Hi @cavogaro,

For clarification, so you want to mirror your main monitor screen to your other Android TV screen, right?

If this is the case, it is possible, just that Windows Display Control Panel/Settings user interface does not support it.
This applies to spacedesk and all other displays.

We suggest the workaround steps below to mirror your main monitor to all your Android TV screens.
1. connect your 2 other Android TV, so the setup will be something like this:
— Android TV #1 – main screen (1920×1080)
— Android TV #2 – extension (1280×780)
— Android TV #3 – extension (1280×780)

2. Open spacedesk Driver Console and enable Videowall mode
3. Assign all clients connected to Video Wall.
— You will see on Connections -> Active (2 connected), 2 Android TV clients connected, click one of them, then click the Videowall tab in the right panel
— In Wall Index box, enter any value e.g. “1”, then it will create a Video Wall1 underneath CONTROL
— Change the dimension (Width:Height) of the client from 1280×780 to 1920×1080
— Then right-click the other Android TV client below, then select “Assign to Wall1” and also change its dimension too
4. Change dimension of Video Wall1, by clicking it underneath CONTROL, set the Size (Width:Height) to 1920 : 1080
5. Open Windows Display Settings, and you will see an extended display (this is the videowall 1), switch it to Duplicate the main display.
You can do it via Display switch (Windows logo + P hotkey) then select Duplicate.

Hi @corbil,

Unfortunately, duplicating your Android phone screen to Windows machine is not possible with spacedesk.
spacedesk only supports Windows 8.1/10/11 as primary machine.
You can only use your Android device as secondary machine.
For more info, please check the chapter System Requirements in the user manual https://forum.spacedesk.netuser-manual/.

Hi @bugmenot,

spacedesk Pro license will be available very soon. No specific date of release yet.

As for your other question, creating a virtual display without spacedesk client connection is not available in the current spacedesk BETA version.
But there’s a workaround to create a virtual display (without connecting from secondary client).

Option #1: Use HTML5 Viewer page to connect locally. Just open a web browser e.g. Microsoft Edge on your primary machine, then go to http://viewer.spacedesk.net/ and connect to the localhost’s IP address or 127.0.0.1. Keep in mind that spacedesk only allows 1 HTML5 Viewer connection at a time.

Option #2: Connect a secondary client at first to attach a virtual display and persist it. To do this:
– open spacedesk Driver Console and switch ON Videowall mode
– set Videowall disconnect delay to -1 (equivalent to infinite)
– connect a spacedesk client first and disconnect it immediately, you will notice that the secondary display will persist (check it in Windows Display Settings). It will only detach once you reboot your machine or switch OFF spacedesk Driver or Videowall mode in spacedesk Driver Console app.

Hi @beckett,

We have similar reports regarding connection problem when using public wireless network.
Typically we cannot troubleshoot networks in public places.
We assume that one reason might be the hotel’s wireless router settings could have wireless isolation enabled.
With this settings, it will prevent direct communication between the connected devices/machines.

You might need to setup your own private network between your Mac and Windows primary machine in order to connect spacedesk (e.g. WiFi Direct/Hotspot).

[spacedesk Lea]

Hi @mr-robot,

Yes, indeed. This is an important feature that will only be available in Pro version.

In case you experience this scenario, you can still get back the control on your primary machine.
Just blindly press the Display Switch hotkey (Windows logo + P) on your primary machine’s keyboard until you re-attach your main monitor screen.
No need to forced reboot/shutdown your primary machine.

Hi @kyun,

Can you please tell us what page are you trying to load with spacedesk’s port (28252)?
Are you trying to load/open the spacedesk HTML5 Viewer page via web browser?
Are you trying to connect spacedesk locally via HTML5 Viewer?

Can you maybe send us the screenshot/s of what you are trying to do?

Hi @samsonandersson,

Current spacedesk BETA version:

– supports touchscreen on one viewer display only (on first client to send touch input), then it will use a single mouse touch input on other displays connected

– consumes GPU and CPU, the amount it consumes depends on how big the display resolution is and how many spacedesk displays are connected

– is not yet GPU configurable, spacedesk cannot select which GPU to use. spacedesk is always using the default main graphics adapter of your primary machine. This feature will not be available any time soon.

