hey antinoitikos , thanks for the reply. I have been traveling this week so I am just back to troubleshooting but I do believe I have discovered an issue and maybe the primary issue. This is what I see when watching through Output 2 and my Apple TV 4K on a Dolby Vision enabled movie like "The Fifth Element": And this is what I see if I hook up Output 1 to the TV with the picture downscaled: Which explains why the colors work but they are always Red and Purple. I also noticed that like another person in this thread, I also have a stuck hardware button on the front of the device. I flashed the chip and Factory Reset several times but the issue persists. I believe I have a faulty Matrix unit. I sent an email to support to see what they have to say. That would definitely explain the issues you’re having. If you purchased the unit from Amazon, don’t forget you can always use them first for expedited resolutions. If the item is still within its return period, Amazon will send you a replacement if you state the current one is defective. Either way, let me know how it turns out! After a year of battling with technical issues (if your experience was anything like mine with the DS4K), you’re almost there! Thanks antinoitikos. Just to confirm, you can run Dolby Vision content to a Dolby Vision capable Input from Output 2 while running the same Dolby Vision content downscaled from Output 1 to a 1080p display and it looks normal?

Here’s a video of DV content playing with the DS4K working in the background. I made sure to record from initialization to playback, in case ezcoo might ask for an example of it working.

So after a replacement unit and some more testing, I am convinced that this Matrix, while very useful and high quality, does not have the ability to properly downscale Dolby Vision (DV) content. Here is my setup for testing: Matrix - DIP Switch 1 - Off
- DIP Switch 2 - On
- DIP Switch 3 - Off (also tested on)
- DIP Switch 4 - Off (also tested on)
- Input 1 - Apple TV 4k
- Output A - HDMI 1 on LG OLED B7 (Operationally would be in HDMI 2 on DS4K)
- Output B - HDMI 2 on LG OLED B7
These are photos after hooking up the replacement unit and testing DV settings from the Apple TV This photo is with Dolby Vision turned on the Apple TV and HDMI 1 from the TV which is the 1080p downscaled content This photo is the same screen after changing to 4K HDR, still from HDMI 1 on the tv showing the downscaled 1080p content Now even with the Apple TV manually set to 4K HDR (or SDR for that matter) with the Matrix switches 3 and 4 set to off or on, the ATV Info bar will report Dolby Vision as seen in this photo. Meanwhile the LG is showing, what I believe to be, the correct information contradicting what the ATV is reporting Additionally, flipping DIP Switch 3 and 4 to ON forces my ATV4K to 4K HDR (or any lower resolution). The Dolby Vision option goes away completely as likely expected based on the Matrix EDID settings. Somewhat strangely, forcing this setting also causes a loss of Dolby Atmos and instead forces LPCM to the soundbar. I would certainly love some other people to validate what they are seeing with the same test but after hours of additional testing with a brand new unit, I am confident it can't downscale the DV content. Support says they are reviewing my case and notes and would let me know what they find.
EDIT: Support confirms this matrix is not capable of downscaling Dolby Vision contentFor the moment, I am just running the ATV in 4K HDR (without frame matching because otherwise it will force DV and cause the DS4K to show only red and purple colors in line with the first photo) and the DS4K is running beautifully and while the difference between DV content and HDR 4.2.2 content is probably marginal at best, it is still a little frustrating to consider the additional money spent and not getting the DV experience I was hoping for.

So it looks like Sony’s A1E OLEDs utilized another standard of Dolby Vision. This forces the hardware to do most of the work and then send a modified signal to the television. Phil Jones, Sony TV product management director, told HD Guru that when Sony delivered the Dolby Vision firmware update late last year, it used a new Beta profile of the Dolby Vision software, which requires any connected Dolby Vision supporting device to have the same profile version for the source device and display to communicate with one another.
“There are multiple profiles of Dolby Vision,” Jones explained. “Our new television sets are using the latest [Beta] profile and some of the Dolby Vision source devices that are available are going to require a firmware update to support the same profile in order to work with our televisions.” -HDGuru.com I may be wrong, but this might explain why my downscaling is working. Here is my Output A showing it’s in 1080P and Dolby Vision properly utilized on the ATV4K. I was hoping this could be the one to fix everyone’s issues, but unfortunately that super expensive and yet released Fury box may be the answer.

I am pretty frustrated by the whole thing but I also like working out challenging problems so there has been a little satisfaction. Now I have to decide whether to keep this Matrix, wait around for the Diva or Fury or whatever or just look for a cheaper version that doesn't support DV but still supports Atmos. The ATV4K is a great device but it drives me crazy that you can't manually bypass DV when running it at 4K SDR with Range ON. I guess I shouldn't be surprised because Apple knows best, certainly more than their customers. And I guess I should include LG for also not making their OS more user-customizable but as fragmented as HDR technology is already I guess they think that removing that layer helps the average consumer. Of course, most of us here aren't exactly average users lol. So as I see it, I can either run everything at 4K SDR or 4K HDR if I want to use DS4K and neither option is particularly appealing and going in and changing it every time I want to watch something in a different resolution is just a non-starter. It's awesome though that your Sony is compatible and you deserve it after the Yeomans level work you have done in this thread.

