geforce 1660 TI and Intel UHD 630 Integrated

I have been unable to find the correct monitor after atleast 48 Hours of online searching, I am unable to find the correct BIOS to flash (Was hoping to find a modded one)

I would really like to get back to 144hz if anyone could help.
I have dual booted Linux and have used the EDID tools available (Such as Read-edid, xandor) and it shows the correct resolutions and refresh rates, was also able to get the raw edid (Hex) but haven't found a way to decode it or import it to windows. I have given up finding a solution on my own, and I have honestly spend days trying to resolve this.
I have reinstalled 3 different versions of windows,

Download a fresh image and try again? Make sure your intel drivers are up to date too.

 

I have tried 4 different windows versions, installed all the drivers fresh on install without internet enabled. Would reflashing the bios fix this? Maybe updating the bios? I haven't had any luck with finding a bios whatsoever. Was hoping to find someone else with the same LCD and get the EDID from them but, no luck. Any suggestions on how to get the EDID from linux and save it as a bin / dat file so I can port it to windows?

 

This should all be embedded in the panel, sounds like the firmware in it has been corrupted.

 

Any suggestions on how to fix? Also do you know where I may be able to get the bios firmware to reflash?

I managed to get some more information through edid-decode on linux

Going by all that data its a 60Hz display.

So unless you are mistaken, or by some way you changed your display, it was always a 60Hz display.

Contact your seller and ask him what exactly was mounted on you laptop, or check your invoice, would be pretty strange to loose one or two lines of display resolution/refresh rate and nothing else on the EDID, the fact that you can't OC it over 75Hz is also a bit indicative.

 

Did you have the panel repaired at some point?
