working configuration of catalyst server, need tip

[faceoff]

It's my datapath at home, that going from work where I must send Full HD 60HZ, at work another one it 3840*2160 @ 25hz and NEC PA272B is my working screen with presets etc (at work I got 30 inch HP with 2560*1600 also 60HZ). And why its not compatible if they multiples of each other.

All worked perfectly with my old one catalyst server based on 10.6.8 with gtx285 with the same resolution with crushes but it will be about 1-2 time in a few month. So I think output resolution is not a cause of crushes and can't load my video cards for 100%.

full HD 60Hz output? 1080p60?
datapath doesnt do that-
you using dathpath to convert 30Hz to 60Hz?


what did you do with gtx 285? - exact config

[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

[samsc]

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...

[samsc]

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-
