Hola.
Como ya he puesto en otro hilo
Información:
The TX-NR636 is one of the only A/V receivers to feature the latest HDMI supporting 4K/60 Hz and 21:9 display format and HDCP 2.2 copy-protection compatibility. Qdeo™ upscaling technology also converts low-res DVDs and games into pin-sharp Full HD or 4K (if you have an Ultra HD display). TX-NR636 paves the way for Ultra HD video playback at a liquid-smooth 60 frames per second. This is great news for PC gamers who can now add wall-shaking surround sound to their 4K/60 Hz experience.
