M329+FX4000 quadro problem

[fabiopagano]

tomorrow i try whit only one out on triple head whit displayport, if signal is good means that video card can't make 6 screen at 1280x1024 ,i can make 6 screens whit ge force 8800 and gtx 285 card ,maybe use two different tipe of triple head is not good idea .
thanks good night

I have done plenty (too many) shows with dual TH2G. They have all been on 2008 machines with 8800s. Just because I have done this does not mean I suggest this. In fact, I won't do it anymore.

In the 2009 or 2010 machines, I have not been successful in using 2 TH2G boxes, especially mixing 2 different types.

The best recommended configuration for a TH2G is to place it on the second Output and have a monitor or 4th out on the First Output.

I will also note that 1280x1024 is 5:4 ratio not 4:3. If your output devices are 5:4 then using the 1280x1024 is reasonable. Otherwise, stick with 1024x768 unless you absolutely need the resolution. Then only use a 5:4 if your projectors are 5:4 otherwise, you'll need to use the Matrox Desktop to enable 1280x960 which is 4:3.

i think there is a maximum limit which the graphics card will do
and
i think there are some things with display port bandwidth and how this works - how many output lanes are in use

there has possibly been some architecture change to recent graphics cards which puts a lower limit on output sizes

DisplayPort is capable of directly emitting single-link HDMI and DVI signals using Dual-mode DisplayPort. VESA has issued interoperability guidelines for supporting single-link DVI and HDMI through a DisplayPort connection using a relatively simple passive adapter that adjusts for the lower voltages required by DisplayPort.[15][16] Dual-mode DisplayPort chipset detects the DVI or HDMI passive adapter and switches to DVI/HDMI mode which uses the 4-lane main DisplayPort link and AUX channel link to transmit 3 TMDS signals plus a Clock signal and Display Data Channel data/clock from the chipset. Dual-mode compatible ports are marked with the DP++ logo; most current DisplayPort graphics cards and monitors support this mode.[4]
A notable limitation is that dual-mode can only transmit single-link DVI/HDMI, as the number of pins in the DisplayPort connector is insufficient for dual-link connections and an active converter is needed for Dual-Link DVI (and analog component video such as VGA); however, VESA foresees that all HDMI conversion will eventually be handled by active adapters which act as DisplayPort Sink devices, in order to facilitate easier updates to latest HDMI specs and support multiple streams, dual-link HDMI,[4] or DisplayPort connection with fewer than 4 lanes, as in PDMI. DVI 1.0 spec was finalized in 1999 and the DVI industry consortium has since disbanded, which means future updates to DVI specification are unlikely; also, although dual-link HDMI Type B is defined in the HDMI specification, it has not seen any practical use so far

Also with only one triple head Displayport same defect, When catalyst go in full screen mode black screen (no video input) I need 6 out at 1280x1024 to drive a 6 mm pitch LED screen measuring 3360x1360 total resolution size mix 1120x680 x 6
some ideas for fix this ?thanks to all

is this for the display port model or the other one?
this means you are doing something the triple head and graphics card dont want to do

-

what refresh rate are you set to?

[fabiopagano]

refresh rate is 60 hz resolution is 3840x1024,3072x768, same defect, triple head display port on out one of quadro 4000 (display port )

and the other output? the dvi output?
does that work at this resolution?

--

start at the lowest possible output size and work up
dont start at highest size and work down

...I need 6 out at 1280x1024 to drive a 6 mm pitch LED screen measuring 3360x1360 total resolution size mix 1120x680 x 6...

If I understand you correctly, you have 6 processors feeding 6 walls that are configured in a 3x2 arrangement...

I just created a test piece of content 3360x1360. I used my 2010 12-core mac pro running Catalyst with 2 RAID0 SSDs outputing on a quatro 4800.

I was only able to run 1 layer of content without frames dropping.

I did however split the piece into two pieces at half size (3360x680) and was able to run them both in perfect sync on 2 2008 mac pros.

If you do the same thing then you'll be fine.

Oh and please share more about the wall. I am impressed by a wall that is 20x8 meters at that high a that resolution.

what works and doesnt is a thing between matrox and graphics cards

and apple and graphics card -
