Alienware m17xr4 with lgd02c5 panel + GTX970m 6GB Display recognizing issue

[Vladimir]

Hi Guys, may be someone could give me a good advice...

The system:

Alienware m17x R4 with 120hz panel form r3 (LG - LGD02C5)

Bios Dell A15 (Also tried unlocked A11)

Now installed GTX 860m 4gb (Kepler edition) works with no issue

Bought GTX 970 6gb Aetina production Works under MS driver Does not show image on eDP internal screen right after installing Nvidia modded drivers All external ports ( HDMI, eDP VGA) works with no issues - tested on benchmarks the card itself works great The internal screen could blink several times depending on vBios flashed ( so the card is trying to fire it up) Internal screen is not recognized properly - Using Monitor asset manager i observed that: GTX 860 create two monitor entries 1) Realtime and 1) Registry GTX 970m creates two monitor entries 1)Registry and 2) Registry If I change the max Hz using CRU to 100 and Close/Open laptop screen it will show picture in 1024x768 resolution with no possibility to extend and it also see a "Virtual monitor" attached to real one ( extended)

 

So the main issue is that INTERNAL Display is recognized AS 2 displays 1 connected to the internal laptop port and one into Display port:

vBios tried Premav2, MSI,Dell,Clevo Drivers version tried: 340,350,380,411

 

I searched for a something related to my issue here and found themes which are really near - but with different problems

I have same problem, same panel(dreamcolor) same gpu but different laptop, its hp elitebook 8760w(non-dreamcolor). Have tried n amount of “solutions” but none of them worked, maybe you(or someone) figured this out? I think the problem lies between the eDP to LVDS converter and my display panel because my 8760w is non-dreamcolor

I found the issue. Aetina 970m cards DOES NOT support eDP. You need pure LVDS connection
