Garbled Colors on Sony Trinitron

[iamsiincere]

Hello. I've tried following the instructions exactly how they were laid out. I'm using the RetroTink Ultimate and component cables on a Raspberry pi 3B+. I've updated everything and still end up with very bad colors. I also made sure that dpi_output_format=0 was correct in the config file before starting the process. Any help?

hi! i'm sorry that it's taken a bit to get back to you, i've been on a computer sabbatical for the last 4 months.

is this a retrotink ultimate sold by mike chi or is it one of the newer ones?

try this:

go into the retropie menu in ES, select RetroCRT. Once in there, select the correct hardware for your system. the colors are probably because it defaults to VGA666

Hey, thanks for the reply. I think it was sold by Mike Chi. I bought it back in 2017/2018 (I don't fully remember the date). I'll try that once I get a chance. I need to create a new image (no idea where any are for the retrotink ultimate anymore) before I can test that out. Currently, I'm retrying my hand at creating a retro pc that uses groovymame, outputs vga, using a vga to component transcoder, then outputting component to my Sony Trinitron. Tried it years back, failed and I plan to try again.

Disregard part of what I said early, I forgot you have that image.

Morning. Thanks again for your input. Before when I used to set this up, your instructions wouldn't have worked but I think enough updates were made that it worked 100% with the instructions provided.

Side question...Any plans to get retrotink ultimate to work with RPi4? Honestly I mainly wanted RPi4 to output component for the N64/Saturn/Arcade emulators. RPi3B+, as far as I know, is terrible when it comes to N64/Saturn. So for now, I'll be using this strictly for arcade games (I also have a MiSTer for the 16bit consoles).

I spoke too soon. It worked, then randomly as I was removing and adding cores the color went back to being garbled. Here is my set up and my current config.txt settings: TV - Sony KV-27FS13 Raspberry Pi - 3B+ Retrotink Ultimate Retrotink Ultimate Component output to TV Component input Image - RetroCRT-20200108-rpi3 I also tried the setting change within your instructions (You'll need to update /boot/config.txt and set the following to 519 for RetroTink & 0 for all other platforms. "dpi_output_format=0")

sadly, i don't have any real plans to support RPi4 at this time. i bought one when they first came out to port everything oer to it.

I haven't experimented yet, but my understanding is that you can't do dynamic resolution changes... so i wouldn't be able to switch between 320x240 for ES and then 1920xNNN for the games... if ES had the ability to stretch & not scale for menuing, it'd work out ok since the user wouldn't notice anything

oof, that's something i don't have an answer for. maybe a loose connection between the pi & rt?
