add support for 1440p #1181

Closed indritix closed 5 years ago

indritix commented 5 years ago

I'm trying to configure the rpi4 to work with my BenQ_EW2770QZ in native resolution (2560x1440), so far no luck. I've managed to get full HD (1080p) but can't go higher. With the 43" 4k (2160p) TV my rpi4 works though.

tvservice -s outputs: state 0xa [HDMI DMT (87) RGB full 16:9], 2560x1440 @ 60.00Hz, progressive

here's my config:

#HDMI:EDID guessing the format to be 2560x1440p @60 Hz
#HDMI:EDID found unknown detail timing format: 2560x1440p hfp:47 hs:32 hbp:81 vfp:3 vs:5 vbp:33 pixel clock:241 MHz max pixel clock is 270 MHz

hdmi_ignore_edid=0xa5000080
hdmi_cvt=2560 1440 60 3
hdmi_drive=2
hdmi_group=2
hdmi_mode=87
#hdmi_mode=82
#the pixel clock is calculated from HxVxRR, but with adding all porch/blanking pixels into H & V

Why are you ignoring the EDID? The Pi4 is now using the vc4-fkms-v3d overlay by default, so it fully parses the EDID and will allow selection of all modes listed therein.

indritix commented 5 years ago

the edid doesn't list a mode for 1440p, the highest I get is 1080p(which works when I select it)

timg236 commented 5 years ago

Please can you try removing hdmi_pixel_freq_limit=241699200 the default limit is 300000000 ? It might also be worth trying the rpi-update firmware/kernel if you have nothing important on the sd-card and are willing to try the bleeding edge code.

Do you have any other sources which output HDMI at 2560x1440 ? It's just possible that the HDMI supports only a subset of the display port resolutions. It's quite common for 4Kp60 to not be supported over HDMI1.4 inputs but admittedly I've not seen that limitation for QHD.

6by9 commented 5 years ago

The Pi4 is using the DRM/KMS stack for setting up the screen. hdmi_timings etc still have some use with legacy mode, but you then have no 3D acceleration. As @timg236 has said, there are a couple of fixes relating to HDMI setup in the latest rpi-update release, so those would be worth trying.

indritix commented 5 years ago

I'll try once back home with the default limit. I already did a rpi-update yesterday, no luck.. sorry that's the only 1440p I have at the moment as a side note, my dell xps 9370 with arch linux over DP and lenovo X1 Yoga 2Gen over HDMI work fine with the mentioned monitor in native 1440p

indritix commented 5 years ago

  • In X run the Screen Configuration application

  • Right click on the rectangle labelled HDMI-1.

I don't see a Screen Config App, is there a cmd for that?

6by9 commented 5 years ago

attach the resulting file here.

The parsed thing is next to useless. With the raw file I can emulate your setup on my Pi4.

Raspbian Buster has "Screen Configuration" under the Preferences menu. Otherwise it is arandr.

indritix commented 5 years ago

oops sorry 'bout that, here's the file. edid.zip I don't have "Screen Configuration" under the Preferences menu, tried with randr but couldn't really select anything other than 1080p

6by9 commented 5 years ago

I don't have "Screen Configuration" under the Preferences menu, tried with randr but couldn't really select anything other than 1080p

That comes back to my first step of using a vanilla Raspbian Buster download. Please confirm that you are doing that with no changes to config.txt.

The quickest way to provide all the info to try and debug this is to run the raspinfo script from https://raw.githubusercontent.com/raspberrypi/utils/master/raspinfo/raspinfo and post that.

6by9 commented 5 years ago

Using your EDID file on my Pi4, I get the following as my list of supported modes:

pi@raspberrypi:~ $ DISPLAY=:0 xrandr

   720x400       70.08

Using "Screen Configuration" (arandr) to set up the screen I get all those modes listed in the drop down menu, and my monitor seems quite happy with 1440x900@59.9 and 74.98Hz.

There have been some updates in the recent days to the firmware to address some HDMI clocking issues. Normal warnings over rpi-update apply, but it'd be worth updating to see if they are the cause of your issues.

by 1440p I mean 2560x1440@60

You should be able to manually add modes via xrandr in the same way as any other Linux machine, eg https://ubuntuforums.org/showthread.php?t=1112186, but it's throwing errors at present.

hdmi_timings currently doesn't play well with KMS. I will look at whether it can be improved, but I'm afraid that displays with dodgy EDIDs are currently a pain. NB That this will be fixed in the Linux kernel, not in the firmware. Sorry, but I'm not messing with the firmware EDID parser unless I really have to.

Thanks for the raspinfo dump - at least I now know what your system is doing.

actually my edidparser shows that my monitor advertises itself correctly, the problem is it's resolution seems not to be supported :( HDMI:EDID found monitor name descriptor tag 0xfc HDMI:EDID monitor name is BenQ_EW2770QZ HDMI:EDID failed to find a matching detail format for 2560x1440p hfp:47 hs:32 hbp:81 vfp:3 vs:5 vbp:33 pixel clock:241 MHz HDMI:EDID calculated refresh rate is 60 Hz HDMI:EDID guessing the format to be 2560x1440p @60 Hz HDMI:EDID found unknown detail timing format: 2560x1440p hfp:47 hs:32 hbp:81 vfp:3 vs:5 vbp:33 pixel clock:241 MHz HDMI:EDID established timing I/II bytes are A5 6B 80

In which case that isn't the EDID file that you attached.

