Hi,

I own the S2415H monitor, and the HDMI input is not working. The VGA input is working, but once I try to connect with HDMI cable, the S2415H just does not recognize any signal.

I tried to connect with different cables (that work on the same computer with other screens), and the solution in here. Additionally, I installed the drivers from the website, but the Dell Display Manager program can't run (even though it was installed successfully and recognized the monitor through the VGA cable).

When I try to open DDM I get this error:

Thank you!
