Q: I have plugged in the adapter and the USB ports work but when I plug in my monitors only one of them display anything, what am I doing wrong?
A: This display output of this adapter supports dual displays on MacBook's and MacBook Pro's with an Intel Chip. If you have a MacBook or MacBook Pro with Apple's new M1 or M2 Silicon chip only one external display is supported, this is a limitation created by Apple on the M1 & M2 chip

Q: So are you telling me that there is nothing else I can do? I just bought this MacBook and adapter and but I need two extra monitors?
A: We understand your frustration, but fear not, we do have a solution for you. Because this was such a common problem that affects so many people we had to find a way around the issue. We have 3 new products that use special chip sets called DisplayLink. This technology is like an external graphics card the accepts video output from a USB-A 3.0 or any USB-C port. When using a DisplayLink product on MacOS you need to install the DisplayLink Manger and allow "Screen recording" during the installation stage. Our CMDL22P has Dual Video Output at 1080p (Full HD) and other ports in a handy portable adapter. The Triple Display CMDL32D or Dual 4K CMDL24D are both full docking stations with Power Supplies

Q: My friend has a DisplayLink dock, I heard that its really slow and has to record your screen. Is that safe?
A: DisplayLink technology is from Synaptics, one of the worlds premier, largest and most trusted chip set suppliers.  Also the main choice for docks for the likes of Dell & Lenovo. Manufacturers and consumers love DisplayLink because it offers a solution to the USB-C video problem, it truly is Universal. We use it here with dual 4K screens running @60Hz for office work DisplayLink is so fast that in most cases you wont even know its running. If you are an extreme or demanding gamer however, this technology may not meet your needs but for everyone else it is perfect. As for ‘recording your screen’ well yes that's true, the technology essentially emulates and extends your desktop. You may encounter on a Mac or certain other operating systems a check-box during setup that asks you if you give permission for the DisplayLink manager to ‘record your screen’. If you do not accept the DisplayLink technology will not work, so the choice is yours whether you want your USB port to output video or not. Please understand though that this is already happening in Windows as this technology is built in to the Windows OS. Please remember, your screen is not being recorded by anyone externally, nor is any information being saved or stored externally or shared with anyone. The ‘recording’ is the DisplayLink graphics card recording your existing desktop then the chip uses this information to create your new extended screens

Q: The adapter is connected but is unresponsive, what should I do?
A: Sometimes after a longer period of inactivity the sleep function may not wake up in normal way. In this case, or if the adapter becomes unresponsive, first try unplugging and re plugging the USB-C connection, if this fails, disconnect the adapter from the power and re boot your system, if you are still having problems please contact Comsol support

Q: I plugged in my adapter but I get the same image on both screens. How do I get different images on each screen?
A: From the Apple Menu in the top left of the screen select "System Settings". Then from the list on the left hand side of the screen select "Displays". Highlight your desired display and in the option "Use as" select "Extended Display"
