Splashtop black screen Android
We had a few issues when remoting access to the Android mobile to give support. It was connecting but then a few seconds later it turns out blank screen from the technician's side. We kept asking to kill the app and redo it again and it happened all the time. It turned out that after the user managing connecting the remote access, the user holds the phone and put it close to ears as there was a noise and could not hear from the speakerphone. It turned out that every time the user does this, it triggers the blank screen from the technician's view. We advised the user to put the phone into a speaker or using Bluetooth earphone and leave the phone on the table. It is a simple solution but it took awhile to figure our what it is.

In some cases, when spacedesk is connected over USB tethering connection, the USB driver used by USB tethering network causes a BSOD crash. When changing Windows to multimonitor configuration, then sometimes the main display monitor remains detached from the Windows Desktop. Such “Black screen Problems” sometimes happen on all Windows displays. E.g. this also happens sometimes when working with projectors. This situation can usually be solved easily by changing Windows projector settings using “Windows Key + P” (where P stands for projector). Just repeat this key sequence: “Windows Key + P” “Arrow Down” “Enter”. Incompatible products: Nvidia ShadowPlay Wired XDisplay (splashtop) Desktop duplication of primary monitor to other displays is disabled in Windows display settings of Windows 10 with old version of graphics adapter (< WDDM 2.0). Just download the latest driver version from its website OR if it did not work try to downgrade the graphics driver to Microsoft Basic Display driver via device manager. 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…
Multi-GPU Technology such as Nvidia SLI Technology or AMD Crossfire is currently not supported by spacedesk. In case SLI is enabled, spacedesk will not work properly. 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. 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 Nvidia ShadowPlay – Current spacedesk version has a known issue with Nvidia ShadowPlay. While Nvidia ShadowPlay (screen record) is active, spacedesk will give an error code 1-2-0 on the viewer side. Just disable it in order to use spacedesk.
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 softwareIn 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 activeIn 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) enabledJust refer to the VPN topic below. Step 5: Alternative ways to connectIf 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
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. Windows firewallPlease ensure that the Windows Firewall settings is correct. For details please check chapter Setup Primary Machine – Verify if setup was successful . On some situations, having a VPN connection present on either primary or secondary machine prevents the network discovery process between spacedesk server and client, which results to “Cannot Detect Primary Machine” or “Error code 1-0” in spacedesk viewer apps. There are various workaround that can fix this problem without completely disabling the VPN connection. 1. If VPN app has user interface with configuration settings that will let users select a specific apps to not use VPN, just add the C:\Windows\System32\spacedeskService.exe on this exception list. 2. Run “ncpa.cpl”, right-click the Ethernet or WiFi network icon then open the Properties window. Click on the Sharing tab and check the “Allow other network users to connect through this computer’s internet connection” box. 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 ERRORspacedesk 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. 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.
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 driversThis 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:Check if incompatible products did not uninstall OSBase driverVarious 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:
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.
In case of gray or black screen in Windows desktop application or always connecting status on HTML5 VIEWER or “Display OFF” message showing in Android/iOS VIEWER, click the spacedesk Server window on the task bar and check if status of the device on Network Connections (remote) tab is “detached” then open the windows display settings of the server machine. Just select “Display Settings” in spacedesk Server window menu button then 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. 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.
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.
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: 0-3-5This 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.
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 VIEWERHTML5 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 DisplayAs 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. |
