Post 4 - if your GPU has two display ports try the other one and if that does not work, if possible try HDMI
I think your monitor has DP and HDMI
I do not know what has caused it - but sometimes HDMI will display BIOS screen and DP will not
Well.... it's a long story.
Vid card has 1 HDMI port which I need to use for the TV, cause it only has HDMI.
Vid card has three DP ports, BUT.... there's only one of those I can use for the monitor.
Are you ready for this?
If I use either of the DP ports marked with the blue dot... The BIOS splash screen comes up on the TV only, and the Windows Welcome screen comes up on the monitor only.
If I use the DP port marked with the green dot, then both the BIOS splash screen and the Welcome screen, come up on the monitor.
If this stuff wasn't happening to me, I would think it was a fantasy tale.
My previous vid card, the 780 Ti, had a DVI port and an HDMI port. On that card there was no problem.
HDMI to the TV and DVI to the monitor. I've even tried to fool the vid card by using a DP to DVI adapter.
The vid card wasn't fooled.
Everything worked fine though, with HDMI to the TV and the green DP to the monitor, until Saturday November 13th.

I thought it may be something to do wth the DP
I did not of course know that you had two displays
I did not see this mentioned in either thread - but if I missed it I apologise.
May I presume you did NOT know about the difference in which port you use, until I mentioned it.
I am a little confused if the card has 3 DP ports -
and one HDMI and that HDMI is to the TV
why please can there be ONLY one DP you can use for the Dell Monitor.
and does this
mean as of NOW or should I read it asIf I use the DP port marked with the green dot, then both the BIOS splash screen and the Welcome screen, come up on the monitor.
Prior to November 13th.
=====================
I am not surprised by this
as the BIOS of the GPU controls which port/s are active at boot.If I use either of the DP ports marked with the blue dot... The BIOS splash screen comes up on the TV only, and the Windows Welcome screen comes up on the monitor only.
by that I mean before the windows boot manager loads the drivers for the card
===================
I still do not know what has caused the change
Would it be silly to ask if CSM is configured in firmware - rather than UEFI
BIOS is set to UEFI. I've tried with CSM enabled and disabled. Same for AMD fTPM.
I even tried with the ASUS boot logo turned on and off. I've also tried with Post Delay Time set from 2 sec. to 10 sec.
During boot, where I should be seeing a BIOS splash screen, I just see a black screen for approx. 5 sec, which is what I have the Post Delay set to at this time. On a cold boot I DO see the BIOS splash screen. I also see it when I do a restart from within the BIOS.
I don't see it any more, when I do a restart from within Windows. That's what has changed.
And... as I mentioned in post #1, occasionally I get a delay on the Welcome screen after entering the password.
Normally that delay was approx. 1 second. Now it can be anywhere from 1 sec. to 20 sec.
Here's the DELL's connectors...
On Monday, I will call EVGA and see if there's been a BIOS update for the vid card.
I don't think there would be, but ya never know.
I also picked up some CMOS batteries and will probably test with my old 780 Ti, over the weekend.
I could not find one.On Monday, I will call EVGA and see if there's been a BIOS update for the vid card.

Good luck with it
I am convinced it is something related to this

I appreciate it is NOT an exact match for your situation but it is VERY similar
When you find it - I will be interested to find what was the actual problem.
Before you started testing Windows 11 on this machine, do you have secure boot enabled in BIOS?
I remember from my old machine, it skips the splash screen when secure boot is enabled but it wasn't a big deal to me back then because the computer runs normal.
Also, check under "Boot" tab if the "Full Screen Logo" is enabled or in Auto. Try to disable and see if it affects the splash screen.
It's FIXED !!!
Now I'm not 100% sure HOW I fixed it, but it's one of three things.
1. Which order I disconnect the DP and HDMI cable from back of vid card. (But thinking back, I don't think this is it)
2. IF I have the HDMI cable (to TV) hooked up if I install vid card drivers. (But, I don't think that was it).
3. Is hard to explain, and still doesn't make sense to me. But here goes...
I have an OLD case, and a relatively new vid card. When switching between the Windows 10 SSD and the Windows 11 SSD, I had to take the left side off the case. Now there's no way the left case side could bump the HDMI cable.
Because the case is so old, and the vid card is new... the connectors on the back of the vid card don't line up "exactly" with the slots in the case. Because of the plastic housing on the HDMI connector, I can't push it all the way in to the HDMI vid card connector, which is fine... it's never needed to be all the way in.
Now... the gold outside of the HDMI connector is ground. The metal part of the OLD case is ground, but they don't see to be the "same" ground. (Don't ask me to explain).
So, when I noticed (with LED flashlight), that the gold outside of the HDMI connector was touching the metal case part, I decided... to wiggle the HDMI connector so it was not longer touching. BOOM! The BIOS splash screen is back.
So after testing it about 10 times, I decided that must be it. So I shut down the computer, took the HDMI connector out, and applied a 1/8" wide strip of electrical tape to the gold part of the HDMI connector, right up against the plastic housing.
See the YELLOW line. That's where I put the electrical tape. The size of the YELLOW line is about actual size.
That is where the HDMI connector was touching the metal case part...
Why is the case ground different than the connector ground... who knows.
Why did it just happen on Saturday night, when I have been removing and replacing the left case side for 2.5 months.
I don't know. The left side panel sort of "clicks" into place, when it being re-attached.
I'm guessing that the HDMI connector was NOT touching the case part since... May 2020, until Saturday night.
Short version... with the tiny piece of cellophane tape on the HDMI connector... the BIOS splash screen is back!
/edit
If I could take a pic of it I would. But there's not enough room back there.
Next time I'm cleaning out the dust in the case, I'll get a pic.
/edit 2
Guesses 1 and 2 up above, probably were NOT the cause. I've done both multiple times since May 2020.
I've even had the HDMI connector in and out multiple times.
But I'm thinking I probably never really pushed it all the way in, to the last 1/4 mm, so it's either a funky connector (which I don't believe) or the fact that it was touching the metal of the case, and it shouldn't have been.
@Macboatmaster
That link you posted at the DELL forums? was what I was talking about in post #12... see the pic.
Everyone who tried to help gets a rep cookie. Thanks guys.
OK, here's the back of my case. The RED dots show the two strips where all my vid card connectors are.
The YELLOW dot, shows where the gold metal of the HDMI connector was touching the SILVER (un-removable) part of the case.
And because I am a conscientious computer type person... I just replied to the email from ASUS, who just agreed to RMA the motherboard, that it was not the fault of the motherboard, and everything was working fine again.
