Hi, I'm the owner of Lo-tech and creator of this board. Thanks for the OP and others for their interest in this board. Distribution is indeed done through TexElec now. However, if there is interest in a group buy then I would be very happy to facilitate this for EU buyers. We could also look at adapting the header although that would of course increase lead times.

For now my conclusion is this: Progressive scan with RP4b still works. You just have to either set it in config.txt as the appropriate sdtv_mode (16 NTSC/18 PAL), but then Emulationstation will also be in 240, which looks terrible, or use tvservice to enforce it on a per rom/platform basis after retroarch starts to switch back and forth. You can use my watcher python script and run it on startup in the background and then make an appropriate runcommand-onstart script or make your own solution.

Setting the progressive scan bit in the VEC (Composite TV out) register set: https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/vc4/vc4_vec.c#L104 B. Remove the interlace flag for the mode: https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/vc4/vc4_vec.c#L256 tvservice does essentially the same thing and sets the new modes: https://github.com/raspberrypi/userland/blob/2448644657e5fbfd82299416d218396ee1115ece/interface/vmcs_host/vc_sdtv.h#L60 https://github.com/raspberrypi/userland/blob/master/host_applications/linux/apps/tvservice/tvservice.c#L703 https://github.com/raspberrypi/userland/blob/master/interface/vmcs_host/vc_vchi_tvservice.c#L1213 https://github.com/raspberrypi/userland/blob/master/interface/vmcs_host/vc_vchi_tvservice.c#L698 Since there is a hardware flag that needs to be set, it won't be possible to resolve this with xrandr modesetting alone as was suggested. Ideally RetroPie in some form could enforce this natively in a similar fashion by taking the SDTV_MODE as a parameter and enforcing it through VCHI like tvservice does, alongside the modsetting being done in the modified SDL library.

@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+

@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 .. https://www.ebay.com/usr/linuxbot3000?_trksid=p2047675.l2559 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 .

If you have a bit of spare cash (~40EUR) get this: http://arcadeforge.net/Pi2Jamma-Pi2SCART/PI2SCART::264.html or this http://www.rgb-pi.com/ 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. https://www.reddit.com/r/crtgaming/comments/abt1fv/240p_composite_to_crt_tv_artifacts_blurry_text/

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.

@Sakitoshi Hello There are a number of sony playstation games in the PAL region, an image with large black bars at the top and bottom. Please tell me exactly where in retroarch, in which section which line to set the value to 512. Thank you so much.

bumping this one myself as I'm trying to do the exact same thing. i tried if, then, fi but i'm a total script noob so i'm sure my syntax is crap trying to achieve the following onstart if system = "system name" then do-a-thing fi anyone that can help?
