Spacedesk для windows 10 как пользоваться

Primary Windows Machine (network display server)

The spacedesk server runs a Windows service and the WDDM Display Driver which is visible to Windows just as an own separate virtual graphics adapter (Windows 10) or as additional virtual display monitors on the primary graphics adapter (Windows 8.1). These additional virtual displays can mirror the main screen or extend the Windows Desktop. spacedesk DRIVER software is capturing their screen content, compressing it and transmitting it over the LAN (Local Area Network) to the spacedesk VIEWERs.

Drag Windows/Object: Tap two times for relative OR tap once for absolute, hold then drag.

The “Resolutions” dialog box of the Windows VIEWER Settings allows the users to use up to two resolutions. The client’s native resolution can be enable and use by checking the box of “Native Screen Resolutions”.Then the user can also add another resolution by selecting one of the typical screen resolutions on the combo box.

The “Automatic Connect” option of the Windows and Android viewer’s Settings allows the user to enable the automatic connect to IP address (of multiple primary machines) or hostname upon launching the viewer app and also an option to “Auto-reconnect” to the last server machine connected in case of sudden disconnection from system sleep or hibernate or from any kind of unwanted disconnection.

The “Auto rotation” option on iOS and Android viewer settings allows users to enable an automatic rotation of viewer screen according to current display orientation (eg Portrait or Landscape mode) of iOS / Android device.

Performance on wireless networks can be improved by configuring the Windows 10 PC/laptop or the mobile device as Wifi Hotspot / Wifi Access Point. Connection to this Access Point needs to be established before connecting spacedesk.

To configure the Mobile Hotspot option on Windows 10 PC/laptop. Just go to Start → Settings → Network & Internet → Mobile Hotspot, then turn it ON. Try to connect the client device(phone/tablet/laptop) to the wireless network name generated by the Mobile Hotspot. Then run the spacedesk VIEWER and connect to the IP address of server machine, in this case it should be the IP address of the Mobile Hotspot network generated (Microsoft Wi-Fi Direct Virtual Adapter).

spacedesk uses image compression to improve display performance. This mechanism reduces image size before transferring images over the network. The spacedesk image compression algorithm is lossy. It reduces quality and color depth of the image.
On fast networks, color depth and image quality can be kept very high while still achieving good performance.
On slow networks, color depth and image quality need to be reduced to achieve good performance.

The “Compression Quality” dialog box of the Windows VIEWER Settings allows the user to enable or disable the compression of screen updates. To choose OFF means to use RGBA 32-bit color format of screen image and no image quality reduction will be done. To choose On means that the user allows to reduce color depth by Chroma Downsampling and adjusts the compression quality to find the ideal image quality and performance speed.

YUV 4:4:4 – No reduction of color information. High quality of screen image but, performance intensive. Can only be used on very fast networks

YUV 4:2:2 – Reducing the color information by 1/3 (from 24 bit to 16bit) reducing color quality of screen image and improving performance.

YUV 4:2:0 – Reducing the color information by 50% (from 24 bit to 12bit) to achieve best possible performance.

The color loss caused by the above mechanism typically not very much noticeable for the human eye, especially when there is a lot of motion on the screen (e.g. playing a video). Thus YUV: 4:2:0 is the default setting which can apply to many user Applications.

The Image Quality can be varied between 100 (no compression) and 0 (maximum possible compression). The default value is 70 which still tends to show a clear enough and detailed enough image for many user applications.

The framerate option allows user to choose the FPS (framerate per second) on the viewer screen.
On Windows viewer just go to Settings → Compression Quality … → Frame rate per second (FPS).
On Android viewer, just go to Settings → Quality / Performance → Custom FPS rate.
On iOS viewer, just go to Settings → Quality → Custom FPS rate

Incompatible products:
Nvidia ShadowPlay
Wired XDisplay (splashtop)

Latest spacedesk Windows 10 Driver version now only supports Windows 10 version 1607 and above. Just run “winver ” to check Windows 10 version. If the version is older than version 1607 (Build 14393) just upgrade to Windows 10 version 1607 or above, in order to use the latest spacedesk driver. Use Windows 10 Update Assistant to upgrade Windows 10 to latest version for free, just click here…

In very rare Windows 8.1 environments a BSOD crash (Blue Screen of Death) can happen upon connect. Such a system crash is always recoverable because the driver is not yet active during Windows 8.1 system boot time.
Just reboot the primary machine in safemode then uninstall the spacedesk driver. To boot in safemode, press and hold f8 key upon computer reboot and before the windows logo appeared. Then in advanced boot option screen use the arrow keys to select the safe mode option then press Enter key.

Note: Before uninstalling using the spacedesk msi installer on safemode, run a Command Prompt then type the following commands:
Step 1:
for Safemode: REG ADD “HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\MSIServer” /VE /T REG_SZ /F /D “Service”
for Safemode with Network: REG ADD “HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\MSIServer” /VE /T REG_SZ /F /D “Service”

Step 2: net start msiserver

Step 1: Different Network Segments

If Primary Machine and Secondary Machine are in different network segments, then they cannot discover each other. However, they may still be able to connect. In that case try to add the IP address to detect the primary machine by clicking the ” + ” button.