Actually I'm noticing from my parser

Sounds like a Samsung Syncmaster to me, not a BenQ.

Looks more plausible.

So that parses reasonably, and xrandr reports a sensible list of resolutions, including 2560x1440@59.95

My 4k monitor doesn't support 2560x1440 though, so I can't check if the Pi is actually producing a sensible output for that mode. I'll have to try and hunt down an alternate monitor.

6by9 commented 5 years ago

Monitor supporting 2560x1440 @ 59.95 found, and it works fine.

Sorry, there's not much more that we can do here. There are some cables that are marginal and will fail at higher frequencies, but if the same cable is doing 4k to your TV then that sounds unlikely.

that looks like you aren't using the FKMS driver, although your dmesg appears to say it is loaded.

As Gordon says, please try with a fresh install - something looks very screwy with your current one.

but when I select 1440p in "Screen Configuration" (this time it shows up), no changes are made after I click apply (I can see it tries, but unfortunately no luck), and the resolution reverts back to 1080p. Maybe this time my edid.dat will help. edid.zip PS: yes I already did a rpi-update

tried with latest firmware, still impossible to go higher than 1080p. Why I can select the 1440p resolution in "screen configuration" (or alternatively with xrandr on a terminal) but then after clicking apply the changes don't apply and the resolution reverts to 1080p is still a mystery to me. if you need logs/traces just let me know..

Ok, I managed to solve the problem with xrandr (thanks to the archlinux wiki), would be nice if there was a way to translate xrandr parameters into config.txt entries though.

@indritix Could you please post your solution? I am facing a similar issue. xrandr isn't able to set the resolution either.

@indritix @sooriravindra

Hello, I've recently tried attaching my Raspi 4b to this same monitor and cannot get it to work with 1440p. I can select 1080p from the drop down menu in preferences and it works fine, but if I try 1440p it goes to a black screen and is stuck there.

Can someone share their solution?

Thanks.

now do it for dual screen.

it's absolutely a face plant before the finish line with the pi4 not supporting this resolution. It is one of the most common resolutions in displays right now. What a tragedy. This Pi is pretty much worthless to me now because it doesnt support one of the most common resolutions, and yet touts itself as supporting dual 4k.

what a joke.

hdmi_mode:1=87
hdmi_cvt:1=2560 1440 60 3 0 0 1
hdmi_pixel_freq_limit:1=400000000

as in the docs https://www.raspberrypi.org/documentation/configuration/config-txt/video.md section "HDMI mode options / Note for Raspberry Pi4B users".

You're obviously using a Pi4 if you're wanting dual screens, therefore the FKMS driver is active by default. X will select the highest mode automatically as it reparses the EDID and selects a mode of its choosing. If using the console only, then as an alternative to the above you can add disable_fw_kms_setup=1 to config.txt, and again the kernel will reparse the EDID for choosing a default frame buffer mode. If you've disabled FKMS, then you can hardly complain that it doesn't work out of the box.

Interesting that we had the same issue on the forum in the last day or so. Is that you too and you felt like a further complain? https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=273548

Is it? I've never come across a monitor of that resolution.

It's not in the standard list of 4K resolutions either. Wikipedia has a list https://en.wikipedia.org/wiki/4K_resolution, all of which I believe we support.

most 27"-31" displays are this resolution. If you've bought a monitor in the last 10 years, you've probably seen it ;)

You've disabled the line dtoverlay=vc4-fks-v3d, and have overscan enabled. The overlay is enabled by default, so what is your reasoning for disabling it? Start again with a clean Raspbian install and X will select 2560x1440 on both monitors.

niether of you have attempted to help at all. You have accused me of creating duplicate accounts so that I can complain under two names??? is that something you've done?

if you had looked closer, I think it would have been pretty obvious that was not the case, but you just jumped to conclusions it was because the same topic came up twice in two weeks? seriously? delusional, much?

you then went on to accuse me of making changes to things that I have not. you didn't ask me if I made those changes, you accused me.

you saying that you've never seen a monitor with this resolution is ignorance on your part. I'm guessing that's why you're so angry, it made you feel stupid, and you're attempting to play the "you're rude" card.

you really weren't helping anyways. so no real loss there. all you said was that you never came across a monitor with that resolution, and for that I think you've been living under a rock. do you actually think that was going to be helpful? telling me you never saw a monitor with this resolution. what was I supposed to do with that info? throw it away? pretend it has a different resolution? add/remove pixels myself?

funny way of helping.

illmillrig commented 4 years ago

you can't buy a brand new pi4, and a brand new 27" display, and use them together natively.
