I'm using Skype by many years because was one of the most easy application to use for video call with family and friends, but later this year I have upgraded my dad PC with a new HD webcam (Logitech c920) with the hope to get a better quality from home. After few visual test I have realised the quality is not as expected, start to made more videocall test with some friends from another city what i know the have an HD camera and as well no HD quality. Want to say my home pc(dad pc) have a good CPU i5 quad core sandy bridge, with 8GB ram, ssd, internet speed 300Mbps, all drivers installed and still nothing the largest resolution I got is 960x540. Always the quality is on medium, the ping between me and my friend from another city is by 5ms our speedtest between us is by ~250Mbps, he have as well a good pc. In the end we give up of trying to made this to send HD quality.
