Laptop and external (TV) screen

English Hardware
1

I need to do a presentation and duplicate my screen on a 70" TV screen. I have a Dell Inspiron 5555 (15" 1366 x 768) with an HDMI output.

When I connect the HDMI and the external screen it connects, but the problem is that Leap extends the external TV screen to the right.

I’d like Leap to mirror the laptop screen to the external TV screen. How can I do that?

I’ve checked settings > configure > hardware > display. I see both screen: epd and hdmi and they are side by side but I don’t see a setting for mirroring the screen (or I’m looking in the wrong spot.)

Thanks

Which desktop are you using?

I vaguely recall with KDE one would go to : settings > configure desktop > display and monitor

(or something like that) .

LXDE, Gnome, XFCE would likely have a different track to an appropriate control.

KDE

I did go there: settings > configure > hardware > display and I don’t see anything for mirroring

Thanks

Its been a couple of years since I last needed to do this with my laptop. Currently, I have no means of testing such, in the new location (retired) where I live.

Do you get a screen like this:

if so - is there anything under ‘orientation’ specific to your second display?

Grap the “virtual” display of HDMI with your mouse and drag it over the “virtual” display of your Laptop.

If prior suggestions fail to provide a solution, please install inxi (if not already installed) and from Konsole provide output from the following:

inxi -Gxxaz
xrandr | egrep 'onnect|creen|\*' | grep -v disconn | sort -r

Hello,

The way I do it is : windows + P button, (just like on Windows), and it pops up a screen where I can set: only first screen, only second screen, mirror, extend left and extend right.

I’m using TW, KDE interface on an Acer aspire laptop.

Hope it works.

No, mine is different: https://i.imgur.com/e8wK7AL.png

but I have it working if:

  1. Boot w/o connecting to the external HDMI connected
  2. log in
  3. set the TV on and ready to input of the HDMI

Then the TV mirrors and here’s the screen I get from the hardware > display monitor (just above)

Thanks

Doesn’t work.

Windows-P works but differently. I just get a quick popup saying: “Changing Screen Layout” but, if I do it multiple times, eventually, it gets there. It looks like it’s cycling through the various options, which is good enough for me :slight_smile:

Thanks
