I noticed there are 8 HBaseT outputs in the back, but also it appears there are 8 HDMI outputs for each HDBaseT. Does this mean each pair of HDBaseT/HDMI output can result in a mirror image? Thus being a 8x16?

To be even more technical, it is an 8x8x2 (wherein each HDBaseT output has a cloned HDMI output).

Does this downscale? Ultimately 1 source in 4k going to a 4k TV and a 1080P provide a clear image on both displays? I have it narrowed down to this Matrix and another that states it does Downscale in the description.

BEST ANSWER: It doesn't appear to. I started a 4k stream on my Fire TV that played fine on a 4k but wouldn't play on an old 1080p Samsung. The web UI doesn't give any options for up/down converting the video format, but you can impersonate an EDID to force the source into different formats.

No, however you can add a downscaler prior to the display that is 4K HDR compatible. Monoprice 30460 would potentially work, or the RTI VDS-1x.

I'm working with pre-installed CAT-5, will that work with this matrix? would only be running 1080p @60

BEST ANSWER: I installed this over pre-installed Cat-5e to upgrade to HDMI from RGB. Longest run was most likely 80-100ft or less. I didn't run into any issues with it working correctly at these fairly short distances.

We would only recommend using a direct connection from the matrix to your display or devices.
The more connections you add to your setup the less likely it is that everything will work and work properly.

How do the remote displays work?

BEST ANSWER: Thank you for your question.
If you are referring to the displays the receiver would connect to they would simply use the HDMI port that is on the receiver boxes to receive video and sound.

Is the switching seamless? By that I mean when you change inputs does the output dropout temporarily causing the display to go blue (searching for signal). I was thinking about using this in a church setting.

I notice that the specs say:

Does that mean that you can only get 4:4:4 resolution with HDMI cables over a short distance?

How do the analog audio outs work - does the corresponding HDMI output need to be connected to an actual display for analog audio out to work? Will the matrix decode Dolby/DTS/TrueHD/Master Audio input formats for analog audio out? If the input is multi-channel (5.1+, PCM/Dolby/DTS/TrueHD/Master Audio) will the matrix mix it down to stereo, or just discard all but the L/R channels?

Monoprice Blackbird 4K 18Gbps HDBaseT 8x8 HDMI Matrix Extender Switch over Cat6 with 8 Receivers and 8 IR Kits, 70m, HDR, HDCP2.2, PoC, GUI and De-Embedded Audio: Product # 27842.
1a. do the audio outs mirror the Cat6 outs
1b. IF the audio outputs mirror the Cat6 outputs, will both still output full audio?
2. I take it there is no ARC function. Are you planning to include ARC in your next edition
3. I take it there is no App to control it on Apple or Android. Are you planning this for the next version?
4. Are the components used for the IR system the same as on previous Monoprice Matrix, e.g., the 1x8
5. Can I use the receivers I have from my 1 x 8 Monoprice Matrix, at the "far" end of the Cat6 run.
6. My outputs go to 8 TVs around the house. They all control the same 7 devices from the "ALL" IR output on the main unit (i.e., 3 receivers, cable box, PS4, DVD, VHS,
7 ). MOST IMPORTANT: How do you suggest splitting the IR signal from the "ALL" out at the back of the main unit, so that there are 7 IR emitters? I have tried to do this with a Niles IR block splitter but it doesn't work.

Ive installed this matrix and everything seems to work just fine. I used it to replace an Atlona (1080p) matrix. The description didnt mention that this matrix has downscaling so I ordered 2 separate downscalers for TVs without 4K support. I returned them once I found the feature was built in. Theres only one feature I miss from the Atlona unit. The Blackbird requires 3 IR commands (input, output, enter) to switch sources. This required programming a 3 button sequence in each universal controller at the destinations in order to switch sources. The Atlona matrix only required a single source IR command (since the matrix knew which destination was sending it). Overall, Im very pleased with the Blackbird. The extra audio outputs greatly simplified the use of my theater sound unit in my den. It also solved a problem I previously had with occasional blackouts from my most distant destination.

I want to give it a 5 start bc how cool the POE modulators are and the functionality of 8 in 16 out via Ethernet and HDMI but this thing caused me some pain all because Monoprice for some reason doesnt put the user manual in the profuct box sometimes and this cause an issue bc of how the EDID works on this switch. I am running 7 4k TVs and one 1080p projector for a church. If I would have know up front that the switch reads the EDID from the first output device which was a 4k TV it outputs the same EDID info for the remaining outputs which cause some issue in length. We ere playing a 1080p video pn all displays wondering why our lengths of 140 to 160ft werent working and the device says up to 230ft for 1080p but not knowing thr switch was outputting a 4k signal bc of the way it outputs the EDID cause us a lot of worthless work of rerunning cables for shorter lengths. Teouble shooting why our projector had a no signal smh bc it was trying to read a 4k signal on a 1080p projector. Do Bet
