Hi,
I have i-tec USB Display Adapter TRIO (http://www.i-tec-europe.eu/?t=3&v=130), (DL-165 Adapter), and I am using Windows 7 64bit on Acer 6920G with GeForce 9500M GS.
When I connect Sharp LCD FullHD 32" TV to HDMI port of my laptop and CRT AOC 16" monitor via DisplayLink adapter DVI to HDMI, the refresh rate of CRT decrease to 60Hz.
Only CRT connected via VGA port to laptop can operate on 1280x1024px and 85Hz but via DisplayLink only 60Hz which isn't quite comfortable.
I tried these drivers:
DisplayLink-5.2.23219.exe <- brought with CD
DisplayLink-5.6.31870.exe
DisplayLink-6.0.34621.exe
DisplayLink-6.1.36490.exe
DisplayLink-6.1.36486.exe <- via Windows Update
DisplayLink-6.2.37116.exe
USB2HDTRIO_XP_7.zip <- from i-tec website
but always the same problem.
I found these topics:
http://www.displaylink.org/forum/showthread.php?t=596&highlight=refresh+rate
<- this is related to the issue, closed but don't fixed.
http://www.displaylink.org/forum/showthread.php?t=1227&highlight=refresh+rate
<- this is related but with no answer.
I tried uninstall the drivers, restart, install the other; update driver manually.
Why the refresh rates higher than 60Hz isn't supported by the adapter?
