How to change display res?
#1
Im having some trouble with setting display res.
My project is using a 800x480 60hz lcd (the usual 40pin DPI) and a tfp401 based decoder.
Ive also tested on the adafruit board i can only display uboot at the correct res.
The moment linux starts the screen just goes black... Im assuming linux is ignoring the EDID data on the display board.

When its connected to my main monitor im unable to change res inside the armbian gui. Theres only 1 res listed. So how do i get this to follow the EDID res rules so when I plug it to my dev board it displays correctly for that panel and when set to my monitor it displays at the native res there too...

It appears to be stuck in 720p mode when i run it on my monitor. And my monitor freaks out with timing error warnings when i change res through the retropi menus...

So how do i do this? How do i make the orange pi in all the front ends run the display based on the edid settings?

h3disp -m -800x480 -d worked... sort of, there still seems to be a timing issue as theres some hotizontal distortion and flickering

Right it seems i fixed it all...

Well mostly.

The issue is actually the kernal used in retroorangepi being so out of date. I didnt realise this at the time, I build new SD card with latest armbian 4.19y and all my display worked right off the bat. The kernel read the edid and set the display accordingly.

Thats not the end of my problems though. I seem to have lost bluetooth and my usb has become unstable. These are new things to fix. But i wonderd.

If i installed orange pi 4.2 how do i go about updating the kernel?

unfortunately not possible (at least in a straightforward unpainful way). Mainline kernel has its own ins and outs, new libraries, we're working on it now. It won't take much longer, beta testing will begin shortly

well in terms of donations i cant help there. im jobless and poor...
Support wise i can give you a full mention on my project build video?

Im in no way a big channel but i do have a few people who follow my builds. And even have a fair bit of interest in my current retro handheld i want all this for...

Would that be enough to get access to the beta?
