I cannot confirm, but this would be what I suspect might work.

(1) Flash back to the STOCK BIOS
(2) Run the display port firmware update (as you did)
(3) Re-flash the modified BIOS back to the card.

I would ignore what the tool says as long as it works. If that doesn't work (blank display) then the only options are to use iGPU or HDMI for the boot screen and when you get into windows use the display port.


The Gigabyte BIOS' are posted in the OP, you just need to know which revision (F3/F4 or F10)

I've tried all DisplayPorts, and they exhibited the same issue of no post screen. Just to be clear, I had the "blank screens on boot until the OS loads" issue.

If I have any new findings I'll post an update in this thread.

As for the DP BIOS and Chrome issue, all is fixed. DP BIOS is now applied, so now I have both BIOSes modded. Games run well too. I was worried that I didn't mix up the BIOS flash but all is well.

Chrome issue was related to GPU Shader cache. Deleted it and now it works with HW acceleration.

I may have had to revert to the STOCK BIOS to run the tool also.. I don't remember it was so long ago. Variances could be which display is being used at the time of the update or possibly if the MUMOD BIOS was newer than your original BIOS. For example they shipped with the F3 BIOS, and have since released an F4 BIOS (if yours isn't based on F10). If you ran the tool and it worked with the F3 BIOS but the modified BIOS is now the F4 BIOS, maybe that throws something off. So you MIGHT have to flash the STOCK F4 BIOS, update the display port firmware with the F4 STOCK BIOS and THEN flash the modified F4 BIOS. It might be worth a try.

"Without the update, systems that are connected to a DisplayPort 1.3 / 1.4 monitor could experience blank screens on boot until the OS loads, or could experience a hang on boot.
The NVIDIA Firmware Updater will detect whether the firmware update is needed, and if needed, will give the user the option to update it.
If you are currently experiencing a blank screen or hang on boot with a DP 1.3 or 1.4 monitor, please try one of the following workarounds in order to run the tool:

Boot using DVI or HDMI
Boot using a different monitor
Change boot mode from UEFI to Legacy; or Legacy to UEFI.
Boot using an alternate graphics source (secondary or integrated graphics card)

Frosted racquet Hopefully a final update. The nVidia tool for updating DisplayPort firmware seems to try and reapply/re-flash the BIOS as well when updating the DisplayPort FW and likely fails because the BIOS is unsigned.
I've switched to HDMI, since it's the easiest solution for no video @ post.

Thanks again for replying.

Also, turning off hardware acceleration in Chrome is a workaround for my YouTube issues. Haven't figured out why exactly it's a problem now all of a sudden.

May want to double check the DD and DP again to make sure.

The BIOS' are just copies of the stock BIOS' and I didn't modify anything other than power, voltage and CLK values for the most part. AFAIK the DP firmware was not included otherwise this seperate download would not be required (my 980Ti's are gone now so I cannot check this).

Does it play games and run benchmarks ok? Just Chrome? If not ONLY Chrome I might try DDU first and then reload the latest drivers.

If ONLY with Chrome, zap it and do a fresh install.

Also, make yourself a bootable Win10 (free and easy to make) so you can boot into a fresh O/S, load the drivers and see what happens.

Ah, I see the problem. Since I'm only using DisplayPort, there's no guaranteed way to switch to a DD BIOS (the only one I modified before) since the DD BIOS DisplayPort is actually a "Schrodinger cat" situation since it can be both a DD and DP switch. Currently, I'm being forced to boot a DP BIOS regardless of which DisplayPort I plug the monitor in. I will flash the MUMOD DP BIOS and see how it goes.
If you use the display ports all the way on the end (the ones not active in the DD BIOS) it should force the DP BIOS so you know for sure it is running DP and not the DD slot with a DP BIOS. I do think that a single display port would most likely use a DP BIOS but it might depend on which of the 3 ports are used. I want to mention that sometimes the GPU may force you to use a different display port if they are not all populated. You can test yourself, if you get no video unplug and try a different port one by one in those situations should no video occur, same symptom but different reason. It's not clearly documented which combinations require you to use which ports since there are 3 of them you just have to experiment. I always had 3 display ports and HDMI populated at the same time so I didn't have any unused.

The biggest thing is to ensure that you are not using the DD slot with a DP BIOS. The only way to make sure which one is loaded is to use the ports that are exclusive to force it to load. Also I wonder if you need to run the update on EACH display port.. I wouldn't think so but maybe..

For anyone following along, DP BIOS does not stand for display port. It is just a coincidence so I tried not to refer to display port as DP but I had to edit a few places lol..