To get the IP address of the Primary machine please check the above chapter Establishing the network connection .

Step 2: third party firewall software

In case the above steps did not help, then a third party firewall software (other than Windows Firewall) could still prevent detection. Please check this chapter’s paragraph ” Firewall Settings ” below.

Step 3: WiFi router’s network isolation active

Ihttps://spacedesk.net/user-manual/#item_492n case all above steps still did not help, and if this is happening on a wireless network, then there might be one other remaining problem: WiFi router’s network isolation feature might be activated. The only solution for this is re-configuring the router.

Step 4: VPN (Virtual Private Network) enabled

Just refer to the VPN topic below.

Step 5: Network profile

In some cases, setting the network profile from “Public” to “Private” solves the spacedesk network discovery issue.
To set, open the Windows Settings -> Network & Internet -> properties of the current network, then select Private underneath Network Profile.

Step 6: Alternative ways to connect

If all above connection attempts failed. Try USB Tethering or Wifi Direct / Hotspot setup to establish a network connection between Primary and Secondary machines.

This shows that the primary machine can be reached over the network but connection fails after the indicated connection time. Possible reasons are the following:

– Unstable network connection
– Error on spacedesk Primary Machine
– Nvidia ShadowPlay (screen record) is running which is a known issue at the moment.
– Virtual Private Network (VPN) enabled

Third party firewall

If there is a third-party firewall software or anti virus (eg Avast, AVG, etc.) with own firewall settings running on Primary Machine, then this can prevent spacedesk discovery and connection.

Please ensure that C: \ Windows \ System32 \ spacedeskService.exe is allowed through the firewall software or the spacedesk TCP / IP network protocol port is opened. spacedesk is using TCP port 28252.

In case there is a McAfee antivirus or firewall software installed, try the settings below or just disable it to check if spacedesk Viewer app can discover the Primary Machine. There is a known connection issue on spacedesk with McAfee software where after a few minutes of connectivity, McAfee on Windows is known to randomly kill and prevent network connections without informing the user.
Try to add spacedeskService in McAfee Firewall settings, click Ports and System Services then click the Add button.
System Service Name: spacedeskService
Local TCP/IP Ports: 28252
Local UDP Ports: 28252

Windows firewall

Please ensure that the Windows Firewall settings is correct. For details please check chapter Setup Primary Machine – Verify if setup was successful .

Check if spacedeskService is operating. Make sure that spacedesk service has started and spacedesk System Tray icon (at the bottom right of the screen) is visible in taskbar’s notification area and turned ON. For details, please check chapter above Setup Primary Machine – Verify if Setup was Successful .

Server OFF or ERROR

spacedesk server can be enabled and disabled via spacedesk server user interface menu. In case viewer app cannot discover / connect to the server, make sure that this menu is ON.
spacedesk server can be in ERROR state if spacedesk Graphics Adapter in device manager has yellow exclamation mark which indicates an error in driver. Check in C: \ Windows \ system32 \ drivers \ UMDF directory if “spacedeskDisplayUmode1_x.dll” is present then try to disable-enable the driver in device manager and try to switch ON in spacedesk server user interface menu.

For Windows 8.1 primary machine, check for “spacedeskHookKmode.sys” in C: \ Windows \ system32 \ drivers directory, then reboot.

For Windows 10 (version 1607 – later) primary machine, open Device manager and check below Display Adapters if spacedesk Graphics Adapter is installed correctly and enabled.

Step 1: Check if system tray bubble reports incompatible display hook driver

This error message indicates that another WDDM filter hook display driver is present on the system.

The specific display hook driver  can be determine via spacedesk Driver Console app -> DIAGNOSTICS -> Incompatible Software.

Step 2:Uninstall known products using incompatible display hook drivers

This is usually installed by a USB-Display or Zero-Client of the following brands:

Display Link, Duet Display, Fresco Logic, MCT, Microchip/SMSC, OSBase, Splashtop XDisplay and Extended Display HD, etc.

Display hook drivers are not standard Windows drivers. All products relying on such drivers are incompatible with each other. They cannot coexist on the same system. This includes spacedesk.

Use the Uninstall button on the spacedesk Driver Console app to uninstall the other product / hook driver detected, then reboot the spacedesk server machine and try to connect spacedesk client again.

Step 3:Uninstall splashtop wired XDisplay’s virtual display driver

splashtop wired XDisplay’s virtual display driver needs to be uninstalled (it’s an incompatible old legacy WDDM Filter Hook driver which cannot coexist with other similar products like spacedesk even though it doesn’t even seem to use this old driver any more).
On Splashtop Wired XDisplay Agent window -> Advanced, just uninstall the Virtual Display driver.

