Hi and thanks again for everything.
I have a Dell / AMD low-profile dual-port (DP & DVI-I) R5 240 card and it's driving me crazy.
The CRT is JVC DT-1710 tri-sync. It works well in Windows at 31kHz at the DVI-I port with a VGA adapter through a VGA-to-BNCx5 cable.
I follow the standard CRT Emudriver for HD5450 guide and pick Arcade tri-sync. No matter my LCD for setup is at DP or DVI-I, after enabling EDID emulation for the analog_0-VGA output and swapping in the JVC, the JVC reports out of range (not "no sync"). I assume the card now should output either 15kHz or 31kHz at the DVI-I port. What strange is that even I swap the LCD back on the DVI-I port the LCD has no image. I always have to fall back to the DP port. Plugging the LCD back to the DP port shows the 1080p desktop. And at the same time, the JVC would pick up the sync and displays the extended desktop as a second monitor at 31kHz
DP with LCD at 640x480; DVI-I with the JVC at 640x480 (have tried duplicate, extended desktop, made the JVC the main display), once I unplug the LCD, the JVC would go either out of range or no sync. Replugging the LCD at the DP port, the JVC goes back on.
And another finding: both Windows Device Manager and the CRT Emudriver installation reports that the display adapter / compatible devices is "AMD Radeon(TM) R5 240 (CRT Emudriver)", but in both VMMaker and Arcade OSD it is "AMD Radeon R7 200 Series" instead ...
I've tried everything for days and man ... I need a break. For now I can only resort to my older HD 8490.
Has anyone experience something similar? Is it an unsupported card somehow or something? Please help! Thanks!
