Cant select 1920 by 1080

[curious_pi]

Hi I am using model B+

Code: Select all

$ uname -a
Linux raspberrypi 3.12.35+ #730 PREEMPT Fri Dec 19 18:31:24 GMT 2014 armv6l GNU/Linux

My monitor has a VGA and a DVI port so I am using a HDMI to DVI cable.

Problem is the Pi is selecting 1776 by 952 and there is no option to select any other resolution.

I tried adding hdmi_mode=82
but no change in resolution

Please help me out.

Can you post the output of tvservice -m DMT?

Post the output from a tvservice -m CEA && tvservice -m DMT command.

Now display is fullscreen but the resolution is 1872 by 1048 (show in Display settings).

Post your complete config.txt.

[DougieLawson]

It should run in mode 31. So what do you have that's stopping it? Try adding

Code: Select all

hdmi_group=1
hdmi_mode=31

to /boot/config.txt and removing any other settings with "hdmi" in them.

Done. Feels the same. What is the command which prints the present screen resolution ?

[rpdom]

tvservice -s shows the current video output mode.

and fbset will show you the available framebuffer size (minus the overscan settings)

Have you updated the right config.txt?

If using NOBS use the recovery system config editor.

I guess the correct resolution is selected. Thanks everyone.
