How to fixed HDMI resolution output 1920x1080p

I want make TX2 HDMI always output 1080P whatever moniter is.

suchb,

This request seems not valid if your monitor does not support 1080p…
I’ll help find if there is any setting you could use.

Thanks for your patience.

Thank you,WayneWWW
I know my issue could be illogical,but this is necessary in my case.
Looking forward to your reply.

Could you try to set below file as “monitors.xml” under ~/.config/. ?

<monitors version="1">
  <configuration>
      <clone>no</clone>
      <output name="HDMI-0">
          <vendor>ACR</vendor>
          <product>0x0440</product>
          <serial>0x52201c2a</serial>
          <width>1920</width>
          <height>1080</height>
          <rate>60</rate>
          <x>0</x>
          <y>0</y>
          <rotation>normal</rotation>
          <reflect_x>no</reflect_x>
          <reflect_y>no</reflect_y>
          <primary>yes</primary>
      </output>
  </configuration>
</monitors>

WayneWWW,

Many thanks for the solution.
Is ~/.config/monitors.xml both are functional between GUI and Framebuffer mode?

This should work only for GUI mode.

It looks not worked with monitors.xml in GUI mode.

hello,Anybody have a suggestion?

Have you directly added new xml file under ~/.config?

yes

Added monitors.xml file under ~/.config and reboot,test with a 1280x800 resolution monitor.

I want tx2 always output 1080P,but I still got 1280x800.
