[Dozer]

hi,

i send a client a working grafik card for 27" 2010 imac
the card is more little that a 27" 2011 grafik card
Chip is ...51

the card is working here tested in 27" 2011

Bios has a red point

serial of the machine from my client is W80431VBDB6

not working. is it possible that i have to flash in the bios with the orange point?

the problem is i dont have the machine here and he want to send only the card back.

The 9051 cards were made with a VBIOS for LVDS screens (2009 21" only) and eDP screens (2010+) If the card has the old LVDS VBIOS then there will be no image on internal LCD, external should work. But as you tested it in a 2011 and the customer machine is a 2010 it should just work. They probably fucked up the LCD connector as usual.
