Not sure anyone is actually interested but just in case it helps somebody... I now have the hub functionality working for both monitors (USB ports working as they should), through the USB C to A cable workaround. Not sure why this has to be the case but at least it works. I am none the wiser why the ASUS PN50 I have does not work with the Dell monitors when connected via USB C, that remains a mystery. Apparently, the PN50 connected fine via USB C with other brand monitors when the retailer had it back for a check. Neither Dell nor ASUS seem to be able or willing to explain the conflict. I really wish I had gone a different direction while setting up my home office but at least I can get on with my life...
Hi all, I hope someone can help me. I'm almost tearing all my hair out over the issue I'm having. I bought an ASUS Mini PC PN50 with AMD Ryzen 7 4700U Radeon graphics which is meant to be capable of a Quad 4K display via DP, USB C x2 and HDMI. I paired it with two U2720Q monitors. But straight away it would not work with the Dell USB-C Gen 2 cable provided with the monitors. This is the message I get: "No USB Type-C signal from your device".  Try as I might it just won't work. I have tried various AMD video drivers, Windows drivers, bought a new USB-C cable from Belkin with no luck. Ensured I am on the latest BIOS firmware, reset my Windows install, no joy. I have connected one U2720Q via DisplayPort but as advised here, I lose all the USB hub functionality which is one of the reasons why I bought this U2720Q in the first place. At some points, during the fiddling, I managed to get the second U2720Q working with the USB-C cable but on restart the problem returns. Now, not getting any joy at all. I have tried an HDMI connection but that too is not working. Is there a problem with the U2720Q and USB-C? Seems various people have had issues but not quite the same as mine. Is it the ASUS PN50's fault? I think not, as other reports of USB-C connectivity issues abound. Anyone have a similar issue? Any solution? Searching for it on Dell's official support pages is a nonstarter as it's the most opaque support I have ever seen. I'm about ready to throw everything through the window due to having spent several hours on this problem and have had absolutely zero help from the retailer. Thanks in advance.
U2720Q, does not work via USB-C on ASUS PN50
