Datapath output 4x1 - 6240x1080

[jaydeeshow]

Hi,

My next setup is considering 4 projectors for a 4x1 (6240x1080) composition.

The data path support its very slow in responding my emails.

It's not clear if I can program the edid with this resolution.

Secondly I need to extend the data path input for about 30 meters (100ft).

Please suggest me a reliable and professional device without breaking the bank.

Best,

Jo.

I'm assuming 1) your output will be four 1920x1080 projectors with two 480 pixel blend areas, correct and 2) you'll be using your Datapath in conjunction with Resolume, correct?

You can program your X4 to be 3840x2160 with 4 quarter screens @ 1920x1080 set to each quadrant which will be your four outputs . If you're using an X4, your input (the output from Resolume) will be limited to 30Hz but if you're using an fX4 you can use 60Hz. Either way you can output at 60Hz or 59.94Hz from the X4/fX4

In Resolume, you would create one 3840x2160 screen with four 1920x1080 slices then you'd position each slice on the output to match your X4 output assignment.

Rather than giving you a lengthy description of the process, here is a little visual aid to point you in the right direction:

Hopefully this is helpful.

As far as sending a 4K signal 30m, I always use Fiber Optic adapters but it's really expensive (~$2,500 per setup) so if you're on a budget,I would use HDBaseT with Cat6a cables. There are many HDBaseT setups available out there but I tend to use either Atlona or Gefen gear and you should expect to pay about ~$250 per setup.

Hi Oaktown,

first of all thank you to be always present helping people like me. Resolume should pay you!!!

Yes you've assumed correctly.

I will look into this video, but this is what I've already done. Even programming the edid on a landscape composition 6240x1080 my mac and PC were both seeing it as a 3840x2160.
So I guess to use my data path programming the edid as said, run a 100 footer 4K hdmi extender. I love gefen, kramer but they are expensive, and for now I can only wish a optical fiber. One day.

Let me ask you how would you run the show I'm producing:

I have:
4 projectors on a a backwall; composition 6240x1080 @60hz
2 projectors on a statue: composition 1200x1200 @60hz

Option A:
I have a macbook Pro GT force 750 and a data path that in total would be 6 projectors but I have to buy ,3 hdmi extenders, 1 for the data path (4K) and two regular hdmi extenders 1080 for the other 2 projectors.
Budget $500 for the 4K and and another $200 each for the other 2 extenders 1080.

Option B:
a PC with 2 Asus Strix Ge Force GTX 970 with a total of:
DVI Output : 2 x (DVI-I), 2 x (DVI-D)
HDMI Output : 2 x (HDMI 2.0)
Display Port : 2 x (Regular DP)
In this case I should leave the Pc Case on top of the truss securing it with straps, and run a KVM (I guess they are around ($400) to control and map the show.

Thank you for now.

Best regards,

Jo.

First, thank you for your kind words

A few comments on your post:

Take a look at this project I did in New York last year

Budget $500 for the 4K and and another $200 each for the other 2 extenders 1080.

I use the Gefen GTB-HDBT-POL-BLK which you can find on eBay for ~$250 new. These units will do 4K at up to 230ft with no loss or latency. I'm a huge fan of HDBaseT and use that on all my projects these days using Epson and Panasonic projectors (Panasonic calls it PJLink) that can take HDBaseT natively so I don't even need the receiver 90% of the time and it's rock solid!

...and run a KVM (I guess they are around ($400) to control and map the show.

I personally don't use KVM but I make my own! I use a Gefen GTB-HDBT-POL-BLK and a Gefen EXT-USB2.0-LR and run 2 Cat6a cables from the server to my work station where I set up a 27" LED HD monitor with keyboard and mouse. The USB adapater is USB2 but it's fast enough in most cases to upload clips quickly onto the server if needed.

4k at 60 fps - great!
Main question - is it compatible with Datapath FX4 Display port 1.2 4k at 60 fps?
Unfortunately, FX4 has only HDMI 1.4 input and is limited at 4k to 30FPS. Considering stuttering Resolume playback, cutting FPS in two is a bad idea.

