Looking for a CoreElec device capable of 1920x1200 resolution

hbs · 28 December 2022 16:46

Hi.

This may sound even odd. But it is true.

I need a device that is capable of hardware playback of AV1 and I know there are some devices that run CoreElec that do have it

Here’s my honest question. It’s there a device that it can properly display 1920x1200?

It is a not common resolution. But where I intend to run this device is on my Workstation monitor that has this old Dell 24WFP monitor still around.

My Raspberry Pi 3B+ does display at 1920x1200 but I’m not sure about CoreElec and this is my first contact with it.

My fear is that if I buy one I will be forced to run on a 1920x1080 (Full HD) and it won’t look good.

Can anyone here help me?

Thanks

Boot CE in 1080p and make a dmesg log: coreelec:debuglogs [CoreELEC Wiki]
This will show me your EDID and I can reproduce it here local.

Or find out the EDID by your Pi log somehow. Usually it should be in dmesg log.

Like this CE log shows the EDID:

Let me see if I understood correctly.

Do you want me to provide you with a dmesg.log from my Rpi3 that is attached to my Dell monitor running at 1920x1200?

Portisch · 28 December 2022 18:11

Yes, when you have no CE device we will need at least your EDID from the display.

Kill_Bill · 28 December 2022 18:15

I have another 25" 16:10 display:

Which runs with my x96_x4 on CE ng 20 nightly 20221220 only 1920x1080,
does not show option to switch to 1920x1200.

For normal use my tv-box is connected to 4K-TV, i just connected it to the PC-screen for this test.

edit:
So on the screen, the picture is streched in height.

hbs · 28 December 2022 18:47

I understand now. I’m going to look at how to find this edid. Since on dmesg.log and kodi,log there is no mention of it

I forget to say that my Rpi3 is running LibreElec which is stripped from many things.

Maybe there is something I missed.

Here’s the output of kodi.log with verbose: http://ix.io/4jOk.

hbs · 28 December 2022 18:49

That’s exactly what I’m afraid of!

Kill_Bill · 28 December 2022 19:07

When you play a video, you can set pixel ratio in video options to 1.11, then it looks ok on 16:10 screen.
I made screenshots, but you can not see the black borders on top and bottom of pictures, just on your 16:10 sreen.

settings:

Maybe i lose some quality by doing so (vertical pixel resolution).

hbs · 28 December 2022 19:27

Is that what you’re looking for?

Portisch · 28 December 2022 20:57

Yes, this include the EDID. It looks like the Vesa mode 1920x1200 is ignored right now. It should be supported but it does not show up in list. I will need more time to take a look how to fix this.

Thanks for looking into this for me. @Portisch

As soon as you fix this I will buy a device capable of running CoreElec.

@Kill_Bill Thanks for the ratio 1.11 tip. It may come in handy someday.

Since I have your attention.

What ‘future-proof’ device would you recommend for me?

Thanks

PS: besides the resolution, the other thing I’d love to have is that the device would be capable of playing back AV1 10bit.

A SPDIF out would be great as well.

hbs · 29 December 2022 01:27

@Portisch

I received a message from a LibreElec dev telling me how to properly grab the EDID of my monitor.

I noticed that some Infos were different.

I decided to provide you with a new and hopefully log since you’re going to work on it.

Here it is: hastebin

Hope that helps.

Kill_Bill · 29 December 2022 10:07

I tried with this custom modeline in /flash/config.ini
modeline=‘1920,1200,154000,74038,59.95,1920,1968,2000,2080,1200,1203,1209,1235,1,-1,1’

But display could not handle it.
Then i tried to set this mode on 4K-TV,
and it showed a 3/4 black 4K-screen, with only about 1/4 of it in top left corner filled with 1920x1200 CE screen output.

Portisch · 29 December 2022 11:38

I did not check in detail yet but looks like the EDID does not report the vsync parameter. And the kernel do not know which VIC should be used when this is not given. Or it’s a bug somewhere… Not sure yet

freddy · 29 December 2022 20:05

Wow

Del monitor
Week 17 2008…

Still using…

Happy Testing

hbs · 29 December 2022 20:23

It is in my hands since the end of July, 08.

The specific model it’s this one: https://dl.dell.com/manuals/all-products/esuprt_electronics/esuprt_display/dell-2408wfp_user’s%20guide_en-us.pdf

It gonna make 15 years. It’s a lot of time.

The most amazing thing is that it doesn’t have a single dead pixel on it.

I think it will go for some more years of use. But if it were to fail next week I have nothing to complain about.

I have read that DELL or any other maker doesn’t do stuff to last that long anymore.

And I think it is true. Since then my sister bought a Samsung TV that only lasted 4 years. (2015-2019)

So a port of this 154MHz mode is needed.

The thing which will probably fail will be the CCFL backlight, but you can repace them.
You can also repair the PSU, by replacing components.

But this old screen uses about 75W of power, while my new one in ECO1 mode only about 15W.

This screen has integrated scaler for 16:9 on 16:10 screen (1:1), what about this option?

I think it’s not possible for us to add this resolution as we have no documentation what we need to set the hardware registers. And I did not found any info in any kernel we can check. I will try to get some help from vendors but I can’t promise much.

Can you try look at OSMC Vero 4K Kernel?

I believe they have this resolution.
