De splitter, is die passief of aktief?
Even een beetje rondgegoogled voor je, schijnt een driver probleem te zijn om digitaal dvi naar hdmi te versturen naar beeldschermen.
Standaard windowsdrivers werken maar alle drivers vanaf WHQL 160.0 weigeren dienst.
Iemand heeft een oplossing gevonden:
I've discovered a workaround for this problem. Basically you can use a registry key to override the monitor advertising itself as an HDTV (by setting the number of EDID extensions to 0). Using the following steps, I am now getting proper 1920x1200 resolution on my LG monitor:
1. Start the installation of the latest Nvidia drivers and cancel out once the files are extracted
2. Open nv_disp.inf. By default for the current drivers this is in CNVIDIA\WinVista\169.25
3. In the [nv_SoftwareDeviceSettings] section add the following:
CODE
HKR,, OverrideEdidFlags0, %REG_BINARY%, 1E,6D,3F,56,00,00,FF,FF,04,00,00,00,7E,01,00
NOTE
The first 4 bytes (1E,6D,3E,56) in my OverrideEdidFlags0 are specific to the LG monitor I'm using. For other monitors, you will need to replace them. Using Phoenix EDID Designer (Google it), extract the current EDID and open up the byte viewer. The bytes are in byte 8 through 11.
4. Uninstall your current drivers and reboot
5. Install the modified drivers by running the previously extracted setup.exe. By default for the current drivers this is in CNVIDIA\WinVista\169.25. You'll get a warning about the driver not being signed because of the modified inf. Just press OK.
