Got my 5040 a couple days ago and I can't believe the difference it makes. I'm coming from a 5010 which I thought was very good. The 4k enhancement on 1080p is no joke! I don't have a 4k player yet but did get the Roku Premier+ and the 4k streaming on Youtube is incredible. I understand the issues everyone is talking about with HDR though.
I've run into a weird problem though and Epson support has said they haven't heard of this one yet so they will research and get back to me. Here's the issue:.
When I was watching 4k streaming on Youtube I was playing around with the HDR modes and color space and found a combination that was OK. Not great, but okay. I decided to save a memory slot with those settings for 4k streaming. When I switched back Blu-ray input which is PS4 everything was fine but then I tried to load my original memory setting for Blu-ray and the screen went blank. The projector was still in, iris closed down quite a bit but remote was unresponsive as was controls on PJ. Blue power light was on, couldn't really hear much noise coming from PJ but wouldn't power off. So I had to unplug.
After about 10 min I powered it back on. When I was messing around trying to get a response from the PJ I switch input on AVR (Denon x4200w) to DirecTV, so that's what came up when I powered the PJ back up. The color space and HDR modes was still active, so I tried again to use the original memory that I have set for Blu-ray (Dynamic Range and Color Space both set to Auto). PJ froze again.
Powered back up but had AVR source set to PS4. Manually changed the settings to Auto, re-saved the memory. Added a new memory with random changes to settings. Flip back between those memory settings and everything is fine. Go back to Roku>Youtube and manually change settings. Everything is fine. Switch back to PS4, manually change, everything fine. Then toggle memories with "Auto" for HDR and Color Space, everything changes fine. Toggle back to memory that I saved when first doing streaming 4K on Roku (while in PS4 input), freezes again.
Anyone experiencing this? Like I said Epson had no clue, just asked what FW I was on which is 1.05 ( I think). It say 105 for Main and 103 for Video 2, whatever that is.
So for now, when wanting to change settings after switching between a 4k source and 1080p source I guess I will have to change the Color Space and HDR manually. Very strange.
