Finally I've found solution for my tv there - tweakvec, and now got true correct colors with this tool.
Maybe it will useful for somebody too....

@mitu that make sense .. thanks for the help.

Anyone have any experience with this board? It's interesting to see a VGA hat that supports 24 bit colour, was hoping to find someone that has done some kind of comparison between this and other solutions (VGA666, HDMI->VGA converters, RT Ultimate, etc).

A simple workaround is to delay the tvservice call in runcommand-onstart.sh , e.g.:

#!/bin/bash echo "starting emulator "$2 >&2 if [ "$2" == 'lr-fceumm' ]; then sleep 5 && tvservice --sdtvon="NTSC 4:3 P" & fi

@WeirdH said in Best Monitor/TV for Full Size Arcade Cabinet:

Note that you will still see black bars on a screen like this when playing vertical games (Donkey Kong, Pac-Man, Dig-Dug, lots of shmups)

… that you can fill up with overlays like these. 😎

@jamesfarnhamlong said in Retrotink U - Higher res ES and PSX games:

The 450x270 looks best, but I was wondering if it was possible to run one @ 720x578 to improve the picture a little. I know the TV supports this as I have an old Apple TV that uses this revolution. How do I write the hdmi_timing to make this work? Is there a calculator or something I could use?

Try this - http://eightvirtues.com/lakka/hat/RPi HDMI Timings Calculator and Core Docs.ods (courtesy of https://www.youtube.com/channel/UCtF_2HGXXPlUi1J0Euw1Qrw).

Is it possible to adapt this to run at 2x resolution so I can use the enhanced graphics in psi-rearmed. Is there a way to have this only affect psx game launching? Or would it then throw out all the other systems? Is there much point?

Maybe if you use the calculator linked above you can derive the correct HDMI timings to use. As for the effect on the other systems, you'll have to ask the author of those configs.

The config is the same, it does not matter if its pvm, monitor or consumer. You will possibly still need some tweaks , depending on your TV (to center the picture). That guide is quite old and so may be the timings he listed. I recommend looking at RGB-Pi or Retrotink configs on github, they're more up to date and work with Gert as well.

@Deityfierezy you are better for now with the 3+

@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 ..

These are dedicated RGB solutions for SCART TVs. No lag and 1:1 amazing picture quality.

Thanks guys. I posted on Reddit and they suggested messing with the service menu. And I got it better by modifying the c-trap setting.

update:

removed CRT theme renamed "HD" theme added grid view

the CRT only theme is now unneeded so I removed it and instead renamed the "HD" one and added grid view.

Hello)
Could you tell me how ( if it possible) to run raspberry in PAL mode (sdtv_mode=2) with all emulaters configured for NTSC ?
