HDMI video output works fine on some settings, for example 1440x900 and 1280x720, and xrandr shows many modes without any X11 configuration, including 1920x1080@60Hz (which it lists as the preferred mode). Full xrandr output follows:
Screen 0: minimum 8 x 8, current 1440 x 900, maximum 8192 x 8192 DVI-I-0 disconnected primary (normal left inverted right x axis y axis) DVI-I-1 disconnected (normal left inverted right x axis y axis) HDMI-0 connected 1440x900+0+0 (normal left inverted right x axis y axis) 160mm x 90mm 1920x1080 60.05 + 60.00 59.94 60.00 1440x900 59.89* 1360x768 60.02 1280x1024 60.02 1280x768 59.87 1280x720 60.00 59.94 1024x768 60.00 800x600 60.32 720x480 59.94 60.05 640x480 59.94 59.93
One thing I do not understand here: What are the columns to the right of 60.00 in the 1920x1080 line?
Anyway, the problem is if I use xrandr to switch to the 1920x1080 mode (or let X11 do so by default on startup) my television shows a black screen and an error (非対応の入力信号, "unsupported input signal"). This also happens if I use the
nvidia-settings tool to set the resolution (it also lists 1920x1080 as supported, but has the same error).
I can find this error a few places online, but nothing to with Linux, just people having problems with game consoles and older versions of the TV.
I know the TV works with 1920x1080; the manufacturer lists it and my PS3 uses 1080p just fine.
What can I do to use 1920x1080 on my TV? Is there some configuration I've overlooked?
