Our Verdict
LG UJ7700
LG UJ6300
The LG UJ7700 is better than the LG UJ6300. Unfortunately, the UJ6300 has issues with temporary image retention and static images can remain visible on the screen for a few minutes after they have been removed. The UJ7700 does not have this issue. The UJ7700 also has an extra HDMI port compared to the UJ6300. Both TVs use a slightly less accurate sub-pixel structure which may bother some people for PC use.
