Sorry for the extreme post here, have a TLDR if you don't have the time.
Ok, this one has me really perplexed. I have built around 6 PCs before, and never really had any problems. Today I upgraded my motherboard, video card, RAM, and CPU.
The parts are as follows:
Asus Maximus Hero IX
Asus ROG GTX 1080ti OC
Intel i7 7700k
G.SKILL Trident DDR4 4133mhz
Dell 2715q 4k Monitor (had this awhile, it has always worked fine.)
Now, I have 3 monitors, when I booted up, I wanted to simplify it, so I had my main monitor plugged in all by itself VIA the first DisplayPort. The system booted, but no bios or any video on the monitor. Commence the freak out.
After about 10 minutes of checking for error codes and whatnot, I decided to plug in all of my monitors and see if the BIOS was showing up on any of them. Sure enough it did. It showed up on my cheapest and smallest monitor that I have plugged in through a DisplayPort to VGA adapter. So, knowing that that particular DisplayPort on my 1080ti must be working, I unplugged all my monitors and plugged my main monitor back into that DisplayPort. Again, no video/BIOS. I start googling, and I find some posts saying that after Windows is installed, the BIOS will then choose your main monitor through whatever you have as your default Windows monitor. So I set up the BIOS and install Windows using my crappy tiny monitor.
Once Windows was installed, I go download the newest 1080ti drivers and installed them. Restarted, and went to look at the multiple display settings. Only one monitor detected, the small one I've been using. I plug my 3rd "monitor" in, which is a Vizio 4k 50" TV VIA an HDMI port, and it is immediately detected, and works. So my main Dell 4k monitor has 3 inputs. DisplayPort, MiniDisplayPort, and HDMI. I try the Mini DisplayPort thinking maybe the the regular DP cable got messed up when I was plugging it in or something. No display. Finally I try the HDMI cable, and it works. I have a display on my main monitor. YES, I am choosing the correct input on my monitor when trying the different cables.
This however is not a good solution, I would much rather have my monitor go through my DisplayPort as my HDMI connection is locked at 30hz.
BIOS is up to date. All relevant drivers are up to date.
To really simplify this...Forget I have 3 monitors. Pretend I have one, the Dell 4k. It only works with HDMI and neither of the DP/MDP ports. This is in Windows and the BIOS. Yes, the correct input is selected on my Dell 4k.
I am tearing my hair out here, any ideas??
Drivers are up to date. The DisplayPorts are not working on my main monitor. Main monitor is only working with HDMI. BIOS won't show up on my main monitor unless I have it plugged in VIA HDMI and it is the only monitor plugged in. My HDMI is only 30hz, so I really need to get the DisplayPorts working. My cheapest and worst monitor works fine with a DisplayPort on the 1080ti to VGA adapter. Yes I am choosing the correct input on my main monitor, I have tried all 3 DP/MDP/HDMI and only HDMI works. I have tried both of the DPs on the 1080ti, they both work with the cheap VGA adapter/monitor, but not neither work with my main Dell 4k Monitor. This monitor worked fine with the same DP cable on my GTX 980
