Thank you for contacting us. We took some pictures of both TVs playing a DVD movie (480p) and focussed as much as possible and without having too much visible moire, to show the most details possible in the final upscaled image on both TVs. As you can see on both pictures, the TCL C807 does smooth out straight lines a bit more than the Vizio P Series 2017 and the image is also a bit less noisy, but this is a bit less visible on the test picture. We did a side by side comparison with a HDMI switch, and we came to the conclusion than the TCL C807 still looks a bit better than the Vizio.

This is a very similar result as the test we did, comparing the TCL P607 upscaling to the Vizio P Series 2016. As you can see in the picture above.
