  • I really appreaciate this database, it helps choosing the correct tv.

    The problem is that i cant seem to find the tvs you are testing in europe (sweden)

    Should i change the name or something?
    For instance:

    Thats the samsung you tested last year, it looks different and has another name in europe. Very confusing..

    Do you have any tricks to convert the name so i know that the tv in picking is the tv tou actually tested?
    Big thanks

  • Hello there!

    I was very happy to see such a low input lag for the LG UJ7700 but I would like to ask if there is a european model because I haven’t found it here in Greece.
    Also do you know if the 49″ has the same input lag?

    Thanks In advance!
