@Bilkowrote: ps,,,My ? is for the Rogers signal only, is 1080 progressive necessarily better than interlaced, or is Rogers even sending 1080p ? pss..Everything else 4K UHD HDR with this TV is fantastic!!!
1. There is nothing broadcast natively in 1080p.
2. If I'm not mistaken, the 4642 can only handle 1080i, while the 9 series has the ability to upscale to 1080p.
3. Your BEST option of the UDH tv is to get a 4k receiver. The next best is the 9 series you already have.
