Jinja Posted June 29, 2012 Posted June 29, 2012 I really am partial to Eyefinity 2x1 builds because of the cost of entry is much lower than a triple-head setup. Hi Brian, Fantastic photos... Helps visualize potential setups for me. Ive Long term serious plans for a multi pirojector setup.. Currently flooring my attic in prep. Always assumed I'd have to go 3 x 1 set up because otherwise the hud would cross the join of a 2x1 setup. Can you dial in the join so well that its not an issue.?.. If so, fantastic. Id be more than happy with the field of view in those pictures you showed, and im going to save money in projector and gpu too... i7@3.5Ghz, ATI 5870, 16GB RAM, win7 64bit, TH2GO, Track-IR, 4screen pit, TM WArthog HOTAS
BHawthorne Posted June 29, 2012 Posted June 29, 2012 (edited) Actually Brad, not Brian. Yes, you can blend 2x1 just fine. If it goes out of calibration you'll know it though. I'm picky with my setups regardless of 3x1 or 2x1 though and like to maintain good calibration while in use. Just be mindful that the more rigid your projector mounts the less problematic routine calibration will be. My first setup had cheap Monoprice mounts and the projectors were mounted in the basement right under the kitchen. People would walk through the kitchen and after a few days my alignment would be off 4-5 pixels. Fixing calibration is only a one minute thing, but it gets annoying if you have to do it every few days. With a rigid mount you'll minimize calibration issues though. With you mounting in an attic, at least you're not mounting on a ceiling that has people walking upstairs on. :) Be mindful that 2x1 configuration is primarily an AMD Eyefinity exclusive. NVIDIA Surround is only 3x1. There is no intermediate 2x1 NVIDIA Surround option. Edited June 29, 2012 by BHawthorne
Jinja Posted June 29, 2012 Posted June 29, 2012 Sorry, and thx Brad! Did not know that nvid route can not handle 2x1, valuable tip. AMD can do 3d just like Nvidia 3d vision, right? i7@3.5Ghz, ATI 5870, 16GB RAM, win7 64bit, TH2GO, Track-IR, 4screen pit, TM WArthog HOTAS
BHawthorne Posted June 30, 2012 Posted June 30, 2012 (edited) Sorry, and thx Brad! Did not know that nvid route can not handle 2x1, valuable tip. AMD can do 3d just like Nvidia 3d vision, right? NVIDIA using Windows 7 or Vista has no 2x1 spanning mode on a driver level. You can use a Matrox DH2G or a MViewer box to achieve a 2x1 span. That is $250-$350 for a box. Using a Matrox box kills S3D as an option as they cap out at 60hz. That money is better spent on a second video card or some other hardware. Hardware spanning boxes are a legacy product that predate spanning modes on a video card driver level. They are a lot more limited in capability and are not cost effective. They are available if you have no other choice though. Zotac has a new active hardware adapter out that is DP-to-Dual HDMI. It is $45 directly from the Zotac website. You could do 2x1 spanning with NVIDIA using it, but hardly any NVIDIA cards are equipped with DisplayPort. If you're looking to do it on a new GTX670 or GTX680, this might be an option though for 2x1 spanning. The adapter is highly situational though as only a couple of models of NVIDIA cards are DisplayPort equipped yet. NVIDIA is very slow at adopting the DP standard. 600-series is only just now showing consistent addition of DP. My personal experience with S3D is with NVIDIA 3D Vision kit. AMD does have HD3D, Iz3D and DDD S3D options, but I have no personal experience with them. HD3D supposedly works with AMD Eyefinity. I used to do tech demos for AMD and we never got S3D working while I collaborated with them in 2010-2011. HD3D is a 2011-2012 development though and post-dates my tech demo collaborations with AMD. THe devil is in the details with a lot of these things. If you have any questions I'll be happy to help though. Edited June 30, 2012 by BHawthorne
Jinja Posted June 30, 2012 Posted June 30, 2012 The devils in the details indeed! Nvid 3d vis/ eyefinity / 2x1 .... Like the projector specs you were on about, all the pieces of the puzzle are there, just seemingly not in the same place at once! Maybe if i drag out the house renovatons long enough, the hardware will be another gen evolved... That and some fast jets will be waiting to be bought! :-) i7@3.5Ghz, ATI 5870, 16GB RAM, win7 64bit, TH2GO, Track-IR, 4screen pit, TM WArthog HOTAS

Just rattling around in my brain though. :smilewink:

Do you have any exp with the Intel cards that recently released in market?
