Celeron CPUs with Intel HD Graphics can support Miracast.
1. I'd just like to confirm, can Celeron G1820~40 series support it?
2. And if it is supported, do I need any other specific component on the PC end to use Miracast? (for example, specific graphic cards?)
Hi ptsu, I am glad you are asking these questions. At this moment only the following Intel® Celeron Processors support Miracast* (besides the ones listed in the FAQ):
A supported wireless adapter from the list below will be needed too; however, only Windows* 8.1 and the most recent Intel® processors support Miracast*as noted in the FAQ you linked above. The graphics controller is included with the processor.
