Hello friends. Here's a weird issue I'm having with my Sega New Net City + Windows 10 PC setup.
When booting the PC from the powered-off state, the bios screen and Windows loading screens all display correctly, but when it gets to the Windows sign-in screen, the 640x480 60Hz desktop resolution is displayed in a thin scrambled strip across the middle of the screen. See attached image.
I can fix it by following these steps:
- Use my secondary monitor to go into Windows Display Settings
- Change the resolution of Display 1 to one of my super-resolution modes
- Change the resolution of Display 1 back to the 640x480 desktop resolution
- Restart the PC
After restarting, everything works fine. Windows starts up and the monitor in my cab displays the Windows sign-in screen at 640x480 perfectly. After that, I can use all my emulators without issues.
But the next time I boot the PC from cold, I'll have to repeat these steps again. I don't understand why it works after a restart but never from a cold boot. Any ideas on how I can fix this?
My setup:
- Sega New Net City with Toshiba PF29 tri-sync monitor
- Windows 10 PC with Dell AMD Radeon R5 240 flashed with ATOM-15 tri-sync ranges
- The arcade cabinet monitor is set as primary display 1 connected via DVI with VGA adapter to the R5 240.
- I have a CRT PC monitor as a secondary display connected via VGA to Intel integrated graphics.
- Windows display settings set to "extend desktop" across both monitors
- I followed the guides on Calamity's site for setting up CRT Emudriver + VMMaker using the tri-sync preset + super-resolutions + EDID emulation
- I've attached my user_modes.ini file (saved as a .txt file for this forum) and a log.txt file from VMMaker.
Let me know if there is any other information needed to help troubleshoot this odd problem.
