hdmi to component CRT Help..runcommand

MrCoffee

@mitu thanks I'm new here, don't know how to do that yet.

@MrCoffee The posts are formatted with Markdown - https://commonmark.org/help/. I just basically added some ``` and leading spaces to create code blocks.
There used to be a help link shown when you typed a reply/created a new topic which pointed to that help page, but I see now that is gone. Probably removed by a forum software update.

@mitu Bookmarked thank you .. :)

@MrCoffee if 3 backticks on the line above and the line below your code isnt possible to do on a device your on, you can leave the line above and below your code blank and indent your code lines 4 spaces.

Is there a way to define the syntax highlighting like that? eg. bash, c, xml

MrCoffee

@Efriim lol thats looks cool ,, kinda like fortune cookies in my linux terminal.

Yes, you just add the name of the highlighter after the code block start
```xml.

@Efriim lol nice. I'am saving that one.

Cool video. You’ve got all the solutions I’ve been looking at. Which would you say you prefer? Vga666 to component? Retrotink component? Aliexpress HDMI to component?

MrCoffee

@mukelarvin Well what i use in the video is the cheapest, but as of late I've been using a VGA to Component transcoder, theres a 15khz distro of retropie that someone made that works like a dream. they use some kinda data base for the customs timings, but I do like the RetroTink, its less of a mess when it comes to wires, but its about 90 bucks and needs some time to set up.

So the HDMI to Component is kinda the poor mans way but it does work , it has its small problems , overall its a good starting point .. 12 bucks + 5 or so for the cables.

for the vga666 i think i got mine on ebay for like 12 bucks and the transcoder is like 50 ish now..But its a mess of cables however with the right distro it's what works best for me, most of the arcade games run at the right rez. Retropie CRT Edition.

keep an eye on this guy.He sales vga or scart to component transcoder's ..

As far as the Retrotink goes its just the cleanest after setup, less cables and less of a mess. I've trying to get that RGB-pi working with it .

I am trying to get an HDMI to Component converter (no scaling, 480i compatible) working with a 27" Sony Trinitron 27FS13 (480i/240p) on a pi4. It looks something similar was done here. I can start a new thread if that makes more sense, but this seemed to be the most recent thread on this topic. Is anyone up and running on a CRT over component on a pi4 using the method here? @MrCoffee, should your method here still work? Is there a more up to date guide for accomplishing this with current hardware/build? Thanks for any feedback.

@PUME04 no it doesn't work , you can't switch res with tv service , it's broken , the fmks video driver on the rpi4 was made by people who hates crt monitors and cabs ;)

The same 'people' added support for video resolution switching to tvservice in the first place and also added support for 240p for analog video, so I think your comment is out of place.

myzar

@mitu i was simply joking , but framebuffer support is such a basic stuff that is amazing that is still broken , and without anyhope to be fixed since the new kms in 5.4 is broken in the same way.

It's not a priority and no one cares, that's a fact :)

P..s the vc4 driver is not made by the same people who coded dispamax

I do own a Pi4 now but I haven't had the time to have a go with it. I have used this method on a pi2-3-3b+ and it works fine.. I keep seeing out on reddit that people have gotten a retrotink and RCA out up and going @240p but there some problems with slow down or resolution switching .

I hope its just something that could be fix , they did add 240p to the pi at a later date if i remember correctly..

myzar

@MrCoffee 240p output works fine btw , but you can't switch res , you are stuck with the res you boot in config.txt

There's nothing to be 'fixed', the Linux framebuffer under KMS doesn't support resolution switching, it's up to the application to do the modesetting, using the Linux DRM API.

It's not a priority and no one cares, that's a fact :)

I encourage you to read the technical reasons why tvservice doesn't do resolution switching with the KMS API and why it's not going to be 'fixed'. Stop spreading FUD.

myzar

@mitu what kind of fud i am trying to spread ? that they hates crt was only a stupid joke. That tvservice is broken is a fact reported over one year ago, that they don't plan to add a workaround is a fact , people buying a rpi4 and planning to make a system with pixel perfect res should be aware of that. Also is not true that it works if the app does the tv service work, advmame who does that and who used to work until march i think doesn't work anymore.
The direction in dev doesn't seem good for crt/cab users , i don't know if you are aware but the vga666 overlay is totally broken in the new 5.4 kms drive.

Anyway peace this wasn't supposed to be a flame or trolling :)

Thanks for the info everyone. I picked up a 3b+ for the arcade and I'll save the 4 for a future project. Didn't mean to open a can of worms. ;-)
