Also i'm suffering from gpu throttling when playing games, videos.
BIOS update would solve this issue as already reported in this forum.
Are there models within models of the x770-107 and I bought an older one? Or do all x770's have built in emitters!?
This depends on notebook model you have purchased.
Some X770 supports an internal IR emitter.
As far as I know the internal 3D vision IR emitter should be placed on the right hand side near the internal webcam built in the display frame. The IR emitter sends signal to wireless 3D glasses.
By the way: the 3D glasses can be used for about 40hours. Then the battery is empty and needs to be charged. The USB cable provided with the glasses allows you to charge the glasses battery. (light flashes amber when charging)
