HDMI to VGA Adapter VGA CRT Monitor Not Working VGA Scaler Scandoubler
Hello,
I have one Mister hooked to a VGA CRT monitor via an HDMI to VGA adapter / converter. The quality is just incredible and all the cores are working great except for the PSX one. I do have another Mister with the IO hat with VGA output, but the quality is not as great and I want to keep that one on my main CRT tube TV. I really want to focus on a solution for the HDMI to VGA adapter which is also cheaper and more accessible.
I know that Scandoubler is not support because of the funny resolutions switching in some games and interlaced ones and the output signal frequency is 15.7 Khz and it's not supported. VGA CRTs expect 31Khz frequency.
I opened an issue with PSX core dev on Github and the answer/solution was to use VGA Scaling. I have tried doing so without luck. The signal is still 15khz no matter what I do.
Anyone here had this issue and could help please? I will for sure do a Youtube video on it after if I can get it to work. I see many posts with no clear instructions with people in the dark like me. One of them suggest to output at 960p the PSX core video mode (where 480i X 2, which makes sense). I've tried, but it just won't do it. What is the secret sauce? Here is my Mister.ini file.

; Background picture will get darker after double timeout
; 1 - enables the recent file loaded/mounted.
; WARNING: This option will enable write to SD card on every load/mount which may wear the SD card after many writes to the same place
; There is also higher chance to corrupt the File System if MiSTer will be reset or powered off while writing.

; Set to 1 for automatic HDMI VSync rate adjust to match original VSync.
; Set to 2 for low latency mode (single buffer).
; This option makes video butter smooth like on original emulated system.
; Adjusting is done by changing pixel clock. Not every display supports variable pixel clock.
; For proper adjusting and to reduce possible out of range pixel clock, use 60Hz HDMI video
; modes as a base even for 50Hz systems.
vsync_adjust=0
; If you monitor doesn't support either very low (NTSC monitors may not support PAL) or
; very high (PAL monitors may not support NTSC) then you can set refresh_min and/or refresh_max
; parameters, so vsync_adjust won't be applied for refreshes outside specified.
; These parameters are valid only when vsync_adjust is non-zero.
refresh_min=0
refresh_max=0
; These parameters have the same format as video_mode.
; You need to supply both PAL and NTSC modes if you want vsync_adjust to switch between
; predefined modes as a base. This will reduce the range of pixel clock.
