[SOLVED] After boot, visible screen is reduced to quarter of the native resolution

[p0sti]

Some days ago my raspberry suddenly switched its display mode. It is now showing only a quarter of the available native resolution (1080p) of my TV. Tried several different options in the /boot/config.txt, none of them working. I guess it's worth noting that I've been using a different HDMI cable since a few weeks. This was however working fine for a certain amount of days and then the problem suddenly appeared. Switching to an alternative HDMI cable didn't make a difference, so I'm not certain if that's really the source of the problem.

Software
XBian version: v1.0B2
XBMC version: 12.2 (Frodo)
Overclock settings: Default

Hardware
Power supply rating: Link
RPi model (model A/B 256mb/512mb): model B
SD card size and make/type: Transcend 16 GB
Network (wireless or LAN): LAN
Connected devices (TV, USB, network storage, etc.): TV (Sony Bravia KDL 46EX500), USB hub with wireless mouse/keyboard and two external 2 TB USB drives.

Logile
Link to logfile(s): Nothing yet.

Problem description:
See above.

How to reproduce:
None. Suddenly appeared.


These are the current settings in my /boot/config.txt
Already tried some other hdmi_modes as well, without success.

Code:

#initramfs initramfs.gz  0x00a00000
gpu_mem_512=256
gpu_mem_256=128
initial_turbo=1
disable_splash=1
arm_freq=840
core_freq=275
sdram_freq=400
over_voltage=0

#hdmi_safe=1
config_hdmi_boost=4
hdmi_group=1
hdmi_mode=16
hdmi_force_hotplug=1
hdmi_ignore_cec_init=1
disable_overscan=1
hdmi_ignore_edid=0xa5000080

Just in case it is relevant:

Terminal

xbian@xbian ~ $ tvservice -s
state 0x12001a [HDMI CEA (16) RGB lim 16:9], 1920x1080 @ 60Hz, progressive

Terminal

Group CEA has 59 modes:
mode 1: 640x480 @ 60Hz 4:3, clock:25MHz progressive
mode 2: 720x480 @ 60Hz 4:3, clock:27MHz progressive
mode 3: 720x480 @ 60Hz 16:9, clock:27MHz progressive
mode 4: 1280x720 @ 60Hz 16:9, clock:74MHz progressive
mode 5: 1920x1080 @ 60Hz 16:9, clock:74MHz interlaced
mode 6: 720x480 @ 60Hz 4:3, clock:27MHz x2 interlaced
mode 7: 720x480 @ 60Hz 16:9, clock:27MHz x2 interlaced
mode 8: 720x240 @ 60Hz 4:3, clock:27MHz x2 progressive
mode 9: 720x240 @ 60Hz 16:9, clock:27MHz x2 progressive
mode 10: 720x480 @ 60Hz 4:3, clock:54MHz x4 interlaced
mode 11: 720x480 @ 60Hz 16:9, clock:54MHz x4 interlaced
mode 12: 720x240 @ 60Hz 4:3, clock:54MHz x4 progressive
mode 13: 720x240 @ 60Hz 16:9, clock:54MHz x4 progressive
mode 14: 720x480 @ 60Hz 4:3, clock:54MHz x2 progressive
mode 15: 720x480 @ 60Hz 16:9, clock:54MHz x2 progressive
(prefer) mode 16: 1920x1080 @ 60Hz 16:9, clock:148MHz progressive
mode 17: 720x576 @ 50Hz 4:3, clock:27MHz progressive
...

Attached also a photo that shows the problem on my TV.

Anything else I might try before flashing the system?

This a common and simple occurrence. Just press the #key on a UK keyboard. The one next to the return key and you will be back in full screen mode.

Maybe it sounds stupid but what happens when you hit the "\" or "|" key (or shift "\" or shift "|" )?
In my case these keys are close to my return key and sometimes I hit these keys I get the same result as your screenshot.

D'oh! That solved it! You were right, that key is right beside the return key on my air mouse. Must have hit it accidentally. Thanks a lot!
