Hi there. first sry for bad englisch .
I have an AMD Radeon R7 370 MSI with 2 DVI ports and 1 HDMI port. I Connect 3 Screens: 1 with DVI cable, 1 with DVI to VGA adapter and a VGA Cable and the last HDMI port with a HDMI to VGA Adapter and a VGA cable. The last one is connected to an old TV-Screen with an VGA connection. The TV-screen can handle 1024x786 60Hz, but i can't change the Hz value with Windows 10 (x64) or with the Catalyst Control Center (Crimson Edition 16.1 Hotfix). In the applications i can see a Max from 1920x1080 85 Hz from the TV-screen but it can't be true. Before, i try the Application with Catalyst Control center(15.07) but if i change the Hz to 60 its still 75Hz and nothing happen.
Hope you guys can help me.
