video pass through
is video pass through the same as video up conversion?
No they are 2 different things.
Up conversion means the device can take a lower quality signal and bring it to a higher quality. Here is an example Device A sends out a 1080p signal and Device B upconverts it to 4k(UHD) and sends it to Device C.
Pass through is when Device A's signal can move through Device B and remain the same quality. An example is Device A sends out a 4k signal, Device B has 4k pass through so the 4k Signal is able to move through Device B and to Device C.
