posto nigdje nema samsunga le-32D550 koji je Full HD telka, da li je velika razlika ak uzmem 32D450 koji je HD ready?
Oce se opce primjetiti na tako maloj dijagonali razlika u rezoluciji?

ima ga, treba samo znati traziti

600hz je sub field drive, nema veza to sa 50 ili 100hz.
evo da ne pisem na hrv, jako lijepo objasnjeno:
Panasonic subdivides their plasma display panels into 10 sub-fields. Each sub-field is refreshed at a 60 Hz rate. 10 sub-fields refreshed at 60 Hz (10 x 60 = 600) produces a 600 Hz sub-field drive figure.
Is a 600 Hz sub-field drive better for fast motion? NO. It neither helps nor hurts fast motion on a plasma display panel. Plasma pixels switch at 1 micro-second; thousands of times faster than the fastest LCD response time. Because of this speed difference, a plasma TV operates different than a LCD TV and, therefore, does not produce the motion blur and jitter produced by a LCD display panel. Plasma TVs do NOT need 120 Hz refresh rates to compensate for these motion artifacts because they do not produce these motion artifacts.
Additional Details: Panasonic plasma display panels are 12 bit, not 8 bit. The number of bits in a display panel determines the number of grey levels each colored sub-pixel (blue, red or green) can achieve. A Panasonic PDP can achieve 4096 gray levels per sub-pixel. These bits are NOT used to address the pixel and do not affect the number of sub-fields.
Sub-fields allow plasma manufacturers to reduce the cost of a Plasma TV. Plasma pixels are driven by large, powerful transistors to 300 volts. To reduce the cost of manufacturing and repair, plasma manufactures reduce the number of these drivers via multiplexing and sub-fields. The drivers are first used to address all the pixels in the first sub-field and flash image on this sub-field. While the pixels are decaying to black in the first sub-field, the same drivers are now used in the next sub-field to flash its image via multiplexers. This process repeats until all pixels in all the sub-fields have been driven to flash an image. The whole sequence is then repeated 60 times a second.
