It's not a PC but as you know, folk want the PC experience and capability.
1. My old LG DVD player connected thru HDMI, picture on screen but no sound.
2. Plug in win 7 HP laptop thru HDMI, no picture and sound all even I have toggle to monitor.
3. Run out of memory when surfing Internet, suddenly exit. This happened Even while surfing the built in youtube apps.
I don't have such problem in part 1 and 2 when I am using my old Philips LCD tv. So Samsung not so smart after all!
Anyone can help
