I can confirm that a firmware update increases the PWM-frequency to 480 Hz
Before the firmware update I took this image
The exposure time was 1/13 s and you can count 9 lines, which means a PWM-frequency of 13*9 Hz = 117 Hz
After the firmware update I took this image
The exposure time was...
I have my 43UD79-B since a few days. All in all I am very satisfied. But I have a strange issue.
In very rare cases I can observe some horizontal pixel errors. Have a look at the following photo:
I figured out that these errors have something to do with the overdrive (response time) setting...
