Mixed 4k and 1080 displays...does it work?



Does anyone have experience with a system that has some 4K displays and other 1080 displays and how it works with say Apple TV 4K or DISH that can display either resolution? Do the sources bounce back and forth between resolution depending on the display or do you have to set it and forget it (all or nothing), especially with something like a Leaf HDMI matrix in the mix?

maybe mo ip fits your needs.

pro: you can scale the resolution to each output device.
con: most devices only go for 4k30hz instead of 18gbit hdmi

Got a scenario where only one device can´t handle 18gbit hdmi.
So i reduced the output resolution from 4k60hz 4:4:4 to 4k30hz with a hdfury scaler
hdmi 18gbit matrix in background for video distribution

To answer your question, no the sources do not change resolutions.  In typical boxed HDMI matrices, the sources EDID will only allow Up to the lowest common denominator, aka 1080p.

The easiest solution for this Is to purchase 4K up/down scalers.  Usually nowadays there’s more 4K TVs than 1080 so the cost isn’t too bad.  But if it’s the other way around, may be better off getting local sources for the 4K displays.
