Amiberry 3.3 / RPi 4 slow

@mitu Tons... it’s over 50 of them.

I tried setting 87-15 and 87-17 as global Amiberry modes, no change.

For the record, I’m back to the 1x16 setting in the config.txt. Not that it changes anything.

Is looks like your TV is upscaling everything to 4k ? Try setting
just

hdmi_safe=1

into config.txt and see if it boots to a different resolution. Does the TV have a 'Game Mode' you can turn on ?

[gordonfreemanjr]

@mitu Yes, the TV has a Game Mode. If hdmi_safe=1, should I also uncomment the group/mode settings?

[mitu]

@gordonfreemanjr You can comment out the custom video mode and try with just hdmi_safe.

[gordonfreemanjr]

@mitu Um, no. With this setting on and the custom modes commented out, the ES won’t boot.

Also, the terminal window looks like this:

Ok, so the hdmi_safe works, but for some reason ES doesn't start.
Can you run emulationstation --debug and post the \\retropie\configs\all\emulationstation\es_log.txt to pastebin.com ?

[gordonfreemanjr]

@mitu Sure. Here:

@gordonfreemanjr The log shows no error related to the video and a proper showdown.
I just tried the same thing on a Pi4 and EmulationStation starts ok - albeit in 640x480 @ 60hz, forced by hdmi_safe. Does your TV shows the change of resolution when starting ?

[gordonfreemanjr]

@mitu I’m not sure about showing the change of resolution, but when I power the Pi up with the new settings, apart from the black screen and the ES not booting, when I press the HOME button on the Smart TV’s remote, the following info is displayed:

HDMI 1
Game Mode
640x480 / 60p
SD
the date and the time

This seems right, similar to your screenshot. Why ES doesn't show up, that I cannot explain - didn't found this situation before.

[gordonfreemanjr]

@mitu Still, when the Pi is blackscreened at the start up, that is when the ES doesn’t show up, the F4 key works and brings the terminal up. As far as I’m concerned, this the expected behaviour when quitting the ES.

It’s almost like the ES was booting after all, just hiding behind the black screen for some reason.

[dankcushions]

@gordonfreemanjr i don't know why it would make a difference, but could you try with the default theme? and/or updating emulationstation to latest master (update from source)?

[gordonfreemanjr]

@dankcushions I like this suggestion. I’ll try that later today and get back to you. Thanks!

[gordonfreemanjr]

@dankcushions Both methods have failed. Same situation: black screen on startup, even with the preset theme and the ES script updated from source.

[mitu]

@gordonfreemanjr One last idea (filtering out 4k modes at the source) - add to config.txt:

[hdmi:0]
hdmi_max_pixel_freq=200000000
[hdmi:1]
hdmi_max_pixel_freq=200000000

Remove the hdmi_safe option and comment out the hdmi_group/hdmi_mode options (if still enabled).

[gordonfreemanjr]

@mitu Ok, so the „safe”, „mode” and „group” options are now commented out, and the „pixel freq” options are on.

The ES boots fine. The HOME button on my Smart TV remote displays the following info:

3840x2160 / 30p
UHD

[mitu]

@gordonfreemanjr said in Amiberry 3.3 / RPi 4 slow:

UHD

Based on the information above, I guess the 4k video modes aren't filtered. Can you post the config.txt with the latest modifications ?

[gordonfreemanjr]

@mitu Sure. Here:

@gordonfreemanjr The config looks ok. The only think that's a bit different than the stock config is enable_uart(added by a shutdown script maybe ?), but that shouldn't affect the video resolution stuff.

[gordonfreemanjr]

@mitu I just called Samsung and they confirmed that upscaling the resolution is what a Smart TV does and there’s no internal setting to change it.

...

Still, when I connect the Pi via HDMI, the TV asks me what kind of equipment it is. I usually pick Game Console. Maybe I should ID the Pi as something else to avoid the upscaling? A decoder? A toaster?

At the same time I find it weird that I’m the first RPi4/Smart TV user to encounter an error like this one.
