Programs FAIL when using external monitor

Beansalk

This issue is pretty frustrating. I've gone through Acer customer support, Nvidia, Microsoft (windows), and Adobe and nobody has been able to help me for what is clearly a graphics card issue on my Aspire R5. I assume its a driver issue but I bought this laptop from Acer for the sole purpose of editing and now I have to severely restrict my workflow by being limited to one screen.

This issue has gone through several stages. When I first bought it worked but occasionally had some glitches, shown here: https://www.youtube.com/watch?v=6KlJvzcQ0jg

Now it doesn't even do that. As soon as I plug in the HDMI my program just goes white. https://www.youtube.com/watch?v=cGTJR7-E_Ys

I even sent the laptop in to Acer support and all they did was reset it and send it back... after I told them I already did that.
I've updated the drivers straight from NVIDIA's website and from Geforce Experience. When I talked to NVIDIA support hey straight up told me to just buy a different laptop.

Any advice would be very welcomed
