“In Roku's website, Roku 4 specification shows "Up-scales 720p to 1080p HD on 1080p HD and 4K UHD TVs". What Does it mean? Does it mean it can convert 720p video into 1080p?”

Yes, so if you're watching a show on the Roku that was originally shot in 720p like most TV shows, the Roku will upscale the quality to 1080p. The quality won't be as crisp and clear as native HD, but it's still a noticeable improvement.
Sorry, there was a problem. Please try again later.Sort of. What it means is that it takes a 720p video and attempts to estimate what the missing information and then fills it in to make a 1080p image. The quality of the resulting image varies greatly between devices.
Sorry, there was a problem. Please try again later.Yes. It will take a video stream from 720 and up-scale or digitally enhance the video to display at the 1080p resolution. It's not an exact or true 1080p quality but it is very close. It's better than just watching it at the original 720 stream. It applies the same logic to the already 1080p stream. It will up-scale that to 4K. It will look better than just plain 1080p, just not true 4K. Also, it can only up-scale once, it can't go from 720 to 4K.
Sorry, there was a problem. Please try again later.Yea it does, it provides the best quality possible, but in order to watch 4K, source has to be 4K, second if you have not bought it yet, I don't recommend you do, I've had nothing but problems with my Roku 4. I'm on my second unit and I wish I could return it for a refund.
Sorry, there was a problem. Please try again later.It means it will scale the 720p output to fill your 1080p screen possibly making it look crisper. It will not convert 720p content to 1080p quality but it will probably be difficult to tell the difference for most content.
Sorry, there was a problem. Please try again later.
