Thank you for your information. I'd choose TV screen because it is easier to manage by us, who is not living in Thailand. To my understanding, we can simply send the USB key with the correct format of content inside to play it on the TV. Whereas monitor will be more complicated to use.
I also found that the TV frame is thinner than the monitor frame as per photo.
Please ensure that we'd like our TV to be inserted into the wall, so that it is flush to the concrete wall. So the hanger behind shall allow us to pull the TV out in order for us to insert the USB key.
