I recently bought a EXP GDC adapter v8.4d for lenovo b590 but it only works if my laptop is 2GB RAM. I can't get it to work on my laptop if it is connected to 8 GB of RAM. When i turn on the laptop with 8GB of RAM with the connected adapter and external graphics card laptop turns on with black screen. In the BIOS it is also not possible to go. I've tried all methods found on this forum, but was not able to solve the problem with the black screen. Please somebody can help me.

Ways to cope with a black screen, which I found on this forum did not help
