DP/DP/HDMI won't work DP/DP/DP does

[Psittac]

I changed my setup recently, only the main monitor and for some reason now I can't get all 3 to work now. *it's working on all DP no HDMI

 

Main original: 4k oled TV hdmi HDR (Sony A90K 42” Class A90K 4K HDR OLED TV with Google TV | XR42A90K)

Main replacement:  5120x1440 oled dp HDR (Samsung 49" Odyssey G93SC)

Monitor 2: 3440x1440 VA DP/hdmi (35" AOC AGON AG352UCG - Specifications)

Monitor 3: 3440x1440 mini IPS DP HDR (34" UltraGear™ 21:9 Curved HDR Gaming Monitor - 34GN850-B)

I haven't done a lot of testing, but I can get any 2 of the monitors to work though I haven't tried HDMI on the main monitor.  I have tried DP and HDMI on the third monitor to no avail  *edit: I just put it the way my original setup was, second and third to DP main to HDMI and no go

 

**I just hooked them all to DP and it works....  I don't want to use my last DP slot because my VR headset uses DP.  I'm going to retitle.
