So if it only works in Windows, this is a sign of the routing of the Displayport lanes from some component. Probably in the display. You can only buy another one!
I don't know the display(NE173QHM-NY7) but AUO would be better!

That is a really nice display upgrade!

 

Not sure if there is reason to believe that the display is defective but in case it isn't have you checked if you can see the bios via an external monitor?

After all you can potentially get a display output with HDMI, mini DP and USB-C/TB3.

 

If one of those options was working that would be good enough for me and I would keep the display as it has QHD resolution and it is superior to the old QHD option that only was a TN panel with a lower color fidelity.

Solved by replacing vbios 😁

Logo appears 😁 at last replace vbios solve the issue

Great news and to my knowledge the first time that somebody has this display running in a P775 or P870 on this forum.

 

You mention Freesync, do you have an AMD GPU running or was that a typo and you meant GSync?

 

In any case it would be great to know for others which cable you used and which GPU and of course the vbios.

Do you know if there are similar brackets for 15.6" laptop panels?

 

Are you able to use freesync?

Can this display fully function with any RTX 3-series cards? And if the problem of the lack of boot logo is related to the bios of the video card, then what should I do in this case? 

[Maro97]

hello ..... i dont know if this lcd fully function with rtx 30xx i use it only with gtx 1070 and the boot logo fixed by flashing other gpu vbios

@Maro97 Hello, anyway thanks for sharing the solution to the problem with your GTX1070 hardware configuration, at least a lot of things have become clearer now.
