DP to hdmi splitter vendor small print:  The total bandwidth of 21.6Gbps (100%), when connected to a DisplayPort 1.2 port, is shared among all attached monitors. Make sure the total combined resolution bandwidth between all displays does NOT exceed 100% || 3840x2160 [NAME] (40%) || 2560x1600 [NAME] (38%) || 2560x1440 [NAME] (35%) || 1920x1200 [NAME] (30%) || 1920x1080 [NAME] (22%) not sure if I understand the above correctly, but it seems to say it does not support three 3820x2160 @ 30 hz as that would take up 120% bandwidth, meaning it cannot support three 4k monitors.  two 4k is doable. The ASUS gt730 w 4xhdmi appears to be single slot width, as this pic shows it can be stacked.  If that is correct, can you try install in the lowest PCIe x4 slot? [IMAGE]   [IMAGE]    
I have in my XPS 8940: 11th Gen Intel(R) Core(TM) i7-11700 @ 2.50GHz, 2501 Mhz, 8 Core(s), 16 Logical Processor(s) Also: Adapter Description Intel(R) UHD Graphics 750 There are only two video ports on this system, HDMI and one Display Port. I DO NOT have a graphics card installed. So I looked around and found this: [IMAGE]ASUS NVIDIA GEFORCE GT 730 See: [URL] Can someone advise that since this graphics card that has a PCIe 1 connector on it, will work on my XPS 8940 PCEi x1 port?  I'm also considering going with a Display Port to 3-port HDMI like this one: DP to 3-port HDMI  and I wondered if this would be a better solution? 
XPS 8940, need 4 HDMI ports
