60HZ is the default windows refresh rate... u probably havnt set it up correctly to match your screen.
do u know for certain incoming tv runs at 60Hz from the broadcaster coz that doesnt sound right. UK should be either 50hz or 23hz (23.976).
open device manager in windows and find ur monitor.. make sure the refresh rate is set corretly there before opening MP.
Next the cuvid hardware deinterlacing (nvidia card users) . Open the MP Config shortcut on your desktop(or in start menu). find Codecs and Renderers in the list, go to video codecs ..select LAV video. next to it is a small button to open its properties page.. set hardware deinterlacing option there and...
I changed my main monitor to 50Hz, the other one won't let me change, but I don't use that for TV. ( If it was a case of the monitor Hz then why would it run perfectly fine on HD signals? surely it would lag on both if it was a streaming Hz )
There is no little button next to it. The only clickable thing is the arrow to open up the list!
Also can you help me get the TV running again? No idea how to restart the stream.
