What Dell Precision 7710 4k have display module?
Hello, I have Dell Precision 7710 with 4k display module, can someone answer what model and manufacturer of display Dell uses? I ask because I see AUO B173ZAN01.0 (0-4 rev) and Sharp LQ173D1JW33. But I want to know what original display are you using? Thanks.

All of the 4k display panels for the Precision 7710 are advertised as IGZO screens.
LQ173D1JW33 = Sharp IGZO IPS screen
B173ZAN01.0 = From what I've been able to find on the internet AUO has the licence to produce IGZO panels, but everything I have found online claims this panel uses the a-Si transistors in stead of IGZO. The actual product specifications do not state one way of the other, so... Who knows.
My Precision 7710 has DPN: 2RCX9 and it looks nice and sell sold it as an IGZO,
391-BCFL : 17.3" UltraSharp UHD IGZO(3840 x2160) Wide View Anti-Glare LE D-backlit with camera Mic
2RCX9 LCD,17.3UHD,AG,EDP1.3,AUO 1

@JamesJAB1@JamesJAB1 , my Precision 7710 has same DPN: 2RCX9 and it looks good. I just tried understand difference between Sharp and AUO modules. And I think I found it here: Difference between Sharp and AUO Do you also have uneven illumination on a black screen?

Yes, mine has a little light bleed along the bottom right and bottom left. (You don't really notice it unless you turn up the back-light all the way on a dark image.)
My main concern is that our screens where marketed and sold by Dell as IGZO screens, and the only info I've been able to find on the AUO ones claim that they are a-Si
IGZO = Indium gallium zinc oxide (Clear Transistors in the TFT layer for lower power usage and brighter display)
a-Si = Amorphous silicon (Standard LCD screens)
