DIsplay Mirroring using Dell Rugged Tablet 7202 and Auxillary Display Link

I must say (being old enough 2 be a Pappy) this should be copied and pasted to NVidia’s R&D team…the fact that even granny’s (& pappy’s) know…they got issues :grin: :rofl: :joy: :wink: says it ALLLLLLLLLLLLLL :weary: come on Nvidia…get with the GAME!!

Just connected the HP directly to the 24" Dell monitor using an HDMI to HDMI cable and VIOLA, I am mirroring the screen. The Dell 7202 has a mini HDMI port that will likely provide the same results going directly to the 24" Dell monitor. My issue is that i will still be unable to access the DisplayLink port to run other accessories. I’ll contact Dell and see if they have a mini HDMI to the DisplayLink cable, not sure what that end is?

Thank you. I’ll see what the Dell website has on a cable

Is the Ubuntu 20.4 release similar to the Mint 20.4 release? If so, will the instructions in the below link be helpful to me?

Thank you,

Updated the Dell Ubuntu Driver and ran update and upgrade commands after reading some sage advice you posted on Jeff.Pro. I see some minor changes although I have no idea how they affect your interpretation of the output. Thank you again for your patience.

It’s pretty hard to compare on the phone, one thing did jump out in the 2nd output was of “Device 3…” USB display… After you had followed that links advice. Could will be it’s not your doing but what you’re fighting against. A good old fashioned bug.

You could probably get a mini-HDMI to HDMI at any local electronics stupid for half the cost of Dell/ +s/h.

Thank you. After some more research it appears that the DisplayLink folks are trying to correct a display bug in Ubuntu, which I assume is present in Mint?

I’ll go ahead and get a mini HDMI to HDMI cable for the interim.

I greatly appreciate your help

Hello,

It’s been a crazy few weeks… Finally received the mini HDMI to HDMI cable and Viola!, I can now mirror to the 24 Dell monitor. The display Link has three USB ports which are all working, including a wireless mouse and keyboard.
It appears that the Display Link folks have a bug and they are working on it with no known scheduled release date. They have a work around for Ubuntu 20.4, but nothing discussed for Mint.
For now I’m back to normal with a few extra wires here and there. I sincerely appreciate all of your help MrDeplorableUSA. You have kept me in the game in this new, to me, Linux environment. Can’t wait to learn more about Linux and convert the rest of my extended family. Again, thank you!
