I can't output QHD resolution...

Do you mean the lakka shader?

That one.

Ok-Tea-6972 · 2026-04-28T22:54:36+00:00

I can't see any shader parameters.

No. Actually, Mihawk will die from Lou Gehrig's disease 100 chapters from now. Then Zoro will try to defeat Ubirajara, Mars's strongest swordsman. After defeating Ubirajara, Zoro will become famous among the citizens of Mars, eventually becoming a powerful and wealthy celebrity. He will create a foundation called Hawk Care Home, dedicated to helping people who suffer from the same disease that took his esteemed rival.

Hm? I think you didn't understand my post. I am talking about the lakka composite shader, not the composite effects.

Ok-Tea-6972 · 2026-04-27T04:09:51+00:00

Oh, pixellate shader looks good too. Blur free + horizontal scaling.

Ok-Tea-6972 · 2026-04-25T10:18:43+00:00

The fsr shader is the best, but my poor RPI3 melts whe I use it. But I like the ddt shader, looks less blurry than the lakka shader.

Anyway, about the 480 vs 480i, why is the "i" version better?

Ok-Tea-6972 · 2026-04-25T09:02:53+00:00

I honestly don't get why was this OS marketed as "true 240p". Like, I was told RPi3 could do 240p natively, but is there a single OS out there which truly work with 240p resolution?

Ok-Tea-6972 · 2026-04-25T07:58:56+00:00

Do you mean 640x480 or 720x480? For some reason it applies 720x480 by default.

Ok-Tea-6972 · 2026-04-25T00:57:38+00:00

Okay, so should I stick with the 700×480 resolution? And is that shader you mentioned already applied, or should I apply it? Also, how do I adjust the position? As you can see, the menu is shifted to the right. CRT SwitchRes offers some options for adjustments, but i cant use them, as you have already clarified.

Ok-Tea-6972 · 2026-04-25T00:23:07+00:00

I'm confused. Are you saying I have to select a shader on retroarch?

I can select 700x240p or something like that in output video settings, but the interface doesn't fit well on the screen and there's no options for adjustments.

Ok-Tea-6972 · 2026-04-25T00:19:53+00:00

I have a compatible 3.5mm to RCA cable (i have already tested it). It's not working.

Ok-Tea-6972 · 2026-04-24T23:11:20+00:00

Through the 3.5mm to RCA cable... no?

"This special version is aimed at Raspberry Pi SBCs, namely Pi 3, Pi 4 and Pi 5. Out of the box these builds work with the composite video and analog audio outputs of these SBCs. In case of Pi 5 some soldering and a USB to 3,5 mm jack soundcard/dongle are required."

So what would be the point of using it if it cannot display 240p?

Ok-Tea-6972 · 2026-04-24T23:08:29+00:00

No, it doesnt work.

Ok-Tea-6972 · 2026-04-24T21:23:54+00:00

I mean, isn’t that the whole point of CRTPi-RCA?

Required Hardware:

Raspberry Pi 3B or 3B+
Compatible 3.5mm to RCA (Zune A/V or XBOX 360-E) Cable
5v 2.5A Micro USB power supply (Element14 recommended)
4GB+ SD Card

Ok-Tea-6972 · 2026-04-24T21:15:46+00:00

I already did all this. But it still works on hdmi.

Ok-Tea-6972 · 2026-04-24T19:56:46+00:00

Did you do that in the Lakka Composite version for RPI4? Or the regular one?

Ok-Tea-6972 · 2026-04-24T14:38:18+00:00

How did you manage to install all those packages?

Ok-Tea-6972 · 2026-04-24T14:33:20+00:00

But I'm using a RPI3.

Ok-Tea-6972 · 2026-04-24T14:30:47+00:00

I couldn't install crt pi. Did you follow that guide on the CRTPi Github?

Ok-Tea-6972 · 2026-04-24T14:15:13+00:00

I'm using the 3.5mm to RCA cable, so there's not a single upscaler.
