Only 4 stars because, unfortunately, little problems when a 1920 × 1080 pixels resolution is set to the PC (with 3 different. PC / laptop tried). Image must then be manually adjusted to the correct size on the LCD TV. At low resolutions no errors. The source is immediately detected and optimally adjusted. Top picture! Surf now from the comfort of the internet. And 720p movies simply look great. For 1080p / 1920 × 1080 but then another cable is needed.
Edit: Now I've found out that it was the Samsung LCD. You had to rename the HDMI input to "PC". Strangely, now everything is working properly ...
