Alright, had the splitter about two days. Call me superstitious, but I was concerned it would effect input lag, but I haven't noticed any difference in a few hours of Battlefield 1.

I can't seem to get the HDMI-CEC to work anymore, but really I wasn't hopeful. (I flipped HDMI-CEC on/off and now tv doesn't seem to receive it for either input. That's ok; I think it's asking a lot of a $20 splitter to detect current input and intelligently route HDMI-CEC there.)

I did have to enable HDR on the tv for both inputs in tv config in order to get HDR on just one input. But once I did the HDR comes on.

The Samsung likes to auto-detect and rename my input labels, so I've given up trying to rename them things like "PSHDR" and "PS."

Overall, does what I hoped it would and no surprising adverse effects. This is the one I got, BTW: https://www.amazon.com/gp/product/B00F5R9TNM/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

You can try an hdmi splitter but copyright laws may prevent you from multiplying the signal. That's why bars spend thousands on equipment because each tv needs its own receiver.

My recommendation:

Although this is your best bet there is still a chance of copyright signaling preventing the duplication of a second signal.

Yes. You can split HDMI to multiple screens. But all the screens have the exact same content. I split my cable boxes HDMI out to multiple screens and my PC's HDMI output to 2 screens too.

I bought a powered "1x2 HDMI splitter" on amazon. https://www.amazon.com/gp/aw/d/B00F5R9TNM/ref=mp_s_a_1_7?ie=UTF8&qid=1483642867&sr=8-7&pi=AC_SX236_SY340_QL65&keywords=1x2+hdmi+splitter&dpPl=1&dpID=41WFEFz%2BVwL&ref=plSrch

SmallHD claims their splitter works without needing a 5v tap:

I usually recommend a powered splitter, which the above can provide as well (and some are cheaper on amazon), but then you would obviously need to tap that in from somewhere.

If you want it to show the same on both external screens you can use one HDMI to an HDMI 1x2 Splitter.

This is an inexpensive splitter that will solve your issue. You can get cheaper ones, but this one is powered and will prevent any signal loss from splitting one hdmi signal into two.

With the HD60 Pro I downloaded the Elgato software just so the drivers were for sure installed. When it came to using a PS4, I had to disable HDCP on the system for it to work perfectly. But because a PS3 has permanent HDCP, you have to use a splitter to strip away the HDCP. This is the splitter I have. So I'm using 3 HDMI cables: (1) PS3 to Splitter Input, (2) Splitter Output 1 to Elgato, and (3) Splitter Output 2 to Monitor. It is finicky, but there's no issues recording or streaming.

Thanks for subscribing btw! I'm recording Nier on my channel right now, which is using this exact setup.

Don't have a ps3, but i went and enabled HDCP on ps4 and captured just fine. This is the one i bought.

I'd recommend you get an HDMI splitter like this one. Connect the input to your console, and use another two cables to connect the outputs to your display and to any capture device of your choosing. I wouldn't recommend using video capture software on your computer to see your gameplay, it adds a noticeable amount of lag most of the time.

As for HDMI capture that supports Linux, BlackMagic has official support for Linux, but I hear their actual customer support for their hardware products is quite poor, and I haven't tried them myself. I currently have a Hauppauge Colossus, which has no support for Linux (unless you're a company looking to pay these guys for bulk licensing) and is limited to 1080p30 at most. So, I recently ordered this, but I haven't got it yet. I'll let you know if it works well.

You need a splitter like this

Yep....I gave you a link to a cheap one that takes care of the hdcp protection and is 4k compatible.

Also, I'm pretty sure the digital optical DOES support 7.1 through Dolby bitstream... but the HDMI definitely does carry 7.1 uncompressed

I'm using a Slingbox 500 with my Spectrum cable box (HDMI only) and I can confirm that this HDMI strips HDCP, allowing you to stream via HDMI from your Slingbox.

If you're only steaming cable, I wouldn't worry about HDMI 2.0. We're not taking 10-bit HDR, 4k, or high-frame rate content, but rather super compressed cable at max 1080i60.

If you need to use a splitter though, this one will do 4k:

You are probably using too long cables for a passive splitter (the two you linked). How long are the cables? Even regular HDMI cables have issues if too long.

An active HDMI splitter (which has a power input to amplify the signal) would probably do what you need. This one has good reviews: https://smile.amazon.com/HD-102-Powered-Splitter-Certified-Support/dp/B00F5R9TNM/ref=sr_1_8?s=electronics&ie=UTF8&qid=1486654568&sr=1-8&keywords=hdmi%2Bsplitter&th=1


edit: though I would probably just do what SJC856 recommends (if you computer has multiple video outputs)

Thank you for the response! I was talking with a few other people and the predictions were:
> My TV guy at work said it could be EDID differences and if the TV isnt the same native resolution as the monitor it won't mirror properly.. because it can't. That's why it would only have an issue after the splitter is added to the chain. Are they different native resolutions?

> The computer may use drivers to support the output to that monitor and when it's plugged into the splitter it is no longer receiving driver support.

I contacted the company OREI and they said:
> Thank you for contacting us. You'll have this issue with the HD-102 when you are connecting two different display types (TV and Monitor). You won't have this issue if both are monitors or both are TV. In this case, we recommend the OREI HDS-102 which supports EDID selection.

So now my question is which of these issues is it actually?

OREI believes that if I return the splitter I have HD-102 and get HDS-102 that my problem will be solved. Any other opinions?
