I have a Z590 with i7-11700K and a Geforce GTX 1080 GPU with dual monitors. I am currently unable to boot to bios with both monitors connected - I have to disconnect the monitor connected to Display Port. Is there a fix for this or does this MB have an issue with older GPU's? Thanks for any help.

Your situation sounds similar to a problem for which NVidia made a firmware update (the common symptom is not seeing output on DisplayPort monitor until after Windows driver is loaded). I am not a graphics card user myself, but one place to look for such firmware update is at this URL https://www.nvidia.com/en-us/drivers/nv-uefi-update-x64/

The only other idea I would have is checking a setting in the BIOS Settings\Advanced\Integrated Graphics Configuration, I think you need to press Enter to get the sub-menu, then look at the setting IGD Multi-Monitor and see whether changing it from the current setting to the other one improves your situation.

Thank you. Yes I already tried the firmware update. Nvidia's update did not work for my GPU and MSI had no firmware update for this card. I'm wondering if I need to just upgrade to a more recent GPU and if so what cards are compatible.

Let's take a step back. What do you mean unable to boot to BIOS? Do you mean unable to get the BIOS settings screen to display on any monitor? But still able to boot into Windows? Or is there some type of "hang"? I'm sorry but something seems unclear. Presumably you are saying that with either type of single monitor you can both get to BIOS settings screen and get to Windows. Then there are variations, such as whether you always have both monitors connected to the GTX 1080, or whether you might have either of the monitors connected to the motherboard's graphics.

It is "normal" that BIOS screens would only be seen on one of the monitors when both are connected. With two monitors, such display would probably be to DisplayPort. If your DisplayPort has some compatibility issue such as the ones needing various NVidia firmware updates (assuming connections to GTX 1080) or with whatever resolution BIOS is trying to display, then such problem would presumably occur regardless of whether you have both monitors connected or just the DisplayPort connected. You'd only see BIOS on HDMI if it was the only monitor connected.

P.S. The following is from MSI card's FAQ, in case your situation is experience with multiple monitors order of priority on this card in older non-UEFI PC vs this card in newer UEFI PC:
Q: I have 2 monitors, one is with HDMI connected and the other is with DVI. I've noticed whenever I enable Windows 8/10 WHQL Feature in motherboard BIOS, my post display changes from DVI to HDMI monitor.
A: When "Windows 8/10 WHQL Feature" is enabled, the VBIOS will change to UEFI GOP VBIOS Mode, the post display sequence then will be changed to DP>HDMI>DVI.

Sorry. I'll try to be clear. I'm not talking about onboard MB graphics at all. When I start or restart the PC with both monitors connected to the 1080 I get nothing on screen until the windows desktop, no MB logo, nothing on either monitor but I can eventually boot to windows If I try to boot to the bios by pushing the "Del" key the PC will just hang and I will need to power off. As a matter of fact it will hang if I push any key during boot up. But If I disconnect the monitor connected to Display Port I get a boot logo onscreen and I can boot to the bios. So currently I must disconnect one monitor to boot to bios, reconnect the monitor and restart to boot into Windows. Not sure if this is relevant but one of my monitors is older and only has DVI ports so I use a DVI to HDMI cable. This is the monitor that always remains connected. Thanks for your help.

I still think I need to paraphrase some for troubleshooting. Your desired monitors, from GTX 1080 are DisplayPort and HDMI (board) to DVI (monitor). Is there a reason you are using that HDMI connector instead of DVI (from board) to DVI (monitor) which should be more straightforward? The rest of your symptoms remain sounding to me like those NVidia DisplayPort firmware issues supposedly solved by update (that is, not ever seeing BIOS screens on DisplayPort - only seeing them on non-DisplayPort when DisplayPort is disconnected). You first say that both monitors connected end up at Windows desktop, no display before that (my thinking is that it "should" be displaying to DisplayPort so no reason to look for it on the other monitor). If you are trying to get to BIOS with some key like Del then it is still going to try to display on DisplayPort, so it might seem like hang to you. Some other keys would act similar, such as F11 which would be prompting you to select boot device. If I've paraphrased correctly, the part that remains confusing to me is when talk about needing to disconnect DisplayPort monitor then reconnect it and restart to Windows, which seems to contradict what you said about getting to Windows desktop (but not BIOS) with both monitors connected. Are you perhaps describing some difference between "power on" and "restart" style boots?

If my paraphrasing is describing the issue, it might make sense to move this topic to whatever section of the forum covers MSI graphics cards, hoping that someone there might be more familiar and know whether there is indeed some firmware update appropriate. Still need to mention details such as the motherboard since it is presumably related to UEFI.

Note: you might want to name your DVI monitor model in case it has some issue with available resolutions that BIOS might be trying to use, but my guess at this time is that is not part of the problem you are describing (since you can see fine with just that single monitor).

MSI Nvidia GeForce GTX 1080
Which model exactly? There are many 1080 GTX MSI models.
Is it this one from your signature? => MSI GTX 1080 Gaming 8G ?
What vbios version GPU has installed?
Have you tried using a different GPU if so, does this issue persist?

Yes, MSI GTX 1080 Gaming 8G. Not sure, is this vbios: 86.04.17.00.8B. I believe this is a Display Port 1.4 issue which the firmware update was designed to fix. I found a setting on monitor in Display Port that lets me select DP version. Was set to 1.4, I changed to 1.2 and now it works normally. I don't know the difference between v1.2 and 1.4 but I would like to be able to use the best and most current settings.

You have latest vbios installed. If you still have issue, then check for monitor FW update.
Or it could be some compatibility issue between your monitors and the GPU used or at least some of the display's cables.

Regarding NVidia's firmware update tool to avoid blank screen on DisplayPort 1.3&1.4 monitors, supposedly: 'Nvidia's tool doesn't update your graphics card's video BIOS, so you won't see a change in tools like GPU-Z after applying it. Instead, it checks the firmware for the UEFI GOP (graphics output protocol).'

Thank you guys very much for your help. Not sure what to do at this point but at least I don't have to disconnect the monitor anymore to get to bios.
