3.8 Known problems/issues

• USB 2.0 transfer is limited to 150 Mbit/s with SDL4.
• A display is always emulated by the SDL4 transmitter using EDID data and hot plug detection, so DVI-
compatible operation is possible. For this reason, faulty representations may occur during operation with
multiple displays. In Windows, a connected panel is reported by the video driver even in the following
situations:
° No cable connected
° No connection established yet between the SDL4 link module and SDL4 transmitter
These faulty representations can be avoided by appropriate configuration in BIOS or via the graphics driver.
• If problems occur with the ETH1 or ETH2 interface (connection abort, slow data transfer, etc.), the Ener-
gy-Efficient Ethernet feature can be disabled in the driver as a possible solution.
