I upgrade my Yamaha RX-A1040 to a RX-A2080 so I could have Dolby Atmos. However, now I find out that there is very little Atmos content for 1080P systems. It seems to get Dolby Atmos I need a 4K Blu-ray player. Since my 1080P projector is only about 2 years old I'm not about to replace it. So I was wondering, can I buy a 4k Blu-ray player and play the disc's on my 1080P system and get the benefits of Dolby Atmos sound? Is it worth it until I finally upgrade the projector to 4K or 8K? Will the Blu-ray player play nice with the 1080P projector? Thanks in advance for your responses.
