When three DVI monitors are connected to a UD7 thin client over passive DisplayPort adapters, only one or two monitors are detected.
This solution is only persistent if energy saving is switched off.
- Open the thin client's Setup.
- Go to System > Registry > x > xserver0 > force_reconfig (Registry key:
x.xserver0.force_reconfig) and set the value to never.
- Click Ok to save the setting and close the Setup.
- Restart the device.
All three monitors should be detected.
