First of all great app! it's incredibly fast and low latency. 🔥
Maybe I'm missing something, but currently if I want to change what is shared in a connection, I tihkn I have to first disconnect it, then share link again because the old session is broken.
Would be very nice to be able to either:

I have a PC that is connected to the router via cable, and the router is giving away WI-FI. Should this tool work in that case and connect my smartphone, which is connected to wifi, to PC?
I saw on the readme that you are looking for a way to get rid of the dummy plug. Well, if you're running any linux distro with Xorg X11 display server, then you can simply:
remoteHScreen=2560
remoteVScreen=1600
refreshRate=60
existingScreenName="DP1"
params=$(gtf ${remoteHScreen} ${remoteVScreen} ${refreshRate} | grep Modeline | sed 's/^\s\sModeline \".*\"\s*//g')
xrandr --newmode "extraScreen" ${params}
xrandr --addmode VIRTUAL1 extraScreen
xrandr --output VIRTUAL1 --left-of ${existingScreenName} --mode extraScreenAnd to delete the screen:
xrandr --output VIRTUAL1 --off
xrandr --delmode VIRTUAL1
xrandr --rmmode extraScreenI believe this can be done on Wayland as well, but since I don't use wayland, I dont' really know...
Regarding the other 2 OSes:
How to run this awesome apps without electron? just from browser (chrome) only?
Right now there doesn't seem to be system tray support, at least not under Linux. It would be really cool if Deskreen could be minimized to the tray.
Does it support android or ios?
Could you recommend some Display Dummy Plugs? I do not know exactly which kind of device deskreen needs, for example is this one good?
A list with examples and referral links would be good for the project
Is it possible to share touch inputs? since i mostly share screen to my phone it would be awesome if i could control from there too.
master branchDEBUG_PROD=true yarn build && yarn startSelect windows or screen
I can't select it, i click on it but nothing happens :(
All OS' have the option to have multiple "Desktops", it would be very useful to be able to share an application thats on a Desktop your not currently on. (for example on windows you can press the windows key + TAB to open more desktops and windows key + ctrl + arrow keys to change between desktops)
On AppImage version.
It fails to recognize local network devices.
The app itself works ok, and clients reach it without problems. But the "Not WiFi and LAN Connection" dialog is stuck and preventing to allow an incoming connection.
This dialog should be easy to skip or override.

Device: iPad 2 (iOS 9.2.1), iPad 1 (iOS 5.1.1)
Browser: Safari
When accessing the client URL (http://xx.xx.xx.xx:3131/123456) it shows a blank page and can't connect.
Not sure if this is a quick fix or a major overhaul of the code, they're pretty old so don't feel too bad about it 😊
It would be so nice to use Deskreen in these bricks and bring them back to life!
Great work BTW
Alow button is usually associated with blue / green color, so i think you should change the color of the Allow button.
Hi
I tried to scan the QR code with the implemented scanner of Firefox on Android. It wasn't recognized in dark theme, light theme was fine.
(I am using the Linux version of Deskreen.)
Both screens should be offered to share.
Only the bigger primary screen is offered to be shared.
In the Select step, only the primary screen is offered to share
I wanted to use an iPad as secondary screen. The secondary screen is cable connected and shows up in display settings of Windows. Windows is set to extend the Desktop to the secondary screen.
Windows 10 20H2

Primary screen 5120 x 1440
Secondary screen 2048 x 1536
Creating a virtual display with xrandr that can be broadcasted as an extra monitor is fairly easy on Linux. I think that this method should be implemented as a guide as it is a viable method for Linux users without the need of extra drivers or a dummy plug. To achieve this I did the following:
First, run the following command:

Here I selected one of the disconnected outputs. For this example I am going to use DVI-D-0
If there is no output mode, one can be added with
xrandr --addmode DVI-D-0 1920x1080
# you may use the output you selected and the resolution you wantNext step is to identify the display you are going to use to position your new display. For example, I want to place my virtual display to the left of my primary display, which is HDMI-A-0, so I run the following command:
xrandr --output DVI-D-0 --mode 1920x1080 --left-of HDMI-A-0
# replace DVI-D-0 with the virtual output you selected
# and 1920x1080 with the resolution you chose on the previous command
# other options are --right-of, --above and --belowFinally, when running deskreen:
The virtual display is available (Screen 2).
If you want to disconnect the display, just run:
xrandr --output DVI-D-0 --off
I am willing to do a complete guide and open a pull request if you think it is a good enough method.
I'm using Arch Linux with Wayland (swaywm) on Thinkpad X1C gen7.
When I share a window to my Android phone (Sony XZ2c) Brave browser, it works well.. As long as the window is being rendered on the laptop.
When the window shared is not being rendered on the visible workspace on the source machine, the updates are very laggy. For example, if I try playing a video on my laptop and share it to my phone and navigate away from the workspace hosting the video on the laptop, the video sharing is only sending a frame every second or so.
Can we add a BR Portuguese translation? I could work on it!
As you mentioned on the website, you said you'd like Raspberry Pi support. I just used the compiling instructions to run deskreen on my Raspberry Pi, and it ran without a hitch. I was testing on my pi's browser window, but it did properly capture and display my pi's screen. I think if you directly built this for armv7l, then it would work perfectly.
Regarding a display driver for macOS, this may be a starting point: https://github.com/icedman/EWProxyFramebuffer
Some details can be found at https://www.tonymacx86.com/threads/share-virtual-display-like-sidecar-on-mojave.285494/
Originally wrote it on HN, but this seems a better place to start discussion.
Android 10 introduces "Desktop mode", vendors like Samsung, LG or Huawei offers own solutions for additional separate screens. There are also commercial solutions for virtual screens on Android from company offering DisplayLink chips (they claim it is easy to modify android to support additional screens). Getting such a driver to mainline Android will be probably difficult, but there is an option to provide it for example for LineageOS or for rooted phones.
About page doesn't have the source code link for the project. please add it
I have ethernet and wifi (sometimes both connected) on the MacOS - allow to choose which Adapter (actually its IP address) is written in program and in QR code.
Give a common ip address for all remote devices to visit and let the user select id, instead of entering it as part of url this way reconnection will be effortless even if server has created a new id.
Would be great if we could use our Android/iPads as external screens via deskreen.
Actually, there isn't a Windows portable version, yet.
Please, add a portable version: I'd like to test the app features but without installing it.
The list seems to show only some of all active applications windows - like 12 or 16 (can't check right now). When I add a new browser window for instance, it does not show up .. even after reload button press.
Make it work even if the screen is closed
Host: Win 10
Sharing 1 specific app window to another desktop on the local network
Issue: After about 10 minutes the app window on the client disconnects
Note: When sharing the entire desktop (same host/client) no disconnect occurs
Thanks again!!

