Hello,

Recetly we bought acer triton 500 with TB3 port.
RTX 2060 + 8750H 144Hz + G-Sync monitor Predator XB1

We have a couple of problems.
Recently I've read that the windows is working on the fix which will include the ability to properly switch the GPU on the Nvidia or AMD (dedicated one) when the integrated graphic card is apparent.

So I've hooked up the adapter or docking station and this happened.

I´ve set my main monitor to the DisplayLink one.
I opened app (rocket league, Pubg, Adobe premier or some demanding app which will run or hook onto the NVIDIA one)
In every case, if it was a game it was starting but the picture never showed up.
I get the white screen or blank screen and nothing was happening but in the device manager, I can see it is running and I could even hear the sound.
On the adobe side it was clearly running under the iGPU one the performance was horrible. Even tho i set it to run under Nvidia one.

When I set the game or app to run on iGPU it started normally but it was hooked onto the iGPU instead of the Nvidia one.

As I've read the forum i saw that there should be a fix for that in recent windows updates.
But suddenly i have the newest (windows insider) and still, it is not working.

Also there is a problem with G-sync monitor but i have seen on your forum that the G-sync monitors can be out of spec...
Will there be any fix regarding this?

If you want to i can provide you with everything that you need.

Also tested another thing when I tried to run the game and set my main monitor onto the built-in one then it was running and I could even move it onto the DisplayLink one but the game and GPUs behave strangely. The FPS counter showed slightly lower fps and the device manager showed that the iGPU is more utilized than before which should be correct.
But on the screen, it was apparent that the FPS that it is showing up are not correct and are same as you run the app under the iGPU setting.
When you drag the app back onto the built-in one the FPS and utilization jump back to where it was.

I hope that you can provide me with some good info or some info about incoming fix regarding this and Nvidia Optimus and so on.

The chip inside the USB 3.0 adapter is DL-6950.
