I wonder if you're getting a 2560x1600 desktop scaled down to 1920x1080. You should be able to tell for sure by looking at the output of "xrandr --verbose" and "nvidia-settings -q CurrentMetaMode" after setting that configuration. I think Adam's analysis is right: your GPU and/or cable can't support the full 3840x21600 native mode of this display, so it falls back to the highest mode the monitor says it can support that fits within the available bandwidth. -- Aaron I use the HDMI cable.

> Here is the log: https://people.freebsd.org/~yuri/Xorg.0.log So from here you can see: DFP-0: 330.0 MHz maximum pixel clock Samsung U28D590 (DFP-1): 230.0 MHz maximum pixel clock EDID maximum pixel clock : 300.0 MHz Validating Mode "3840x2160_30": Mode is rejected: PixelClock (297.0 MHz) too high for Display Device (Max: 230.0 MHz). This means that 3840x2160 @ 30 Hz requires a pixel clock of 297 MHz, your monitor can go up to 300 MHz, but your video card can only support 230 MHz on that output. Since there isn't enough bandwidth between the video card and the monitor, this one is removed from the list of available modes. > > If that doesn't work, what monitor, video card, and cable type are > > you using?

The output says that although DFP-1 is limited to 230 MHz, DFP-0 supports 330 MHz so if you have a different output on the card you could try that in case only one output supports 4K.

I know that 2560x1600 is supported because the NVidia settings program can switch to 2560x1600 by typing 2560x1600 into it. The window manager stays in a square with the size 1920x1080, and the extra space appears around it. But how to change xorg.conf in order to make 2560x1600 a default resolution? I tried to add the line Modes into this section: SubSection "Display" Viewport 0 0 Depth 1 Modes "2560x1600" "1920x1080" EndSubSection But Xorg fails to accept the 2560x1600 value with this warning: [ 9995.669] (WW) NVIDIA(0): No valid modes for "DFP-1:2560x1600"; removing. and still uses 1920x1080. I would run xrandr after X has started (even at the incorrect resolution) and grep for 2560 - it should give you the specific resolution that Xorg detects as valid. For example on my system: $ xrandr |grep 2560 HDMI-A-0 connected primary 2560x1440+1080+0 (normal left inverted right x axis y axis) 553mm x 311mm 2560x1440 59.95*+ $ in my environment i do not populate xorg.conf with resolutions, rather I let X auto-detect them. Then if the default resolution does not do what I want I have a script which sets the desired layout and resolution. For example here's one for my dual monitor setup: $ cat ~/.screenlayout/duce.sh #!/bin/sh xrandr --output DisplayPort-0 --mode 1920x1080 --pos 0x0 --rotate right --output HDMI-A-0 --primary --mode 2560x1440 --pos 1080x0 --rotate normal --output DVI-D-0 --off $ Regarding the nvidia utility setting the 2560x1600 resolution - perhaps its injecting custom modelines, if that is the case you can also do this via xrandr using the --newmode argument. cheers, -pete -- Pete Wright p...@nomadlogic.org @nomadlogicLA ___ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: https://lists.x.org/mailman/listinfo/xorg Your subscription address: %(user_address)s
