Photoshop cc 2019 not detecting a GPU

I got the same problem, but I accidentally found the solution. I tried to open photoshop today with my laptop charged and it recognize my nvidia GPU. and when I unplug the charger and re-open photoshop, it cames back to integrated intel HD GPU.

by the way, I changed the default graphics processor to nvidia in the nvidia control panel. I hope this helps

I have an Asus G notebook with two graphic cards too. Drivers were up to date, and photoshop CC too.

I had the same problems too, but I finally made it work.
Here is what I've done : disable using a GPU in Photoshop performances, disable the integrated graphic card in windows. After that, i just ran Photoshop and enabled my nvidia GPU. I closed Photoshop, reactivated my integrated GPU, and ran Photoshop => it worked, it still uses the nvidia card atm.
I hope it can help?

Hi there,

Multiple graphics cards with conflicting drivers can cause problems with GPU-accelerated or enabled features in Photoshop. For best results, connect two (or more) monitors into one graphics card.

If you must use more than one graphics card, remove or disable the less powerful cards. For example, assume that you have two different cards using two different drivers—an NVIDIA graphics card and an AMD graphics card. In this case, ensure that Photoshop has been assigned the High Performance graphics card rather than Integrated Graphics or Power Saving graphics card.

Hi

The only thing I have seen work on this is to :

First make sure the drivers are up to date on both GPUs (Intel and Nvidia) using drivers direct from the manufacturers not Windows update. In the case of NVidia choose Advanced and then Clean Install during the installation process which will remove remnants of old drivers. I don't know if the Intel driver installation offers the same.

Then follow step 7 here :

I wish I had a solution for you. I used to have a dual card like yours. I will never buy that setup again, due to issues like what you're having. I would avoid Intel at all cost, and also an integrated card.
