The first thing you should consider is the size of the classroom. This will help you decide the size of the Smart TV or the panel. We must ensure that students, irrespective of where they are sitting in the classroom, should comfortably be able to look at the content being played without any stress on their eyes. Second thing to look at is the reputation of the brand and availability of service centres. Branded Smart TVs require minimum maintenance, but when needed, we should have close and immediate access to their service engineers. We would always recommend going for a brand which has a service centre located close to your project locations. If possible, avoid going for cheap and assembled Smart TVs. Third thing is of course the pricing and your budget. The reason we have put this as the third factor is because foremost, we should look at the learning value. It is okay to do a project in a lesser number of schools, but the objective should be to give them a hardware which is of good quality and will last a very long time.
