Hello, just got used 980 card, model is 04g-p4-2983-kr
Which version of a bios is latest for this card and where i can download it?
 
Factory Installed ver is 84.04.31.00.82, but with this ver, pc mon, hooked with DP, stays black after resuming from sleep.

The vbios on video cards rarely need to be updated. The solution to your problem would be to disable sleep and just turn off your monitor when away. If you still want to try and update your video card with a newer vbios you can try using one located here. 
 
Note: Flashing your video card with an incorrect vbios could cause the card to stop working. Flashing the vbios with a different vbios will void the warranty on your video card. If you ever need to rma the card in the future you will need to put the original vbios back onto the card before rma'ing to obtain warranty service.

Thank you. Disable sleep is not an option, so i`ll try flashing. More over, i bricked my card twice already lol, with bioses i found inside the geforce forum.
Can you ask someone (support, engineers etc) is 84.04.84.00.80 latest?
I already talked with support, for nearly a week, but every time with a new man, result - nothing, but years ago they gave me uefi bios for gf670 momentally.
Warranty already voided lol, sticker with sn come off from heat and got lost.
