We learned that Logitech's engineering crew was in a rush to get the product out, and the developed software from the existing codebase, but did not made the separation point between the touch-screen speakers. So, LCD Manager detects both displays correctly and you can set the plugins to work, but nothing will happen, making this one rather simple correction to make.
Even though the pairing between Z-10 and G15 seems unlikely, we know that the company has many more devices in store with the support for the very same LCD screen format that we have now seen on two different hardware offerings.µ
