The two above answers have some limitations (see 1+2 below).
1. Lea’s answer is correct but it needs spacedesk Video Wall option enabled.
Video Wall mode has slightly less performance than regular mode.2. DennisW87 is talking about hardware graphics adapters. I doubt that this is relevant here.
spacedesk is all about adding USB or networked displays without any graphics adapter hardware.3. The ulimate answer: Windows actually does not support mirroring more than two displays.
However, you can use the trick below:
=> Go to spacedesk server window and click “Clear All Display Settings” on menu
=> Connect up to 3 spacedesk viewer and make sure that all viewers are in extension mode
=> Press “Windows key + P” combination, then select “Duplicate”
PS: This will only work if your primary machine is Windows 10 or 11 and has latest graphics adapter
supporting WDDM 2.0-above driver model (you can check it by running dxdiag.exe).Glad to discuss this a bit more in detail below:
1. Game stuttering probably doesn’t originate from difference in frame rate. Probably it rather comes from game and spacedesk encoding competing for CPU resources.
2. Framerate cannot easily be increased because spacedesk is using CPU encoding for each frame (this applies to both USB and network connection). CPU load would increase and even latency might increase since encoding would possibly take more time.
3. Hardware encoding by spacedesk would be prerequisite for increasing the framerate. Even without increasing the frame rate it might be the solution for the above named problem. Even at the existing frarate the stuttering might decrease if the game has enough CPU resources available (not taken away by spacedesk CPU encoding any more).
Now the big question: When will spacedesk support hardware encoding?
The answer: No specific scheduly yet…Yes, this dump points to a device driver software named chdrvr01.sys
When googling for chdrvr01.sys it seems to be delivered by a company named “CH Products” which seems to manufacture flight yokes, rudder pedals, throttles and joysticks.
Only this company can solve this problem with their software.
Please contact their support or uninstall their product (or at least remove their device driver software).Response to Post 1 above:
Let us start a comprehensive analysis first. spacedesk Driver/Server is running on which Windows version? Windows 10 or Windows 11? Which spacedesk Client Viewer? We assume Android because we read your rant in the Google Play store reviews. This also sounds as if you already figured out by yourself that “Virtual Desktop” is causing exactly such behavior. There is nothing we can do about it. We cannot fix other companies’ products like e.g. “Virtual Desktop”
BTW: You said that you already saw “all of the troubleshooting procedures viewing the forums”. Did you also see the instruction manual already? It is available on https://forum.spacedesk.netuser-manual/Are you using one of the following devices below?
2012 iPad (gen 4)
2012 iPad mini (gen 1)
2012 iPad (gen 3)
2011 iPad 2
2010 iPad (gen 1)Apple officially does not support updates nor installs for the above old devices and operating systems any more.
Source: https://developer.apple.com/support/xcode/FIRST: This is the nature of BETA versions (in modern era and in old eras).
SECOND: We did not break anything. We are smoothly phasing it out by showing black and white screen. It remains fully usable.
THIRD: As usual and common for BETA versions – a newer better version is available immediately when a BETA expires.EXPIRY of OLD BETA VERSION!
Old BETA versions switch to black and white when they expire.
Many old BETA versions expired on December 31st 2022.
Please update to the newest most recent Version of BOTH spacedesk Driver software (Beta RC v1.0.50) for Windows PC AND spacedesk Viewer software for Android from Google Play Store.We changed priority to favor “Android USB cable support” over “h264 encoding”.
Android USB cable support is already working.
Android USB cable support will become available publicly within the next few weeks.
h264 encoding might not even be continued after this (too many quirks, performance gain too small for regular users).
Instead we are currently evaluating WebRTC network communication protocol for larger performance gain.
WebRTC software can implicitly use h264 encoding anyway (by software as well as hardware-accelerated).spacedesk SDK is used by world leading medical imaging device manufacturers, conference room equipment manufacturers, PC manufacturers and semiconductor manufacturers.
spacedesk SDK is a B2B (Business to Business) product which is only sold to corporate customers.
To proceed further, we need a full company name and address and a contact person within this company including telephone number. Just send an email to info(at)spacedesk.net Do not publicly post contact information here.First we need to analyze if your problems could be related to spacedesk in any way at all (which is actually very unlikely). Please send us the following:
– run dxdiag.exe on your primary machine, click “Save all information” and send us the output file
– spacedeskSetup.log file located in C:\Users\Public
– setupapi.dev.log file located in C:\Windows\INFPlease save all requested files in one folder, then right-click -> Send to -> Compressed (zipped) folder, then attach the *.zip file on your next reply.
