I want to know what devices to test on.
Note that our cert team doesn't each and every device and TV as that is not scalable. However they pick a group of devices that range from low - high end. The devices may vary from time to time, but the low - high end approach remains constant.
Best approach for your internal testing/QA is to test one device from each Code Name/Family in the Current and Supported Models lists (link below). An exception to this is when devices have the same processor and RAM (Amarillo 4K and Bryan) – in this case testing one is fine as both have the ARM Cortex A53 processor and have 1 GB of RAM
· Gilbert: 3900X or 3910X
· Amarillo 1080: 3800X
· Amarillo 4K or Bryan: 3810X or 4660X
· Liberty: Any 5000X model
· Longview: Any 7000X model
· Littlefield: 3700X or 3710X
· Cooper: 4620X or 4630X or 4640X
