Hi,
Can my MacBook Air show any picture in any resolution (that is at least 720p) on the external display? I have a miniDP to HDMI dongle. The display is Avtek Touchscreen 5 connect 65.
The short answer is yes it should work. Refer to Use an external display with your MacBook Air - Apple Support.
To be completely accurate your MacBook Air has a Thunderbolt port, which superseded the older Mini DisplayPort. That could be relevant if your Mini-DP to HDMI adapter is not compatible. For a description and some helpful illustrations please refer to Identify the ports on your Mac - Apple Support.
Can my MacBook Air (2013, 13 inch) show any picture on 65" external display (3840 x 2160) through miniDisplayPort?
