MiSTer FPGA Forum

Im at a bit of a loss, I cannot get my HDMI out to my VGA monitor at all.

HDMI works fine using regular TV.

This is my mister config.

Im totally stumped, ive tried a variety of HDMI to VGA convertors, I have had it working in the past but for the life of me i feel ive tried everything but im sure im missing something stupid.

Ive tried direct video 0,1, hdmi limited 0,1,2, vga scaler on/off, scan doubler on/off.

video_mode=5

; set to 1-10 (seconds) to display video info on startup/change
video_info=3

; 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

vsync_adjust=1

; 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.

I broke it too once after fiddling around too much. I ended up throwing the ini away and starting anew. It worked right away, then. Direct video 1 and vga scaler 1 is the only thing I changed from default, I believe.

The reason could also be your HDMI to VGA convertor. I have 4 of these and only one works.
What is your exact setup? This is my setup:

HDMI to VGA converter > VGA to Scart cable > Scart Adapter Breakout cable to BNC > Sony BVM

video_mode=5 why?

try:
video_mode=6
vscale_mode=1
fb_terminal=1

also it should work with vsync_adjust=2


i reported on github some sync issues with hdmi to vga with the 3 latest main releases too but i was able to fix my sync issues with composite_sync=0

That was just the last mode i tried, ive tried them all

Ive ended up using a VGA adaptor, but i lose a bit of colour on my TV And monitor using this, would love recommend a good VGA splitter recommendation, ive gone through 3 so far and the only one that actually displays anything at all is the cheapo one i got from amazon.

HDMI to VGA cable straight to monitor.

Ive also tried a regular HDMI cable with a VGA to hdmi convertor (ive tried two seperate ones )

Literally tried everything i can think off, so it must be cable related.

Could you please share some details of the stuff?
And your init file?

I've searched for hours this solution!!! Front-page it!

Thanks×∞ Roel27
This is my final setup:


Tips:
A. You need to power the hdmi to vga converter
A.1 You may need some extra Amps for that (not may case), so the Jetson Nano PSU could be nice, or anything with a Jack ED 5.5mm ID 2.1mm, 5v, 3,4,5 amps should work
B. You do NOT need full sync (CSYNC), just HSYNC is enough, after that set extenal sync on your PVM, MVM or BVM. Let the other cable hanging on, it will be fine, 3BNC+CSYNC are hard to find, go for classic 5BNC conectors cable at least on France, EEUU may be different
C. As you said, at mister.ini file in root folder (commented by default or just inexistant in my case):
composite_sync=1
direct_video=1
made a difference

Cheers