– To achieve a better performance, spacedesk connection must be over a direct wired connection (LAN cable and/or Android USB cable).
For more info please check the chapter Performance tuning in the user manual https://forum.spacedesk.netuser-manual/.

[spacedesk Lea]

Hi @flyingace63,

Thank you very much for sending the diagnostic logs.

Based on the logs:

1. You have a detached secondary display.
Have you tried attaching it via Windows Display Settings -> Multiple displays -> Extend/Duplicate display?

2. As for disabling the Virtual Desktop & Virtual Desktop Streamer, please also try to uninstall it (then switch spacedesk Driver OFF-ON via spacedesk Driver Console) and check again with spacedesk.

[spacedesk Lea]

Hi @patatowarz,
Unfortunately, spacedesk does not support connection of 2 Windows PC via type C USB cable.

Hi @aspect,

If the spacedesk Android USB Cable is ON, it disables the other USB cable applications (e.g. File Transfer).
To disable it, please open the spacedesk Driver Console on your primary machine, click Communications Interfaces then switch OFF Android USB cable.

[spacedesk Lea]

Hi @rexmauris,

Routers can cause lags and latency. Bypassing them always improves performance.
This does not only apply to USB Tethering, but also to direct ethernet cable connection and WiFi Direct connection.

If your secondary device is Android, you can try connecting via direct Android USB cable.
Please refer to the chapter Direct USB Cable Connection (Android only) in the user manual https://forum.spacedesk.netuser-manual/#item_11689.

Otherwise, please check the chapter Performance tuning in the user manual.
It provides several ways to improve performance. https://forum.spacedesk.netuser-manual/#item_505.

Hi @jptang2,

spacedesk does not work with VPN enabled most of the time.
That’s why we always advise the users to disable it.
In some cases it works and just needs a workaround.
For more info, please check the chapter Troubleshooting -> Network Connection -> VPN (Virtual Private Network) in the user manual https://forum.spacedesk.netuser-manual/#item_493.

Hi @david-p,

Yes you can simulate an 8k virtual monitor with spacedesk.
Just enable the videowall mode, then create a video wall by assigning a client to a wall.
The default dimension of a spacedesk video wall is 4K (3840×2160) but you can modify it and set an 8K resolution.

For further assistance, please refer to the chapter Videowall Configuration in the user manual https://forum.spacedesk.netuser-manual/#item_619.

Hi @rhoads,
Do you have Night-light or maybe HDR enabled on your main monitor?

[spacedesk Lea]

Hi @sicey,
Is it the display scaling on your main monitor or in spacedesk display?
These are probably the reasons:
1. Outdated graphics adapter driver. Please make sure to update your main graphics adapter.
2. The monitor maybe does not support display scaling in a 720p resolution.

[spacedesk Lea]

Hi @benscripts,
spacedesk does not require internet data.
It only needs the machines (both primary and secondary) to be connected on the same local area network.
spacedesk should not consume your wifi data.
Only applications that access the internet (e.g. web browsing, downloading, etc..) will consume the data.

Hi @dmanz56,

How long before the lag/unresponsiveness happens when using the USB connection with Air Manager for MSFS2020?
Does it also happen with other games/apps? Or only when using MSFS2020?
Can you please check if there’s a high CPU/Memory/GPU usage on your primary machine via task manager when it happens?

[spacedesk Lea]

Hi @patatowarz,
Did you set a static IP address (on both primary and secondary machine) when you setup a crossover (direct) ethernet cable connection?
Did you check if it shows 1Gbps network bandwidth on both machines.

If not, please refer to this article: https://helpdeskgeek.com/networking/connect-two-computers-using-a-crossover-cable/

Hi @patatowarz,

Thanks for sending the requested files.

Both primary and secondary machine shows 100Mbps network bandwidth.
Is it a direct crossover ethernet cable connection? Or does the network connection still goes through the router?

Can you also check for any high CPU/Memory/Network/GPU usage in your task manager while spacedesk shows low fps?

Not sure if this will help, but please also update the AMD graphics driver on your secondary machine.
You can download the latest driver from AMD website – https://www.amd.com/en/support.