It's a bit disappointing but I knew that was going to case with what I know about DV. I think I'm going to order an HDFurry Diva at this point. I wish it was a cheaper to work around an issue that DS should have taken care of in their hardware. The Diva also has an ambient light option but unfortunately don't have a light kit for my TV size. Once they do I'll probably give it a try over the my DS for 4k. I can then put the DS back on my 1080p Plasma where it always worked perfectly.

Looks like this one doesn't downscale HDR. So unless you plan to do SDR only it won't work to downscaler HDR10 content.

So at this stage i have an AppleTV 4K -> Denon AVR-X2000 -> DS4K -> Panasonic VT30 (1080p) Plasma. The Dreamscreen works fine as long as i leave the AppleTV set to output at 60hz, however if i enable Frame matching, 24hz is pretty much a no go on the Dreamscreen lighting and 50hz is hit and miss (i'm in Australia). If i were to invest in one of the splitters suggested above would i be able to use Frame Matching flawlessly, or is that a pipedream?

Your content will play smoothly, but your LEDs will continuously flicker in and out.

Hello all, I know that many of you are experiencing issues with your DS 4K devices, trust me, I was one who had to deal with returning two models until the third worked. Due to the lack of news on the DreamScreen connect, I was debating on removing the DS4K entirely since it affected our Harmony remote experience and I was relying on the unreliable HDMI CEC switching feature in the app. Fortunately, I found an HDMI switcher that supports 4K/4:4:4/ Dolby Vision/HDR10, has two outputs, an SPDIF output to resolve audio lag issues, and an official Harmony remote device profile! HDMI Output 2 sends the full uncompressed data to the television, as long as you have the correct EDID switches enabled. What I did to resolve issues with the DS4K is limit HDMI Output 1 to downscale the output to 1080P only. Lo and behold, everything works now! Since the switch DOES NOT use auto switching, I can leave CEC turned on my TV so it properly turns on the DS4K using HDMI CEC power detect in the event it is sleeping. I can view my Dolby Vision content while still having my lights work due to the downscaling technology. Unfortunately this means I wasted money on a 4K model since the 1080P DreamScreen will be more than adequate for this setup. The fortunate part however, is that I now have my Dolby Vision content back!!!
Please note that out of the box Dolby Vision was not working for me. If this is the case, go to the website and download the firmware update tool. It immediately fixed it for me. If you’re uncomfortable updating it, I’ve heard their support team is really good and will send you an updated firmware box while you return the other one.EDIT: It looks as though I lucked out due to Sony using a different standard of Dolby Vision that most television makers don’t utilize. This allows my downscaling to work with DV turned on, but will most likely not be the case for others.You can find the EZCOO HDMI 2.0 Matrix 4x2 on Amazon: “https://www.amazon.com/dp/B078YS79HZ/ref=cm_sw_em_r_mt_dp_U_URvBCbR2AHGMP” Hi, I have a Nvidia Shield on my AVR and the AVR (Denon x2200w) is on my TV (OLED LG B7). Also my PS4 is on the AVR. On the 2nd outpout from the AVR is my DS4k SOLO. The Shield works fine with all. 4k, HD Sound, HDR, DS4k Solo Lights and so. But with the PS4 i have the following problem: dreamscreen.boards.net/thread/1696/signal-ds4k-solo-avr-ps4?page=1Please don't forget the YT video. Do you think somehow the HDMI splitter can help me for the PS4 problem? Thank you.

Andre, yes, it would probably fix your issue. I can't say for sure but I will say what it did for me.
I now have the HDMI Matrix as detailed here, the EZ-MX42PRO-HAS model (https://www.amazon.com/gp/product/B078YS79HZ/).
I don't have an HDMI AVR so I am using the matrix as a switch for my two sources (PS4 and PC) and the second 1080p output to the DS4K. I ended up having to use Premium Certified HDMI cables (in my case mrocioa ones from Amazon UK). Some of the HDMI cables I had before (including the one supplied with the DS4K) were not up to the job.
What I like about the matrix: - Fixes all the problems caused by the DS4K. I now have full PS4 4K/RGB/HDR support back and absolutely no flickers or dropouts. - I can switch inputs using my Harmony IR remote (which of course you can't do with the DS4K). - I can use the optical output from the matrix to my AVR so I get both Dolby Digital & DTS support from my sources whenever I need. Previously I was using the optical from my TV which only supported Dolby Digital OR DTS passthrough via a setting, not both whenever I wanted.
What I don't like: - The matrix does not support CEC commands which I was previously using to operate PS4 Netflix with a Harmony IR remote. Back to using the PS4 controller... - I do get a split second of audio "cracking" sound sometimes when sources start up or change from DD to DTS etc.

This one doesn't downscaler HDR10. But if you don't have an HDR tv it's a cheaper alternative.
