HTC One M8 screen mirroring

[AC Question]

so i have a HTC one m8 and want to know whats the best option for screen mirroring to my tv, specifically with higher end games in mind. i have come across so much conflicting information and there is such an array of devices/dongles, apps ....etc. I know chromecast is the easiest option but i have read that its mirroring feature is not fully supported on the htc onem8. i see there are roku devices, miracast devices...etc

could someone point me in the right direction