Is it possible to test if this Gefen will carry Display Port Signal to FX4?

p/s Personally prefer SDI over HDBaseT - already have mixers, cameras and other video infrastructure. Still waiting for SMPTE to make final SDI 12G spec to connect distant FX4 at 4k with single SDI cable (Belden already has cables for this).

HDBaseT unit is HDMI not DisplayPort. I don't believe there is anything on the market yet to extend DisplayPort 4K60 (or more) over long distances.

As far as 30FPS vs 60FPS, it shouldn't make a difference to your audience so if you can get your comp stable at 29.97/30FPS you should be fine. I still use the Datapath X4 so I use 4K30 all the time and it looks great. I'd actually be more concerned with my comp being able to sustain a stable 29.97/30FPS than trying to output a 60FPS signal.

Don't get me wrong, I use SDI all the time but it's limited to broadcast resolution which is not very flexible in most cases. HDBaseT will work with any resolution whether you're working with SMPTE, computer or custom resolution. Most projectors these days are WXGA or WUXGA and you just can't get that with SDI so when I work on projects that involve broadcasting, I use SDI between my server(s) and the switchers but I prefer HDBaseT to send my signal to the projectors.

Thank you for all these information. Without having this kind of experience I will have plan A and plan B.
I'm planning to buy the Gefen you've mentioned and I've read good reviews overall.
I will buy the usb extender as well just to start and stop the show, and in case the client wants new visuals, because I will map in the middle of the floor plan and run it from the back of the booth (it's an exhibition).

1)Any recommendation on a specific brand for the CAT6a?
2)This show will require 70' but should I buy a CAT6a about 200'?
3)Which Hdmi (regular 1080) extender would you recommend? What do you think about: http://www.oceanmatrix.com/product.asp? ... -HDMI-CAT6

Originally the composition was 4160x720 @60hz, how can I try to see if works at 30/29.97?

Beside this composition I have to map a statue lying on a rock that measures a radius of 6 feet. I'm still debated to use 1 projector right on top 90 degree straight, or to use 2 projectors from the side (30 degree) blending a lot but covering blind spots.

Thank you for now and after the show I will share what I've learned. Thank you!

Hey Oaktown,

I've looked into a usb extender it's CAD $ 600

I can't spend this money for this...
This will be for my plan B with the PC, because Plan A I will use the Macbook with the FX4.

Will a wireless system work? I can get around 8/10 meters from the Pc.

Thanks,

Jo

1)Any recommendation on a specific brand for the CAT6a?

I use Cable Matters Cat6a Snagless Shielded (SSTP/SFTP)

2)This show will require 70' but should I buy a CAT6a about 200'?

We have a few 200ft cables in stock but I personally prefer handling 100ft.

3)Which Hdmi (regular 1080) extender would you recommend? What do you think about: http://www.oceanmatrix.com/product.asp? ... -HDMI-CAT6

Don't know that brand/model but it seems that it only supports 480i@60Hz, 480p@60Hz, 576i@50Hz, 576p@50Hz, 720p@50/60Hz, 1080i@50/60Hz, 1080p@50/60Hz so for just a little more I would get two BMD Micro Converters (HDMI>SDI and SDI>HDMI).

Or if you have enough left in your budget, get another Gefen HDBaseT unit.

Originally the composition was 4160x720 @60hz, how can I try to see if works at 30/29.97?

Set your Datapath and projectors to 30/29.97 and your comp will default to 30FPS.

Good morning,

after your advice I've inquired my retails shop to find something for me and this is what they found.
What do you think about this unit:
Atlona: 4K/UHD HDMI Over HDBaseT TX/RX Kit

compared to the Gefen you've recommended it looks like support 4K at 50/60Hz.

Am I correct? Anyway you suggested me Atlona, so I'm pretty sure it's reliable.

For the cables at this I'll buy 3 x 100feet. In the future in case I need a longer length can I hook them one to the other?

Best,

Jo.
