A:AnswerTo my knowledge the unit doesn’t have chrome cast built in. I have not seen it while configuring or using mine. However as you can use any Samsung phone or tablet to cast to the tv natively on their cast platform as long as both devices are connected to the same network (wired/wireless).
A:Answer8MM, length is determined by the curvature of the back in relation to the mount. The mount came with multiple lengths of screws to allow for this. Very simple to mount.
A:AnswerThe standard VESA mounts will work, however the screws are the problem. I wrote about this in my review. You'll need M8 screws and the length will depend on the mount. You can use any type of a flush or swivel mount, but you'll want to measure or approximate the length once you have the TV and mount lined up. Basically be prepared to make a trip to your hardware stores to by various length M8 screws to get a tight mount. Unfortunately the length of the M8 screws in the manual is inaccurate.
