@Ari please, try to find any solution with your team on these issues mentioned by @fonix232 or post some updates on this topic.
I can confirm this issue too: "after about 2-2.5 hours of usage, there's a visible jump as the device "focuses", only to ruin the currently established focus. The device is NOT moved during these times, and is sitting peacefully on a chest of drawers, completely stable."
Has anybody problem with HDMI and PS/STB like this guy?
