There are numerous things that could cause low resolution.
1. The very first thing to keep in mind is that any of the video conferencing platforms will downgrade your resolution and frame-rate due to your bandwidth constrictions from your network or your PC itself. These programs will downgrade video quality to ensure a steady video stream. With that being said there are very few programs that will actually give 1080p in a video call, and that is even assuming you have the network requirements to be able to stream at 1080p. If you want to test your camera in a program where you should be able to see it at full resolution try using our AMCAP program. You can download a free trial here.
2. If you have a USB 3.0 camera, make sure you are using USB 3.0 cables. The cable that comes with each camera should work so test it hooked up with just that cable. Also, make sure you are connecting to a USB 3.0 port on your PC; this is usually signified by a blue tongue on the USB port, or a SS (superspeed) written right above it. A USB 2.0 port being used, or a USB 2.0 cable being used, will result in a low resolution image.
3. If you are using an active USB extension this can limit your cameras functions on first use. If you plan to use an active USB 3.0 extension cable make sure to set up your camera connected with just the supplied USB 3.0 cable first, and once it is all set up, then install the active extension cable. If you have no issues while hooked up with just the supplied USB cable, but start seeing resolution issues when you install the extension cable, then that active extension cable isn't working. There are many low cost "USB 3.0" active extensions out there that do not cut it for video conferencing. We recommend using the Corning USB 3.0 extension cable as we have had no issues with it at all.
4. If you are still having resolution issues, try to use the AMCAP camera tuning software (from step 1). Once you install it, you should be able to select your camera in the "Devices" dropdown. If this image is also low resolution then you can go to "Options" and then "Video Device" and then "Capture Format" you should be able to adjust your resolution there (Output Size). Any adjustments done in AMCAP should hold through to any video conferencing programs.
