    Hi, we are testing video wall functionality between two displays. We are using windows client and we see that image on edge between two displays are not fully in sync. Has space desk some internal line synchronization between clients?

    Hi drlikz,
    we still have known synchronization problem with videowall frames.
    Could you please send us the following info:
    Primary Machine
    – operating system (Windows 8.1/10)?
    – graphics adapter (AMD/Intel/Nvidia)
    – network connection type (wired/wireless/USB tethering/WiFi Direct)

    Secondary Machine
    – Viewer type (Android/iOS/Windows/HTML5)
    – network connection type (wired/wireless/USB tethering/WiFi Direct)


    Hi, we are using:
    Primary Machine:
    – Windows 10
    – Nvidia
    – wired

    – Secondary machines – we tried many possibilities till today:
    – 1. win10 laptop intel card, 2. win10 PC nvidia card – result un-synced displays
    – 2. low-cost android tv boxes, 50$ each, – result: slow processor
    – 3. 100$ smart android tv boxes, – result: still slow processor
    – 4. apple tv (200$) – result: apple tv os not support spacedesk app
    – 5. android smart phones, one plus 8t + iphone 12 pro max – result: seems bit working, but as there are small displays we are not sure

    Now we are planinng test on nvidia shield tv boxes (200$).

    Big question is if there is some preferred devices what should be working.

    Are all these secondary devices connected over wireless network?
    Hint: Routers can cause lags and latency. Bypassing them always improves performance.
    spacedesk works extremely well on very strong cable network connections without routers in between.

    – 1. win10 laptop intel card, 2. win10 PC nvidia card – result un-synced displays

    Are you using the Microsoft Store version of viewer app?


    We always test it with cable connection and have one 1 Gb switch (not router) between spacedesk server.

    We are not using MS store version of client as it seems have older version than that installable package from your site. Now we go away from that windows client as we need 8 display connected and there is no possibility to have more clients on one computer and have used all nvidia hdmi output in use.
    Now we are focusing mainly to setup it on some android tv boxes. Our today test will be on
