Question RX 580 causes PC to skip past the BIOS boot screen on startup ?

[username-s]

This really isn't a life-threatening issue or anything, but my PC skips past the post splash screen and straight into Windows. Forcing it to enter BIOS/boot into UEFI mode just shows a blank screen. Similarly, resetting the CMOS also displays nothing.

I recently upgraded from a GTX1050 to an RX580 and thought that it was an issue with the vBIOS (most people seem to have this issue when I was doing research), but the GPU I bought was virtually untouched and even resetting it did nothing.

It boots into BIOS just fine with the GTX1050 driving my monitor, but not with the RX580. I tried again with the RX580 but with a spare small TV (also reset CMOS again) and it showed the splash screen for boot manager/BIOS.

Interestingly, I think it might be a monitor related problem or something to do with both the card and the monitor. I don't know if it's the refresh rate or what but even bringing it down to 60Hz really did nothing.

Not sure how relevant it is, but I'm using an MSI B250 PC MATE motherboard. Here's the specs on my GPU and monitor:

Been troubleshooting for a bit now, would like to get some insight on what I could do!

Was that using the exact same ports and cables?
HDMI shouldn't have any issues with refresh rates or resolutions, it should still display something.

Do you use displayport or HDMI?

did you try getting into the UEFI/BIOS by using windows?

update the BIOS of your motherboard with the old card and try again with your new one

Yes, in fact I tried all ports and cables and nothing seems to work with this monitor in particular. The TV worked just fine

HDMI. I did try booting to BIOS via windows through advanced startup AND cmd. Again, same issue persists where it only wouldn't boot into BIOS or even show the splash screen when I have this monitor plugged in to the computer with the RX 580.

I updated the BIOS right before making this post, also to no avail

The link you provided a subsystem mismatch. I believe this should be the right one:

I tried it before and it yielded the same result:

OK, genuinely think it might be a monitor issue. Tried booting into BIOS using the TV and it worked fine. Switched the input to the monitor while in BIOS and it showed the BIOS just fine. You'd expect that spamming DEL would boot it to BIOS anyway but this didn't work.
