@alikatado88 i had a similar effect with a bad HDMI-Cable.
Is the one you use with your 55" the same one that you used with the PC-Monitor?

@aerosheik I'm with the same issue using the RP4 and I just can see the boot secuence until the RetroPie logo in my CRT TV appears and then I lose signal cos probably Emulation Station has another resolution and is not the same as when the system boots.

Di you fixed or is impossible use RP4 with Retropie in a CRT TV using HDMI to a components transcoder? With a RPZero I can do that wihtout problems just changing the hdmi_mode and group like this:

hdmi_mode=1
hdmi_group=6

But I still can't use my CRT TV under Retropie with a 480i output and idk what can I do right now.

@mitu yeah i saw that on the raspberry pi fourms. I set it to that already, and nothing happened.

@Spectreman said in Output to AV with the 3.5mm jack:

I had read that the Raspberry outputs to the 3.5mm jack if no HDMI is connected.

Not on a Pi4 - where the composite video output has to be specifically enabled.

@DavidDraper the setting you're looking for is aspect ratio, and you want it set to the default of 'core provided'. it's in the video settings.

however, i would caution against setting things via retroarch unless you know exactly what you're doing.

@mitu Found it, and it works. Now I just have to locate the option to save this config for each individual game instead of every game...

That's it, thanks.

Thanks, Isn't it strange that with no SD card inserted it comes right up on the TV? Thats what has me so confused and it used to work fine on my RCA TV. I never have been able to get it working on the Bravia or Samsung. I had done that before, but I used Escher. MAybe that's the issue. I'll flash with the official one.

Appreciate the help.

Turning down the gamma to "0.5" has made a remarkable difference. What a strange default option in RetroArch! Thanks to everyone who threw in their $.02

@drmaxwell Are you using RetroPie ? Please give more details about your setup - https://retropie.org.uk/forum/topic/3/read-this-first.

@iamtyce @DougA I finally managed to solve the problem with an HDMI splitter and an HDMI-to-VGA converter. 😄 The latter doesn't change the resolution, but my projector accepts the analog signal in contrast to the digital HDMI signal, which it refused as "unsupported". I just had to adjust the picture a bit via the projector's controls, as it was slightly off to the left and only partly visible.

A mentionable obstacle was that only one out of three HDMI splitters I tried worked with the 1600x1200 pixels DMT signal from the Pi. The other two only accepted CEA signals (see HDMI mode options in the official Raspberry Pi documentation). Strangely enough, all three splitters look exactly the same from outside apart from the brand logo.

This is the splitter that worked:

And here's the converter:

(Links go to Amazon Germany, but the non-Germans among you may at least learn the brand and model of the devices from them.)

thanks !, yes I mean emulationstation

@xc-3730c as detailed in the read me first page we don't support 3rd party images.

Done! Thank you. I was trying to find a formatted text tag like that, but couldnt locate one.

By the way, video signal on cps2 arcade machine was indeed 16:9, but the rendering was on a 4:3 screen. Rendering cps2 games as 16:9 is a bug, it was fixed on lr-fbalpha in late 2015, and was backported to lr-fbalpha2012 a few months ago.

About using the old lr-fbalpha2012 because you got the wrong roms, why not update your roms instead ? If you buy the wrong tire for your car, do you buy a new car or do you go back to get the right tire ? I can understand using lr-fbalpha2012 on a raspberry in a few specific cases (i'm mostly thinking about svg and killbld here), but lr-fbalpha is overall better because a lot of bugfix and compatibilty was added in the last 5 years.

Long time i used a LCD screen, has build an upright cabinet for it, spent hours and hours to find nearly realistic shaders... but at the end i use an old crt. So there are no latency problems cause of upscaling, no stuttering, and the result looks fantastic ;-)

@ecks, just tried it on a GBA rom. All three emulators and an assortment of 5 or 6 resolutions all give me the same problem with no changes.

@Kecha Glad it worked out! Have fun!
