Need some help with proper Full HD output on a TV

Post by Ovidiu »

Hi there,

I'm still using the last free version of wtware and am trying to connect my RPi 3b+ to my TV and connect to my virtual WIN 10 machine via RDP.
At first I had the problem that part of the display was basically show outside of the TV, i.e. I could press the WIN button to access the menu but I couldn't see the WIN button as it was "outside" the TV. I fixed that by un-commenting this line in my config: disable_overscan=0

The problem I am struggling with right now is to get the full HD resolution. Here is my condensed config (I removed all commented lines for easier reading).

With this config, connecting to my 4k TV and checking my resolution via http://whatismyscreenresolution.net/ I get: 1459x787

In my opinion this is the relevant config part:

Code: Select all

hdmi_drive=2
hdmi_group=1
hdmi_mode=16
Full config file:

Code: Select all

# Uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan.
disable_overscan=0

# Force the monitor to HDMI mode so that sound will be sent over HDMI cable.
hdmi_drive=2

disable_splash=1

# Uncomment for 16-bit color. It is up to two
# times faster than default 32-bit.
#framebuffer_depth=16
framebuffer_depth=32

# Enable onboard audio (HDMI or jack).
dtparam=audio=on

# Enable improved audio driver
# https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=136445
audio_pwm_mode=2

# hdmi_group options
#0	Auto-detect from EDID
#1	CEA (Consumer Electronics Association, the standard typically used by TVs)
#2	DMT (Display Monitor Timings, the standard typically used by monitors)

# use for TV
hdmi_group=1
hdmi_mode=16

#hdmi_group=1 hdmi_mode alternatives
#16	1080p	60Hz
#34	1080p	30Hz

# use for Monitor
#hdmi_group=2
#hdmi_mode=69

#hdmi_group=2 hdmi_mode alternatives
#69 = 1920x1200
#82 = 1920x1080 

Can someone spot the problem or share a working config file for full HD please?

###edit###
I forgot to mention that I boot from SD card and everything is saved on the card, no network boot, no DHCP options are set. I simply want to be able to do some light office work on my TV without having to go fetch my laptop :-)

###edit2###
In case it matters, here is my config.wtc file on the SD card inside the configs folder:

Code: Select all

server=local.network.win10.server
keyboard=de
display=1920x1200, HDMI
ntp=pool.ntp.org
scale_factor=125
disk=usb
printer=usb
timezone=W. Europe Standard Time
sound=on
sound_rate=44100

"display=" option in wtware config on Rapsberry does nothing. It's ignored. WTware uses mode that is set by Raspberry firmware.

Raspberry firmware set video mode.

config.txt is a configuration file for Raspberry firmware. Solution is here. And it's not related to WTware. Official manual about config.txt is here: https://www.raspberrypi.org/documentati ... /README.md Google knows many user cases.

Thanks. I have removed the unnecessary display= setting from config.wtc

I have read the link you posted: https://www.raspberrypi.org/documentati ... /README.md after reading that link I have come up with this config:

Code: Select all

framebuffer_depth=32
hdmi_drive=2
hdmi_group=1
hdmi_mode=16
Should that not give me 1080p on my TV? Am I overlooking something?

The only other info I am finding on the link you posted is this:
What modes does my device support?
You can use the tvservice application on the command line to determine which modes are supported by your device, along with other useful data:

tvservice -s displays the current HDMI status, including mode and resolution
tvservice -m CVT lists all supported CVT modes
tvservice -m DMT lists all supported DMT modes
Is the tvservice command supported on the wtware terminal console?

Never try to connect to TV. And there is no tvservice command in wtware.
