Dear all X8 & X8-H (X8-H Plus) users, I'm writing to apologize to any of you who are suffering from the problems of switching to 4K output resolutions after the most recent firmware update (December 2014). Problems exhibited as follows: 1.) Unable to switch to 4K resolutions; 2.) Screen flickering after swtiching to 4K resolutions; During the 2 weeks of investigation we have confirmed the issue is caused by some wrong "register" values present in Amlogic's latest SDK. Their team has been very co-operative working out a fix and I'm here to announce that this problem will be fixed in the coming update via FOTA (users with Decemeber 2014 firmware), full image and USB .zip update package (users with any older version of firmware). Our release schedule will be within January 2015 (within 10 days from now). In the future, we promise we will double-check those basic features when we are upgrading to newer SDKs to avoid such problem from happening again. We've made a wrong assumption that these settings were not changed. Again we are truly sorry about the inconvenience caused, please sincerely accept our apologies. Best Regards, Team MINIX.
