TIPP: Troubleshooting with external Graphic Cards on Notebooks | NVIDIA

[markusq70451472]

As I came just today about this issue I would like to provide a little solution which might help others like me who will have a External Graphic Card.
As it is my first time installing and using an external Graphic Card with a Notebook I feld a bit "stupid" running into this. But hey we are all Humans. And if Someone else will bumb into this issue: Here a solution which might help 🙂  

Situation is: 

Laptop has internal NVIDA Graphic Card (mine is Quatro T1000)

And added was a  external NVIDIA GeForce RTX 3080

Connected it was immediatly autodetected by PhS and AI & working! - while it wasnt with PPro & AE.

FIRST ISSUE:

Note that NVIDA will tell you your driver is up to date. Well they are wrong if you have two NVIDIA Cards. 
So you want to select the Driver for the external Card, download and install. 

As a result, PPro and AE will do their job from now one  but not PHS and AI

Suddenly the external Card was not regonized. 

SECOND ISSUE

Some Q&A will tell you to Unintall OpenCL or things like: Open the Control pannel / Systemsettings of NVIDA and go to "3D-Settings => Program settings => select PHS => Choose "NVIDIA High performace processor" 

This won't solve it!

Solution: 

Go to "Confuigure PhysX " and select the external Graphic Card in the DropDown and check the "Reserve for PhysX"

Working. 

Hope this will help anyone. All the best

Hi @markusq70451472 this is covered on this page as well. In most cases users have an NVIDIA card AND an integrated Intel GPU causing conflicts in PS.

@Kevin Stohlmeyer  well, yes - and no.  With the external GPU you have in total 3 Graphic cards.

What is shown in the mentioned link only tackels what I described in the upper part. 
This won't help as the system still uses the Notebook Internal Card. I
was there, it didn't help until i was changing the PhysX Settings. And thats the part which is not explained in the mentioned article.

Which are helpful if you have two cards.  @Kevin Stohlmeyer  plase read what i wrote at "Second issue" 

Additionally i want to highlight my screenshot and translate it into English: 

It says "UNKNOW GPU" So it didnt say incompatibel . it really says "I don't know who you are"  - which is a totally different story compared to all the solutions given.  And the only solution was to explicid change the PhysX Settings - which is NOT tackeld in any of these Articles (if i am not blind)  to the one of the External GPU.  

AND YES: You Could deactivate the Internal NVIDA - But you won't if you take the Laptop with you and leave the External GPU at the desk.

Hi @markusq70451472 I don't appreciate your tone "translating into English" "if I am not blind". I understood perfectly well but your answer is not the only correct option. I'll leave this conversation now and wish you well. Not getting into an I'm smarter trolling arguement the day before a holiday.

It was not ment to be rude or trolling. So apologies for seeming so.  Have a nice day 🙂
