Connecting Mageia Laptop to TV using HDMI ?

[vincentm77]

Hi everyone,

i tried to connect my laptop (Lenovo B5400,Mageia5) to my TV (Panasonic Viera) using a HDMI cable.

it works, I can basically mirror the screen of my laptop on the TV. However, the resolution is wrong (on the TV), and i can't find a way to get it right.

I have tried changing the reolution using the KDE "System Settings/Display and Monitor" tool but the proposed resolutions are still not ok.

Any advice ?

Thanks
Vincent

What resolution is displayed on the TV, and what should it be? Please show the output as normal user of

Code: Select all

grep -i driver /var/log/Xorg.0.log
lspcidrake -v | grep VGA
xrandr -q

[vincentm77]

Thanks Dok for trying to help.

the resolution on TV is 1920x1080, the resolution on my laptop screen is 1366x768

Note that I go from one screen (e.g. TV) to the other screen (laptop) by moving the mouse cursor to the other side of the screen...
so it looks like my desktop is divided between TV screen and laptop screen...

See here a snapshot of my desktop: on the left, the TV-screen, on the right the screen of my laptop

Looks OK for me, according to xrandr you get native resolutions on both screens, what do you want to achieve? I've got a laptop with the the same resolution on a Samsung TV and it looks exactly the same.

[vincentm77]

Thanks Lula for your answer.
I want to achieve that I see a normal desktop on the TV screen, including taskbar and all the icons I normally have on my desktop.

Right now, if I try to watch a movie (played on the laptop) on the TV screen, the video will be cut right, left, top, bottom, because te resolution doesn t seem to be correct.

[doktor5000]

That sounds strange, as the TV resolution is much bigger, so how can the movie be cropped there?

Maybe what you want is a cloned screen, so you see the same on the laptop display and TV screen.
In the window on the right (called kscreen) simply drag the laptop display on top of the TV screen, and try that way.

Another thing you can try is to define the TV as primary display or switch the laptop display off, eg. (all as user) :

Code: Select all

xrandr --output HDMI1 --mode 1920x1080 --primary --output eDP1 --mode 1366x768 --right-of HDMI1
# or
xrandr --output HDMI1 --mode 1920x1080 --primary --output eDP1 --off


xrandr --help shows all options, you can play with them and see if one setup fits your needs, don't know if the graphical UI gives you all the options

Me struggling around, getting the MSI-laptop connected to the Sony Bravia, just experienced switching cables, made all the difference.

Another thing you can try is to define the TV as primary display or switch the laptop display off, eg. (all as user) :

kscreen allows most of the xrandr actions, e.g enabling/disabling a display or changing resolutions. And positions are changed via drag&drop
Sadly there's not much "documentation" - but it's very inituitive. See also the videos at http://afiestas.org/kscreen-1-0-released/
It works pretty well on laptops where you have a key to switch display, that key will cycle through the modes.

Yes a cloned screen is exactly what I want !

In the window on the right (called kscreen) simply drag the laptop display on top of the TV screen, and try that way.

Unfortunately, that didn t help.

Please be a little more verbose.
