Hi we ordered 50qty OptiPlex 3050 and 3060's. We are having some major issues with HDMI out. We are not getting a signal. We have updated the video card driver (intel uhd graphics 630), the bios. We ran support assist and everything is up to date.

I tried going to intel and getting the driver directly from there but it wouldn't let me install it. It said to go to computers manufactures website.

I have tested the cables and monitors on working machines and there is no issue with them.

I have had 7 motherboards replaced ( on new machines less than 1 month old). about half of them the hdmi would work.

We are hooking up to brand new ViewSonic VA2252SM.

I did go into the bios and change the display from auto to intel. That seemed to fix one machine but not the rest.

I installed the driver from the viewsonic website also.

Any ideas?

thanks
