hdmi to component CRT Help..runcommand
-
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
tvservicein the first place and also added support for 240p for analog video, so I think your comment is out of place. -
@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..

@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
tvservicedoesn't do resolution switching with the KMS API and why it's not going to be 'fixed'. Stop spreading FUD. -
@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. ;-)

@PUME04 lol no problem, you may want to google "Retropie CRT edition" I've been using that with a pi 3 and a vga666 into a vga to component transcoder .. yes you will spend a bit more money but it works so well ,, but you can not do 480i ,, but its set up to handle all the wacky arcade resolutions per game all done from a config file.
this is the transcoder .. well hes out of stock but keep an eye on him.. about 50bucks

and I use this type of vga666 works really well ..
