Using my Android Tablet as a second screen/monitor for Linux! (Using HDMI Dummy Plug)

[@tanawatjukmongkol2178]

You don't need HDMI dummy plug for Wayland session on Linux. You can just type a command to spawn a virtual screen, with custom aspect ratio. For gnome it would be `gnome-shell --wayland --headless --virtual-monitor x` as for Hyprland it would be `hyprctl output create headless`, etc.

damn thank you so much

This didn't work maybe as I am using amd laptop.

This is one of the best videos in the recent year that showcase different ways to extend a linux screen onto an android device, imo. I can see both devices’ screens clearly in action, including different latency tests. The use case for the second android screen should not be for media/ game consumption, but if you show an additional document/ spreadsheet/ e-book or note-taking feature etc, it would be a multi-tasking beast.

sorry but youre quite wrong. 1st of all, you DONT NEED a dummy plug. thats why linux is known to be customizable. with xrandr, you can create a virtual monitor and itll still work the same way(wayland? well idk if its possible on wayland side yet this is for x11). 2nd thing, these apps use VNC. and VNC is VERY laggy for this stuff. so dont expect much. if youre gonna do a multi-monitor setup with a tablet, windows is the only way unfortunately. 3rd thing, you dont need any of these apps. you can run a VNC server from the terminal yourself, connect it from the tablet. no apps required on the host side. but again, VNC sucks. (all of the linux nerds out there, no, RDP is not an option, it sucks as just as much as VNC, lets be realistic.)

[@tanawatjukmongkol2178]

It is possible on Wayland.

@@tanawatjukmongkol2178 you cant create a virtual monitor on wayland, at least not with xrandr

Great video, never knew what a dummy HDMI adapter should have been good for. Good voice, btw.

This is a pretty good review of the latest apps that do mirroring!!! Thanks you very much.

[@hxlr666]

you can use android usb theatering to create a local network between the two devices connected with a usb type C cable

[@PU1KIT]

Congrats, man!

[@edwardfletcher7790]

It's never going to be as fast as a HDMI or USB3 🚠 cable. It's meant for passive information, reading pdf's or video conferencing....

[@tutacat]

Microsoft RD is a great low latency option, especially if you used usb networking. Gnome Remote Desktop supports RDP by default. You have to use dconf settings to change the monitorntype to 'extend' instead of 'mirror'.

[@emanoelcruz2433]

@Luke, About DeskReen and Weylus ... if you make an hotspot connection in your Laptop to simulate an "direct connection" with you tablet, should increase the performance? No?

[@YannMetalhead]

Thank you.

[@chubbychatcat7159]

how do i show my sencond screen without a dummy plug?

[@ps3301]

It is a lost cause.

[@JordanCardona]

Well I have seen what the raspberry pi can do with the Miracast but I wish that there was a program or even the script on the terminal that we could launch and then we could plug in our devices wirelessly just like Mirror cast and I know that there's already an application called genome Network display but that has a big disadvantage and that I have a TV that has Roku I tried to use Miracast with Roku but it doesn't work

[@GustavoLadeira42]

Nice video! Basically, you can't afford a second dedicated screen, you have to get used to laggy apps. 🤷 Oh, useful note: spacedesk supports USB connections now, so it's less laggy.

[@rauldragu9447]

This is neat just for the sake of casting screens to a mobile device through wifi. But I really don't get the argument of not affording a second screen. If you want to have a portable multi monitor setup then yes, a compact monitor is expensive. But if you just want a second monitor for at home, an used 1080p 60hz monitor is 20-30 bucks in my area. Just the dummy plug is around 10 bucks so it's not even cheaper for a worse experience.

[@StevenAkinyemi]

I have a steam deck that I really want to connect top my tablet. Stream Link (using the ethernet connection) isn't great for fast games and the quality isn't that great. If only we could have solution that uses USB-C. I'm almost tempted to start such project but my hands are full.

[@StevenAkinyemi]

I have an idea what might work. USB OTG and USB-to-HDMI. Essentially using the tablet as an HDMI monitor. That should work fine.

[@kdandsheela]

​@@StevenAkinyemi would it still all work natively? From my understanding there needs to be drivers involved for the PC to realize the tablet is a monitor

[@kirusnovar7083]

moonlight app?

[@Joevim]

damn pretty disappointing, had high hopes since its linux but its android that causes the problem

[@Ideasquevalelapenadifundir]

exactly, on windows it's a extremely simple process, no latency at all using usb, and on Linux it's a complete shit show

[@adithyasunil8809]

If only there was good software!

[@rauldragu9447]

Bro it's not about the software, it's about the hardware limitations of using wifi. But since the two linux apps are free and open source you can always contribute to them and maybe even implement wired support, making them "good software".

[@yrds96]

I always wonder why softwares like parsec that shares screen at 1080p over the internet with 30fps while we can't share our screen over LAN with a superior performance

[@darknodes]

Spacedesk top anyway, 1connections and done xD but sadly spacedesk dont support linux 😂
