In an announcement, Youtube said it will start supporting High Definition 1080pixel videos. From the present maximum resolution support of 720pixel, Youtube, starting next week, will provide necessary support for viewing high definition resolution in the range 720p to 1080p depending on the source resolution capability.
It is great news for me and scores of other users who will enjoy this facility in their living room. I have a 50 inch TV of LG BD390 model with Blu-ray player. However, the SD Youtube videos operate on full screen mode on TVs with Big screen.
