7590 + WD19TB + CRG9
I've seen some talk about the Samsung CRG9 on here. Does anyone know if I could get it to work at it's full 5120x1440 @ 120Hz resolution and refresh rate? My 7590 has the intel UHD 630 integrated graphics adapter and nothing else.
Down the road I might get a external HD. But I would like to be able to use the CRG9 w/my 7590 and my WD19TB in the mean time.
Thanks in advance.

@nsl22 As explained in the manual of the Samsung CRG9, 5120x1440 at 120 Hz requires DisplayPort 1.4. The WD19TB supports that, but only when used with a system that also supports it, and your XPS 15 7590 doesn't. The XPS 15 7590 has all display outputs wired to the Intel GPU; the NVIDIA GPU if your system configuration includes one operates as a render-only device when needed, using a technology called NVIDIA Optimus, and does not have direct control of the display outputs. The Intel GPU in that system only supports DisplayPort 1.2, and therefore cannot run 5120x1440 at 120 Hz. You can run that resolution at 60 Hz though.

Thanks.This answers my question.
To add to this, according to the manufacturer's website, their external GPU box (egpu) will allow me to run the CRG9 monitor. https://www.sonnettech.com/product/egfx-breakaway-box/techspecs.html#techspecs
It doesn't say at what refresh rate though. I'm guessing it depends on the GPU that you put in the box.

@nsl22 Happy to help. As for the eGPU, yes it absolutely and entirely depends on what GPU you install. The eGPU enclosure is basically just a PCI Express slot in a box, and then Thunderbolt 3 is basically just an external cable to connect that eGPU PCIe slot to the system's motherboard -- so the eGPU enclosure wouldn't affect available resolutions, refresh rates, total number of displays, etc. It's entirely GPU dependent.
