Android player video screen is not very good? (TV problem)

The 1185 player has been used before, the effect is very satisfactory, whether it is local video or online video, are very clear, by the way, even if the 480P video, the TV is still better than the 480P 1080P clear.

The only thing I didn't like was the player of 1185. It was inconvenient for me to play the video on the webpage. So I transferred the player of 1185 to others and bought the A9 dual-core, ALC8726 1G. After installing the test, first play the local video, very disappointed, compared with 1185 can be said that the screen is very rubbish, the first resolution is very low, the TV set 1080P, no broadcast video before the interface is still acceptable, although the system displays the current resolution The rate is 1280X720, but when playing video, the resolution becomes extremely low, and I estimate it will be 320P. The resolution is low, and the color depth is also very low. I suspect there is no 16-bit color depth? The color transition is very unnatural and there are many color patches.

I began to think that it would not be a case? For all 3-4 players, they all died, tried to play online video, use PPTV (HD), and after entering, I seem to understand what: video introduction pictures are all blurred, nothing can be seen, it looks like A one-inch picture will be directly enlarged to a 10-inch effect, for other video platforms, the same situation, the current situation is like I use Iphone software on the IPAD.

I am ready to return the product. Does Android's video simply do not support large-screen display? Can only support up to 10 inches of screen?

1185 was looking at the Panasonic 50-inch old TV at home, poor performance, so I feel a sense of grain is not strong, Android machine is sony 52-inch, relatively new machine, the display is too clear, but strong grainy, plus play When the video actually shows a decrease in resolution, it gives me a feeling that it's a lot worse, if you mislead everyone's embarrassment.
However, when the video is played, the resolution drop is a real one, which has more or less influence on the effect. In addition, it is also true that the PPTV HD shows that the image is blurry. The others are all fine.
