R rituj26 Honorable Sep 12, 2013 5 0 10,510 Sep 17, 2013 #1 I have an Philips HTS5520. It has an HDMI upscalar also but when i play some movies with a resolution of 1280*720, it says that resolution not supported. Why does this happen?? And what are the appropriate resolutions which i can play on it??
