Resolution problem with AMD Bangho Optima 4 and HP ZR30W Display

B

bangmyhead

Hello again, since Mate worked and I can see all fine, now I am having another problem, the resolution does not go beyond 1200x800. This monitor can handle at least 3 times more that resolution, I am using a DVI adapter since the monitor its HP and only has DVI and DisplayPort but the computer its AMD and only has HDMI and DVI.

Adapters can cause problems like this.
The problem is there are many flavors of DVI. Digital, Analog ect..

On the computer end HDMI uses CEC. This is encryption scheme so you can't steal the signal.
Typically adapters interfere with this handshake. Some DVI-D adapters will passthrough.
So what you may be seeing is the resolution falling back to lowest rez because of the adapter.

This is just pure speculation on my part but just shows some of the factors involved.

Why aren't you using DVI to DVI. Are the pinouts different? That would be your best choice.

I am using DVI to DVI because I have also a DisplayPort to HDMI adapter but if I use that last option I do not see any image, does not work at all, I mean I do not even see image from computer setup with that adapter.
I only get signal from the DVI to DVI.
 
Also disappointing is the video input selection; all you get is a single DisplayPort and a single dual link DVI connection. There are no HDMI,

HP ZR30w Review

The HP ZR30w is a massive 30-inch IPS monitor with an equally massive price tag. It offers good grayscale performance and wide viewing angles but its lack of picture settings and limited video inputs hold it back.

So no HDMI on this means no CEC inside. DsiplayPort does not use it.
 
I was wrong about name of HDMI protection scheme. Not named CEC but HDCP.
Ignore that because you are not using HDMI.

You must run xrandr under Xorg for your monitor output modes.
Use a simple terminal program like xterm to pull up command prompt under Xorg.

$ xrandr
Screen 0: minimum 320 x 200, current 1280 x 800, maximum 16384 x 16384
HDMI-A-0 disconnected primary (normal left inverted right x axis y axis)
DVI-D-0 connected 1280x800+0+0 (normal left inverted right x axis y axis) 641mm x 400mm
1280x800 59.91*
DisplayPort-0 disconnected (normal left inverted right x axis y axis)
 
Nice so you can see what you have going.
DVI is running in DVI-D mode.
max 16384x16384
You can set your monitor to much higher rez.
From the above review:
The 30-bit S-IPS panel has a maximum resolution of 2,560-by-1,600 pixels

So I would start there.
 
Might have to write a small conf file for the monitor.

/usr/local/etc/X11/xorg.conf.d/screen.conf

Specifying output rez.

Code: 
Section "Screen"
  Identifier "DVI-D-0"
  SubSection "Display"
  Modes "2560x1600"
  EndSubSection
EndSection

Ok, I will try on Monday, have to left the office now. I let you know, thanks a lot
 
I took a guess on your 'Identifier' section.
It should work as it comes from xrandr.

If that don't work try these instead.
DVI
DVID
DVID0
DVI-D
DVI-D0
 
Are you sure that you have GPU drivers installed?

The fact that you can't just set it to a higher resolution and that xrandr only shows one mode sounds like software rendering is being used.

Well I just installed all I found, it's an AMD Picasso/Raven 2 [Radeon Vega Series / Radeon Mobile Series]
I don't know if I need some special driver, I have installed ATI drivers and krm.

I dunno about that but this does look odd.

maximum 16384 x 16384

That sounds pretty big and weird that it is 1:1

What I worry about is Mate is not well maintained. Is this a Mate issue?
I would try other DE's before losing much sleep..

Hmmm I could try KDE
 
When you get back to the machine try this command to see if a modesetting driver is in use:
xrandr --listproviders

To be fair, Mate gets maintained well and ericbsd keeps an eye on this DE since its the main DE for GhostBSD.

I do recommend to check GPU drivers first before trying other DE's. It would be just a waste.

If you think you have configured it correctly then you can check with dmesg | grep drm for DRM activity.

Here is an working example:

and with glxinfo | grep "OpenGL renderer" from graphics/mesa-demos or graphics/glx-utils you can check if Xorg is using your GPU. Should be the renderer llvmpipe then its software rendering.

Working example:

Code: 
glxinfo | grep "OpenGL renderer"
OpenGL renderer string: AMD Radeon RX 570 Series (POLARIS10, DRM 3.40.0, 13.1-STABLE, LLVM 13.0.1)
