HPFOCUS

Hi all, I'm new on this forum and excuse me if I write this post in english but I'm italian and I don't know the chinese.
I have an HP 8570w and recently I have bought an NVIDIA Quadro K2100M (N15P-Q3-A1).
I have installed that graphics card into my HP 8570w (with not DC display) but the display doesn't work, it remains black.
I have reinstalled the original video card K1000M and all work correctly, so I don't know if the new graphic card K2100M is broken or if I have to do something to get it working (for example update or modify bios configuration).
I read in some topics that the K2100M works with HP8570w but I don't know if it's necessary to flash the vbios of K2100M with a compatible vbios for HP 8570w (with not DC display).
I have the latest Bios (version 68IAV F.43 10/08/2013), what I have to do?
Kind regards.

Point is your k2100m vbios must support lvds signal output for generic screen panel. DC screen is using edp signal.

if your hardware parts are ok, try to upgrade vbios from bebow link.

Is the vbios that you have linked (in the K2100m.rar) the version that supports lvds signal output for generic screen panel?
I don't know how to flash the vbios because I have only a black screen.. can you tell me anyone who sells the k2100m already flashed with a compatible vbios for 8570w with generic screen panel?
Thanks a lot for support.. :)

hello，this link can fix your problem。use Google Translation。

display black you can try vga port

If the google translation is correct, I have to flash the k2100m with the vbios 80.06.61.00.08 (file 1.ROM of the attachment, without overclock), is it right?

msi vbios or start up with vga port，switching with Fn+F4

Ah ok, the msi vbios is the version 80.06.69.00.06, so the right vbios (without overclock) is the file 1.ROM in the subfolder 微星80_06_69_00_06.vbios of the attachment. I really hope that it will work..
Thanks very much at all

After vbios flashing it works!
Thanks very much at all!

What is the difference between the video bios versions in regards to the HP 8570w? Is a specific version required?
I'w come across three different version so far:

#1: 80.06.68.00.03 is the only verified version on TechPowerUp.com, though others are available but these are not recommended.
#2: 80.06.61.00.08 was used in a video tutorial.
#3: 80.06.69.00.06 was used in two forum posts with good results.

Does it not matter which one I choose or would for example #1 not work since it seems "official"(might be wrong on this though)? I would assume both #2 and #3 to work but would they result in different performance or is it all the same?

Thanks :)
