This is my first post. Hi to all! We have 11 projectors 1920x1200 60Hz and we need to show 11 diferents videos. One per projector. The display clusters are 2 computer with 6 outputs. The hardware specifications are: i7-5930K CPU 3,5Ghz (6 cores) with Corsair Hydro H60 16GB RAM Kingston HyperX Predator DDR4 4x4GB 2133Mhz Main board Asus X99-Pro Graphic Card: Sapphire FirePro W9100 (FireGL V) HDD SSD SAMSUNG EVO 250GB (MZ-75E250) HDD 1TB ST1000DM03 Power supply Tuniq 950W 80+ Windows 7 64bits Watchout 6 All outputs from FirePro are forced edid to 1920x1200 60p. The resolutions of the each video are: Projector10 (Out 1 Cluster1): 1766x1200px (video10) Projector11 (Out 2 Cluster1): 1248x1200px (video11) Projector1 (Out 3 Cluster1): 1508x1200px (video1) Projector2 (Out 4 Cluster1): 824x1200px (video2) Projector3 (Out 5 Cluster1): 1270x1200px (video3) Projector4 (Out 6 Cluster1): 864x1200px (video4) Projector5 (Out 1 Cluster2): 1564x1200px (video5) Projector6 (Out 2 Cluster2): 1244x1200px (video6) Projector7 (Out 3 Cluster2): 1720x1200px (video7) Projector8 (Out 4 Cluster2): 860x1200px (video8) Projector9 (Out 5 Cluster2): 1858x1200px (video9) The problem is that the display clusters are not able to play all videos smoothly. We are codec the videos in some formats. 25Fps/30fps; 4:2:0/4:2:2; baudrates of 2Mbps,5Mbps, 15Mbps; in mpeg2/mp4/h264 but it can't play six videos per cluster. We are only able to play 3 or 4 videos ok. For example: mpeg2 30fps 4:2:0 5Mbps the cluster1 is be able to play smoothly video10, 2, 3 & 4 on it's projector. If we show the video10 on projector11 & 1, the system play smoothly too. If I change the video of projector 1 from video10 to video1; the cluster1 not play smoothly. The videos are playing with breaks. At the same conditions the cluster2 is be able to play smoothly video5 on projector5, video8 on projector 8 and video 9 on proyector 5, 6 ,7 & 9. Anybody can help us. What's is the problem? Any suggestion? Thanks in advance.