Hi @pierrec12,

Thanks for the info.

For clarification, you got 5-6mbs network bandwidth when you start MSFS 2020, correct?
Can you quickly check without spacedesk viewer connected, and just run MSFS2020 on your machine and check again your network bandwidth.

Aside from iOS Viewer (from iPad), is there other viewer app connected (e.g. android viewer) when you received the “low network bandwidth” notification?
Current spacedesk Driver version should not trigger the “Low Network Bandwidth” warning message if you only have iOS Viewer app connected. This should only be shown if you have android viewer app connected.

[spacedesk Lea]

Hi @demon0616,
spacedesk Driver for Windows 10/11 does not support ARM processors.

[spacedesk Lea]

Hi @jamiedolan,
Is the warning message popping up on android viewer screen? or in your Windows primary machine? or both?

[spacedesk Lea]

Hi @legna,

Thanks for the reply.
Unfortunately, we cannot open the zip file (and it’s not the right diagnostic folder we need for analysis).
Please follow the steps above on how to get the diagnostic logs via spacedesk Driver Console.
spacedesk Driver Console app generates a diagnostic folder name like “2023-03-15-XXXXX-spacedeskRuntimeDiagnostics” (which contains all necessary diagnostic log files), then this is the folder that you should compress (zipped).

[spacedesk Lea]

Hi @dave_25,
It is possible, just that Windows Display Control Panel/Settings user interface does not support it.
This applies to spacedesk and all other displays.

You can mirror screen 2 to all your iPad screens using spacedesk Driver Console with Videowall mode enabled.
Just follow the workaround steps below:

Let’s say you have these displays on your setup:
screen #1 – main display [1920×1080]
screen #2 – spacedesk iOS viewer [1920×1080]
screen #3 – spacedesk iOS viewer [1920×1080]
screen #4 – spacedesk iOS viewer [1920×1080]

1. Open spacedesk Driver Console and enable Videowall mode
2. Assign all clients connected to Video Wall.
— You will see on Connections -> Active (3 connected), 3 iPad clients connected, click one of them, then click the Videowall tab in the right panel
— In Wall Index box, enter any value e.g. “1”, then it will create a Video Wall1 underneath CONTROL
— Then right-click the other 2 clients below, then select “Assign to Wall1”
3. Change dimension of Video Wall1, by clicking it underneath CONTROL, set the Size (Width:Height) to 1920 : 1080

[spacedesk Lea]

Hi @pierrec12,
Currently spacedesk allows up to 16 viewer connection simultaneously (via network) and I guess this also applies to USB cable connection.
But we are not focused on this feature yet.

Theoretically, connecting multiple android devices (maybe 2-3) via USB cable should work but it’s not fully tested yet.
Currently, our main focus is to make it work properly in 1 device and fix all known issues that we still have.

You can try connecting 2 of your android devices (via USB cable), and it should work though there are still some known issues you might observe.

[spacedesk Lea]

Hi @legna,

How many spacedesk Viewer apps are you trying to connect?
Are you using spacedesk Windows Viewer app?
Is it from Windows Store? Or Windows 7 Viewer (desktop version 0.9.40) from the website?

Is your primary machine Windows 10/11?
If yes, please send us the diagnostic logs of the issue for analysis.
Just follow the steps below:
– open the spacedesk Console window app by clicking the spacedesk tray icon on your task bar’s notification area
– click the Diagnostics on the left side panel
– if Debug View is not available, please click the download button first
– switch Diagnostic Collection ON (make sure to click Yes in the User Account Control box to proceed)

Hi @atlas-meow,
Thanks for re-attaching the image.
This looks like a known issue of spacedesk with 10-bit pixel format enabled in your main graphics adapter settings.
If you know where to configure it, please try to disable then reboot your primary machine.

Otherwise, we can assist you on how to disable it. First, can you tell us your main graphics adapter? Is it Nvidia or AMD?
For detailed info, could you please send us the diagnostic logs of your primary machine using the spacedesk Driver Console.
Just open the spacedesk Driver Console -> Diagnostics, then click the Save All Information button.
