Hello Walter, the behavior you are experiencing could be a compatibility problem between the Board and the USB3.0 of your monitor. I suggest you to install the latest USB3.0 driver available for your motherboard and test a different device on it just to verify if it is working as expected. Intel® Download Center
You may test a regular 3.0 flash drive, and check if it is running at that speed.
Regarding the issue with the start screen, I would recommend you to do a clear CMOS on your board.
- You can also test another monitor
- Check the TV or monitor source is HDMI, VGA or DVI, depends on the video card you are using.
- You can try doing a BIOS update. If the current BIOS version is the latest one available, you can try to reinstall it. Intel® Download Center
I'm already using this latest USB 3.0 driver and my USB 3.0 flash drive runs with about 150 MByte/sec - the expected speed;
how can this compatibilty problem between the Board and the USB 3.0 of the monitor be solved?
my video card is a nVIDIA Quadro FX 380
the monitor I had before (a 24" HP with 1920x1200) showed the start screen;
how can this be influenced whether this is shown or not?
is the CMOS cleared by the jumper on the board that is put the other way for a short time?
Walter, we tried to make as many third party components compatible as possible, but do to the sheer quantity of these third party components we cannot always guarantee compatibility. I suggest you checking if you are maybe missing the USB 3.0 drivers from the tv.
Regarding the CMOS, please follow these instructions. How do I clear the CMOS?
