A:AnswerHi Stosh - All of the apps you have mentioned are either preinstalled, or available to download directly from the Q60A's built-in App Store. ^Gina
A:AnswerAccording to the on-line owners manual, the TV displays 16:9 or 4:3 picture sizes which are both landscape. I searched the entire manual for "portrait" and image orientation and found nothing. So it would appear the answer to your question is NO. You might take a look at computer monitors instead of a TV.
A:AnswerFirst try to go into the TV setting for sound and see if you can change the setting to RCA or the HDMI. I had to change the settings for my HDMI soundbar. Another option is to buy a Bluetooth adapter and send the TV sound to the adapter for your external receiver using the Bluetooth from the TV. I have two older powered speakers I wanted to use, when I did not need the soundbar, speakers attached with a Bluetooth adapter and set the TV to Bluetooth and it works flawlessly. You can buy a Bluetooth adapter for around $25/30 bucks.
A:AnswerHi! If your hearing aids utilize a wired connection, you can connect them to the Q60A TV via Optical or HDMI cable. If they are Bluetooth enabled, you can wirelessly connect them via Bluetooth. ^Gina