Step 4:Check if incompatible products did not uninstall OSBase driver

Various products using the OSBase driver do not properly remove it upon uninstall (e.g Duet Display, Fresco Logic, etc.). After uninstalling their product, the leftovers of the OSBase driver still need to be removed manually following the instructions below:

• Go to Control Panel -> “Add Remove Programs “. If you can find OSBase display driver software, uninstall it.
• Check if OSBASE drivers are installed by running the following commands:
  • “sc query ddkmd “
  • “sc query ddkmdldr “
  • “sc query ddmgr”
• If installed, uninstall OSBASE drivers by running the following commands:
  • “sc stop ddmgr”
  • “sc delete ddmgr”
  • “sc delete ddkmdldr”
  • “sc delete ddkmd”
• Reboot your PC.

Installation repair can be done by running the same msi installer version then select Repair button. Or just go to Windows Control panel → Programs and Features then search for spacedesk Driver, right-click then repair. This procedure only applies for Windows 10 primary machine only.

Detached Second Display.

In case of black screen  in Windows desktop application or always connecting status on HTML5 VIEWER or “Connected – Display OFF” message showing in Android/iOS VIEWER:
For Windows 11/10 primary machine, open the spacedesk Driver Console and click the connected client to check the Display Mode if it’s detached.

For Windows 8.1 primary machine, click the spacedesk Server window on the task bar and check if status of the device on Network Connections (remote) tab is “detached”.

To attach,  open the Windows Display settings of the primary machine, click the detached secondary display and try to attach it by selecting extend or duplicate.

Mirror mode failed.

For Windows 8.1 primary machine, if desktop extension is working but duplication is always failing, make sure that the “Settings → Resolutions → Other Screen Resolution” of Windows VIEWER OR the “Advanced Performance Options → Custom Resolution” of HTML5 VIEWER OR the “Settings → Resolution” of Android VIEWER, OR Settings → Display → Custom Resolutions of iOS VIEWER should matched the native resolution of the primary machine’s monitor.

For Windows 10, if duplicate option is not available in Display settings try to update the graphics adapter by Windows Update or manual download of driver from official website.

If duplication is still not available after driver update, then it’s probably because the driver does not support mirror mode anymore. Please refer to Known issues chapter below for Mirror mode not supported.

Clear All Display Settings.

In case display is in wrong settings (orientation, screen resolution, display detached) upon client connect, try the “Clear All display Settings” option in spacedesk System Tray menu.

Make sure that the VIEWER version is updated. To check just open the Settings → About of Android / iOS / Windows viewer app. While in HTML5 Viewer page, current version is displayed on the page below. Then compare the version on the viewer to the current version on the spacedesk website.

Step 1: Delete cached files, images and cookies of web browser.

If spacedesk HTML5 VIEWER web page doesn’t load the latest version 0.9.10, just delete the cached files, images and cookies on browsers settings.

Step 2: check if the web browser supports websockets.

If the spacedesk HTML5 VIEWER is unable to connect, check the version of the web browser and make sure that it is updated. If the secondary machine is a smartphone or tablet device the browser and OS needs to be most recent versions supporting websockets. Just go to https://websocketstest.com/ to verify.

Error Code: 1 & Error Info: 0

This error code and info indicates that the viewer cannot find the Windows server on the network. Mostly, this is caused by Virtual Private Network (VPN) enabled on the primary machine. For more details, kindly refer to the Troubleshooting Network connection – Connection Error chapter above.

Error Code: 1-2-3 & Error Info: 0-3-5

This error indicates that the primary machine can be reached over the network but connection fails after the indicated connection time. Check the Connection Error chapter discussed above.

(android) (iOS)

These error message box also shows the connected time, it indicates how long the viewer is connected before it disconnects. And in case procedures did not help, just report this error code sequence to spacedesk support.

Custom Screen Resolutions

On iOS and Android viewer, custom screen resolutions available on settings are only those not bigger than the device’s native screen resolution. This is due to the black screen problem observed when switching to higher resolution. On Windows and HTML5 viewer’s Settings → Resolutions… → Other/Custom Screen Resolutions, supported resolutions is up to 4096×2160.

Performance in HTML5 VIEWER

HTML5 VIEWER is much slower than native viewer apps on Android, iOS and Windows. This is due to technical limitation of HTML5/Javascript.

Slow screen update on Windows VIEWER.

There are some cases that the rendering of screen update in Windows VIEWER is very slow. One of the possible reason is that Windows client machine only has a DirectX 9 graphics driver. It is recommended to upgrade to DirectX 10 – above graphics driver to achieve better performance.

Multiple Display

As of now, spacedesk supports simultaneous connection of up to sixteen additional displays.
– Up to sixteen Android, or iOS, or Windows VIEWERs
– One HTML5 VIEWER web browser application for any device and operating system e.g. Mac OS X and Linux

HTML5 VIEWER on Mozilla Firefox and Microsoft Edge not supported.

spacedesk’s HTML5 VIEWER is currently not supported in Mozilla Firefox web browsers due to performance limitations. Please use other web browsers recommended in system requirements chapter.

This only applies on Windows 8.1 Primary Machine.
