You can also set the display area and other parameters by modifying the
config.txt
file,
either manually or via Telnet (see Setting Configuration Parameters on page 49). For
example, the
Video/Audio Output Setting
section lets you modify saturation, contrast,
hue, brightness, and aspect ratio.

Adjusting the Display Area of Output Devices (VEMS 5.x)
VEMS 5.4 or higher. If necessary, you can fine tune the channel guide graphics display area
for output devices (i.e. monitors) connected to each set top box in your network. You can
shrink the display area of the output by up to 20 per cent to match the unique specifications
of each monitor. This does not affect the full screen size of the video—it only affects the
channel listing and VEMS page display.
Portal Server Mode
You can adjust the display area of output devices by modifying the
adjust.xml
file in VEMS.
This file is located in the following folder on the VEMS Portal Server:
C:\Program Files\VBrick\MCS\VEMSPisces\adjust.xml

Note At STB startup, HDMI output format is based on the EDID signalling between the
TV and the STB. If the TV does not report that it supports 1080P, the STB will fall
back to a lower resolution. In some cases you may wish to force 1080P regardless of
the EDID signalling. This will support TVs that play 1080P but do not perform EDID
signalling correctly. To force output to 1080p, set the following parameter in
/root/
data/config.txt: stb.hdmi.validate_edid_format: 0
(This parameter is in the
"Video/Audio Output Setting" section. See Config.txt File on page 50.)