Add Deskreen to Flathub.
Firstly great work on this app - and thanks for open sourcing it!!!!!!!!
It seems that in the share App Window option (Win 10 host) that there is either
I am attempting to share a specific app window but it is not available in the list

Under MacOS using multiple Desktop - sharing Application Window on Desktop 1 - say Chrome. Switching to Desktop 2 - sharing pauses ... can it be made to continue?
Only one device can be connected, an error will be reported when the second device is connected.
You were not allowed to connect.
You may close this browser window then try to connect again.
I am trying to open Deskreen url in an Android Webview.
But I got this message :
I/chromium: [INFO:CONSOLE(2)] "TypeError: Object.values is not a function", source: http://192.168.199.137:3131/static/js/2.5f2b9264.chunk.js (2)
BTW: It's working well with chrome on Android.
Would you please give me some advice to make it work with Android Webview?
master branchDEBUG_PROD=true yarn build && yarn startI expect the connection stays even when the tablet's screen is off for a while.
The tablet's screen goes off automatically after 2 minutes to save battery.
If the tablet's screen stays off for a while (>5 minutes) when I turned the tablet screen on again it returns:
Deskreen Error Dialog
Something wrong happened :(
Closing the browser and opening it again did not work.
On Deskreen "Connected Devices" windows shows none devices connected.
If I get the tablet on again in a short period (<5 minutes) it resumes the connection, and updates the remote screen properly.
The connection is lost after the tablet's screen get off for a while (more than 5 minutes or so)
Connect a tablet in Deskreen
Let it turn off automatically and let if off for more than 5 minutes or so.
Turn the tablet on again and you see there is no active connection to deskreen anymore.
I am using an Android Tablet Lenovo TB-8703X running Android 8.1.0 as a connected device and google chrome as primary browser.

Awesome app!
It would be great if a cli only version is available, it would be easier to programmatically start the sharing
Share screen and sound with the connected device.
Intended use case(s):
Hello. Due to various reasons, I cannot connect my phone and my PC to the same wifi. By using services such as ngrok, I hoped I would be able to connect, and use the app. However, it gave a "something went wrong" message. Please add support for these services. Thank you!
Hi,
I found a virtual monitor driver on this site
https://www.amyuni.com/forum/viewtopic.php?t=3030
Initial testing on Windows 10 64bit shows it works for me.
Could we use this driver for Windows 10?
Some computer screens allows to flip them by 90 degrees. Would be nice to have option to flip image (and set virtual screen resolution accordingly)
Perfromance is great, but cpu usage is too high.
Hello. I really love this project, but it is based on an electron boilerplate which used the MIT License, and you can't change the MIT License. So I would switch to it (due to legal reasons).
(e.g. 21fa81a)
Great tool. Would love to be able to use it with mirrored screen option. This would be very popular with the people who run teleprompters.
I was trying to run the secondary screen on my Xbox One browser, (Microsoft Edge 18). unSurprisingly it did not worked, so I tested in my computer with the same version, the console reports that WebRTC is not supported.
I found that WebRTC is only fully compatible with Edge 79+ (the Chromium based). But there is an implementation called Object RTC that matches the edge version. I was wondering if it's not possible to somehow adds a polyfill to allow the client to runs on old browsers. I found this lib that adds a common layer that enables the protocol on a large range of browsers.
On Arch Linux, while trying to run the package from source, I get the following error when running yarn start:
yarn run v1.22.10

Looks like the relevant line is /bin/sh: line 1: react-scripts: command not found. It looks like react-scripts is a dependency in app/client/package.json.
This can be fixed with cd app/client; yarn install, then going back to project root and running yarn start.
I don't know yarn, and I'm not sure if it can handle running yarn install in app/client on its own; if so, it should be configured to do it. Otherwise, there should be instructions in the README specifying that it is necessary to run yarn install in app/client as well.
