Setting up Three-Touchscreen System - Understanding How it Works
The following request stems from a desire to create a three-touchscreen setup with a new Intel Haswell box. I've tried to get answers from both Dell and from the box vendor (system house) with little luck in getting credible answers - they've been contradictory. What I've determined by experiment with an S2340T that I already own is that it works well with a USB3.0 connection to a computer (Surface-3 Pro), and doesn't have touch capability when using DisplayPort alone. What I've unsuccessfully asked Dell and the box vendor is whether three monitors connected solely by USB 3.0 will work effectively in an "extended" screen mode at a low frame rate - I’m not gaming. Hence my questions.
My usage would be with multiple programs simultaneously for productivity, not for video or gaming (i.e. not high frame-rate)
To be explicit, here are my proposed parts
CPU - Intel Corei7-4790
Motherboard - ASUS, Z97-PRO, LGA1150, Intel® Z97, DDR3-3200 (O.C) 32GB /4, PCIe x16 SLI CF /2, SATA 6Gb/s RAID 5 /6, SATAe /1, M.2 /1, DP + HDMI + DVI + VGA, USB 3.0 /4+4, HDA, GbLAN, ATX, Retail
Monitor - Dell S2340T
• Can someone explain or refer me to an explanation of how the video and touch signals are processed? I'd like to understand where the processing of these signals actually happens.
• Would this setup work in Windows "extended" mode so I have touch on all three screens?
• Would this setup markedly drag down overall performance of the system?
• Would I benefit from putting in video card(s)? If so how, and what kind would I want?
• Should the single Dell Display driver for S2340T cope with three separate monitors?
