MiSTer to Consumer CRT Direct Video RGB SCART Output Issues

Unread post by retrofan01 »

Just hooked up my MiSTer with Digital I/O Board 1.2 to my Panasonic TX-14S3T PAL CRT via Direct Video using a HDMI to VGA converter and a VGA to SCART cable purchased from UltimateMister.com but I'm getting a garbled output on the main menu:

My video chain is MiSTer > HDMI to VGA Direct Video converter > VGA to SCART cable > Panasonic TX-14S3T. direct_video and composite_sync are both set to 1 and the TV works fine with other consoles connected via RGB SCART in both 50 and 60Hz. My mister.ini file is below:

Code: Select all

[MiSTer]
key_menu_as_rgui=0     ; set to 1 to make the MENU key map to RGUI in Minimig (e.g. for Right Amiga)

Any ideas what might be happening or is there anything I've missed?

Your config seems ok. Looks like maybe you have Scandoubler Fx option enabled in the OSD. Can you check it using an HDMI panel?

EDIT: I've just tried your config and it's not working on my setup, but I can't put my finger on as to why - maybe somebody else can see it. In the meantime, you can grab a fresh mister.ini from here and just change direct_video=1 and composite_sync=1, this should work.

Where can I find the option to disable Scandoubler FX for the main menu? I've not got as far as getting into any of the cores.

Scandoubler could be a residue if you have used it on HDMI previously, but anyway, see my EDIT above.

What's the difference between this cable (I noticed the description specifically says that's it's not for use with MiSTer) and the one from UltimateMister.com?

Well to be honest the Spectrum Next cables should be the same. Are you sure that your TV is in RGB mode?

Don’t worry that I sort out this with him.
Yes the cables are the same and we also produce them for our Next / NGO board.

It’s already sorted. Tv configuration fixed.

Yes all I had to do was cycle through the inputs on the TV from VCR to AV even though the TV only has the one SCART socket and no built-in VCR. Shows how long it is since I've used a CRT :lol:

Thanks Ricardo and everyone for your help!

Thanks mate, I was about to say it's definitely not the cable since I've personally tested a lot of your ones and they all work just fine ;)

Yeah, checking the absolute basics is usually a good idea, but since OP said they have already used other consoles on this TV I thought changing to AV was covered already.

One question remains: why me copy-pasting and using OP's mister.ini posted here breaks my display? It's bizarre, because there is nothing wrong with the ini itself. Something about text encoding?

Possibly newline encoding. MiSTer.ini uses carriage return and line feed control characters (like Windows), whereas Linux uses just uses line feed. If you were pasting into a new file using Nano via SSH for example, you would get just line feeds.

Yep, this seems to be the case. Good to know about this quirk for the future. I usually either edit inis on my desktop or directly on MiSTer, and that works fine, so this here today threw me off.
