4K on dual stream Display Port

Recommended Posts

Dear All,

 

we're looking for using Watchout to drive a 4K projector. this projector requires dual stream of Display Port 1.1 to make 4K resolutions on 2 x 2048x2160 side by side. we understand nVidia Quadro K2000 can do 4K on Multi-Stream Transport(MST).

 

I just wonder if you've tested this graphic card before?  

 

we can also have AMD FirePro W5000 2 x Display Port, which one is recommended?

 

Best Regards,

Hashem

Dear All,

 

we're looking for using Watchout to drive a 4K projector. this projector requires dual stream of Display Port 1.1 to make 4K resolutions on 2 x 2048x2160 side by side.

 

I've never seen this before, what projector is this? 

 

Why not the normal way, to me, ie DisplayPort 1.2/1.2a or HDMI 1.4 direct, as one signal?

 

WATCHOUT has no problem to drive one or more 4K outputs, it's more of a hardware question,

and not only the graphics card. All hardware components in the system needs to be up to

the task of 4K playback. Choice of codec/bitrates comes in to play here, too.

 

Do you mean 4K as in 4K 4096x2160 or as UHD 3840x2160?

 

 

we understand nVidia Quadro K2000 can do 4K on Multi-Stream Transport(MST).

 

Maybe, but it can for sure do 4K on a DisplayPort 1.2 output, as one signal.

If it's a good match for other, more demanding WATCHOUT tasks, I don't know.

NVidia Quadro K2000 is also rather old now, replaced by K2200

 

 

I just wonder if you've tested this graphic card before?  

 

No, we have not.

We usually recommend higher end cards for WATCHOUT use, like the NVidia Quadro K5200/K4200 or AMD FirePro W7100

I would say neither.

AMD FirePro W5000 is also rather old, being replaced by W5100.

That would be the better choice, I think.

Hi Jonas,

 

Projector is Barco HDQ 4K35 and by 4K I mean 4096x2160.... currently I have a demo projector and there I just have DP 1.1 so I can't have single stream DP 1.2

 

from the local market I could find nVidia K2000 and AMD FirePro W5000... I'll try to see if I can find more recent card which you mentioned but in case I couldn't, which of thosa cards would you recommend that I go for? nVidia K2000 or AMD FirePro W5000?

I'm not sure about actual Workstation resources but it is a good HP workstation as we can drive 4xHD@120Hz with no problem.

 

regarding content we're preparing a WO show out of still high resolution pictures. we have some 4K videos too but I'm not sure what is their spec but we don't have any restrictions on video part. all we care is that it should be uncompressed 4K video. can you recommend any online store which we can download/buy videos that you know are compatible with WO?

I don't think one does uncompressed 4K video on just any Display PC.

This will need some serious hardware.

No, I can't recommend, but others can probably chime in here.

Are you not creating the content?

 

WATCHOUT accept/plays many fileformats, most common for 4K

is h264. If you have the necessary hardware resources, then

ProRes at 4K is possible. Still not uncompressed, though.

Framerate at 23.976/25/29.97/30 is less demanding than 50/59.95/60, of course

video resolution is 4096 x 2160. 

 

one more question... we drive this projector with two x Display Port each for half of the 4K to reach full 4K resolution. on nVidia we setup 2x1 Mosaic so windows sees one display in 4K resolution. my question is how watchout would treat it? does it see two display or one? if WO sees two display, then is there any option in WO to bind these two together so we can apply warping on these two as if they are one display?

We have not tested this, since we don't have a Display needing this kind of  setup..

Normally neither Mosaic (NVidia) nor Eyefinity groups (AMD) is used for a WATCHOUT multioutput setup.

 

I would guess WATCHOUT sees what Windows sees, one Display.

 

Have you not tried??

No, there is not.
