I constructed the following sentences and have provided translation and usages for each, although i am not sure if they are correct. kindly please correct me if i am wrong:

я смотрю на телевизор (i am looking at a television that is turned off with no show running.)
я смотрю на телевизоры (i am looking at different television models, not the shows running on them. For example, if i was at an electronic appliance store.)
я смотрю телевизоры (i am looking at many televisions that are turned on. for example, if i was a security guard watching different televisions providing video of different areas monitored by many cameras.)
я смотрю на машины (i am looking at different cars in an automobile shop)
я смотрю на машину (i am looking at a car)
я смотрю машину (i am watching a car, this seems incorrect)
я смотрию та машину (i am watching that car, a specific car)

спасибо!
