Re: STICKY: Setting up HDMI output when video output is wrong.

Mon Aug 05, 2019 10:08 pm

I'm trying to get my pi4 to output in standard def resolution and I'm only seeing 1920x1080 on my monitor. My goal is to out put video for my Sega Blast City monitor and when I try to hook it up to the monitor, the image is split 3 ways and compressed. I was told it is probably due to the output still being in HD instead of SD. I've tried to modify the config.txt file for standard def. I've tried all sorts of settings and nothing seems to work. Has anyone else successfully connected their Pi to an actual arcade monitor? If so, what settings did you use? Was it a pi 4 or 3 and below?

Image

The image looks fine on my standard PC LCD 23" monitor. Only when it's hooked up to the cab, it's all skewed.

Here are the settings I had to use on a Vizio D32hn-D0 to get a display from my RasPi 4"
hdmi_ignore_edid=0xa5000080
hdmi_group=1
hdmi_mode=16

And while all of this re-configuring of these videos parameters is way over the head of most newbies, they'll sure learn a lot by sticking with it and getting their monitor working with there RasPi 4!

Hi,

Got this 4K display here: the LG 27UK850-W

Added

Code: Select all

hdmi_enable_4kp60=1
to the Pi4's config.txt

But the highest resolution I get is 2560x1440 at 59.95Hz frequency

the display should be able to handle 3840x2160 at 60Hz ...

after trying to switch HDMI-1's resolution to 3840x2160, the screen goes dark and shows a "no-signal" message. Then after 10 seconds, the pi switches back to 2560x1440.

Hi all!
I am tgrying to get my Sony TV working with my Rasp Pi4 4GB together with the new RaspEX Build 190807. I allways get an Unsupported Signal Messsage on my TV.

I use this config.txt:

Code: Select all


# For more options and information see
# http://rpf.io/configtxt
# Some settings may impact device functionality. See link above for details

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
#disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=1

[all]
dtoverlay=vc4-fkms-v3d

But i am confused about the output of some commands. I get this after boot:

Code: Select all

And if i use the following command i get this - and also no output:

What is "RaspEX Build 190807"?
What does tvservice -m CEA report?
If "RaspEX Build 190807"" is not (equivalent to) current Raspbian Buster try that instead and report back. Also, for Buster, and since my TV possibly has similar capabilities to yours you may find these recent notes of interest: http://www.cpmspectrepi.uk/raspberry_pi ... erP4B.html - in particular your config.txt seems to have had least one inappropriate entry (in the [all] section).
Trev.
Still running Raspbian Jessie on some older Pi's (an A, B1, B2, B+, P2B, 3xP0, P0W) but Stretch on my 2xP3A+, P3B+, P3B, B+, A+ and a B2. See: https://www.cpmspectrepi.uk/raspberry_pi/raspiidx.htm

I'm trying to configure the rpi4 to work with a BenQ_EW2770QZ monitor in native resolution (2560x1440), so far no luck.
has anyone managed to get 1440p on a 27" monitor?
I have already tried here https://github.com/raspberrypi/firmware/issues/1181 for help.
Edit: solved with xrandr (arch wiki)
Please post your solution.

Hi all,

My HDMI monitor falls off in this category HDMI group= 1 and HDMI mode = 16. I tested it with the command given above but still, it doesn't give output on the HDMI monitor. I have checked my HDMI monitor conf and it is 1080p/1920x1080 Hz. When I changed in config.txt it stopped ssh also. Please help...

Re: STICKY: Setting up HDMI output when video output is wrong.

Yesterday I got an Asus VT168 monitor (with touch).

The monitor has two inputs: HDMI and VGA.

Through HDMI (both Pi 4 ports) it is not recognized by the Pi 4, even though the Pi 3 (with the same SD card) has no problems with connecting it straight HDMI to HDMI.

I then tried the VGA port (using a VGA - HDMI cable): that works well, even with the recommended somewhat strange resolution of 1366x768 @59.79Hz.

I use Buster (10). Any help appreciated on how to get it also working using HDMI.

Note: the touch part does work out of the box at both the Pi 3 and Pi 4 so while I would really like to only use HDMI - HDMI it is a great working solution in the end having a touch screen on the Pi for a little over 100€.

Update:
I now also got HDMI output by enabling:
hdmi_safe=1
hdmi_force_hotplug=1
config_hdmi_boost=4

It does not work with 1366x768 yet but does with 1024x768.

Update 2:
I ended up using 1920x1080p, seems to work ok. Everything is a little small but at least touch and the screen are in synch and it properly fills my entire screen etc through HDMI. I could always fall back to VGA of course. (This post helped me understand setting display modes better: https://www.raspberrypi.org/forums/view ... p?t=249045)

Update 3:
Because of some other software I updated Raspbian. Now it does accept 1366x768 but it does now have an 'underscan' issue.

Is (re)solved it, now it works perfectly!!!

Disabled hdmi_safe again (was solved in the update apparently):
#hdmi_safe=1

disable_overscan=0

Fiddled around with overscan_ borders:
overscan_left=15
overscan_right=10
overscan_top=8
overscan_bottom=5

framebuffer_width=1366
framebuffer_height=768

hdmi_force_hotplug=1
hdmi_force_mode=1

hdmi_group=2
hdmi_mode=81

hdmi_drive=1
config_hdmi_boost=2
