working configuration of catalyst server, need tip

[faceoff]

datapath do that it 4output works on 50Hz or 60Hz multiply to input 4k@25Hz or 4k@30Hz. Nad of corse I switch on catalyst software playback from 25fps to 30fps and back.
My old one cat is: 2*4core xeon 12Gb ram GTX285 with 1 GB vram SSD 128Gb and HDD 1Tb. How crushes or whatever depends from output refresh rates and resolution? Or you trying to say me that D700 cannot handle 4k+2,5K resolution?

I had experience with same refresh rate at second output (if you means that 2 output must be at same refresh rate): its only affect on a new mac pro (on old one same load stable at any combination of refresh rate):
monitor datapath in load
2.5k@60 4k@30 8-50% (various)
2.5k@60 4k@25 10-30-60-90~100% (spasmodically)
2.5k@60 fHD@50 10-40% (various)
2.5k@60 fHD@60 8-40% (various)
fHD@50 4k@25 3-5%
fHD@60 4k@30 3-5%

So GTX285 better work than D700 , and this problem only appear on cat software (and no drop frame, all video playback at 25fps and 30fps stably) strange effect. Now I going to try datapath in 30Hz out 50Hz :/

trying to unpick this…. you mixing up loads of things in one go… you got to be careful with this stuff

one thing at a time:

what outputs you do on gtx285? 4k? 2.5K? what screen sizes and refresh rates?

[faceoff]

on GTX285 same things as on D700, both 2.5k@60Hz and second had 4k@25Hz (and it work normally), I update previous post , for now I am testing with multiply outputs 30Hz + 60Hz from d700 with output on datapath at 50Hz

we believe from testing that the new mac pro do not like mixed up refresh rates -

that does not mean gtx 285 is better -

it means different setups require different considerations to make them work correctly-

new mac pro might require - exact same refresh rates for best performance - and that means checking EDID from monitors

you know which physical display outputs you connected monitors to?
you aware of the physical ordering of the thunderbolt busses?

ofc I put a link at few thread below. I finish for today, but now I got headache with my job I need to take big resolution 'cause I have many layers and presets, and its possible with 60Hz. But all camera work on 50Hz shutter and 50Hz current frequency. I am going to sleep...

50Hz- you got to make everything work at exactly that?

you need 50Hz outputs- in europe - everything needs to be 25/50

thats why we are testing 6 outputs at dvi 1080p50 from new mac pro- n541 build
all exact same refresh rate -

no datapath - all monitors exactly the same- you need active mini display port adaptors to dvi - unpowered - to do this

if you need 25/50 -
you should try this option

lots of monitors don't support EDID for 1080p50 - i have lots of monitors that don't - i have to replace them with ones that do
we had another recent thread about the correct EDID to do this-
