Hello there! How's going?
This graphic card has 1 hdmi port and 3 DP. This pc needs to have 3 monitors connected and a projector to the graphic card. Gpu's HDMI works fine(regardless of screen) but the other 3 that use the DP don't. The screens have these connections:
-projector HDMI to the gpu's HDMI.
-1 screen has a DP connected to one of the gpu's DP.
-the others screen are VGA and are connected to the DP with an adapter.
This started happening a few weeks ago when we changed the motherboard and cpu because the original ones were damaged(probably due to a power outage). Before that all monitors were working just fine.
After the install of the new components, I installed the last drivers for this gpu using the adrenalin software. I also updated windows but neither helped.
All screen are working not only because they emit a "no signal" message but because I tried them with a HDMI adapter and they worked fine.
So I don't know what can I do. If you need more details or a more detailed explanation, let me know. English is not my first language so sorry for any mistakes.
I appreciate any help. Thanks!
