Hi, my problem with HDMI output was not as bad as in this picture with one of the last FW versions:

But my monitor (HP 2309m) also delivers with the

no permanent image. A resync takes place every few seconds to minutes. Including slight crisping on the left edge.

But I also wanted to use my HDMI matrix:

By the way, the HDMI/DVI signal only works with a direct connection to the monitor. Using an HDMI matrix (Greathtek 4x2) does not work.

I bought this DVI switch: Aten CS1762A.



What can I say? It works better than expected. Not only can I use the DVI input from the monitor, I can also use the HDMI matrix! I found this device in a small ads. For a fraction of the new price and as unused goods.



I hope this can help someone.
