I recently replaced my old 3d Panasonic Plasma TV with a TCL Class 5 series QLED. I'm currently using the same AV receiver HT-R540 with 5.1 Definitive tech Speaker setup. I have noticed when playing Dolby Vision or 4k content the surround sound is so much better especially on Neural Surround. Is the old HT-R540 taking advantage of the Dolby Atmos movie content? And if I upgrade my AV receiver to one with Dolby Atmos using the same speaker configuration would there be any significant improvement?
