lilis,
да, сейчас посмотрел - у ViewSonic совершенно иное содержимое установочного пакета (inf-файлов и профилей в явном виде нет).
Неподписанный драйвер, при отсутствии в системе монитора ViewSonic, выдает такую инструкцию:
NOTE: For your convenience you can print these instructions by pressing the Ctrl and P keys on your keyboard.
1. Click Start on the Windows taskbar, type "devmgmt.msc", and press Enter on your keyboard. On the User Account Control screen, click Continue. The Device Manager screen will display.
2. On the Device Manager screen, click "+" (preceding Monitors).
3. Right-click Generic PnP Monitor and select Update Driver Software. The Update Driver Software menu will appear.
4. On the Update Driver Software menu, select "Browse my computer for driver software" and select "Let me pick from a list of device drivers on my computer".
5. On the Update Driver Software menu, click Have Disk, type "c:\viewsonic" (where "c" is the boot drive), and click OK.
6. Select your monitor and click Next.
A warning message may display "Windows can't verify the publisher of this driver software." Please ignore this message and click "Install this driver software anyway."
After the wizard has successfully installed your monitor, click Close.
NOTE: The above instructions are also available on your computer in the "viewsonic" folder.
