    válasz Fisha #55 üzenetére

    Talán megleltem a választ, de azért továbbra is kivi vagyok más véleményekre, tapasztalatokra, infókra is.

    Röviden: igazából félképeket rajzol a panel 240Hz-en. Így 5-5 félkép pulldownnal megoldható a juddermentes 50%-os bfi.

    "24Hz x 5 = 120Hz. The 2019 WOLEDs have a split column refresh architecture supporting a 120Hz native refresh rate and a 240Hz effective refresh rate. This means that while the top half of the new frame is being written onto the top half of the array, the corresponding lines of the bottom half of the array can be written to black (blanked). After the last line of the top half is written with new frame data, the functions swap so that the top half blanks a line while the bottom half writes new data to the corresponding line. The net result of this is a 'rolling scan' of 50% screen height (only 1/2 of the screen illuminated at any instant. So it's 5:5 pulldown (5 repeats of the same frame) refreshing at 120Hz on a panel supporting a 50% BFI as a half-screen rolling scan at an Effective Refresh rate of 240Hz."
