At work, four screens:
Left and Right Main screens: Soyo Topaz S (MVA) 24" @ 1920x1200 (5+ years old. Really nice for the price point, even today.)
Left Aux screen: Dell P2312H (TN?) 22" @ 1920x1080 (official work-provided screen. Really unimpressive.)
Right Aux: Dell 1908FP 19" (TN?) @ 1024x1280 (nice in portrait mode for e-mail)
At home, four screens:
Center: IBM T221 (IPS) @ 3840x2400 at 41Hz (amazingly beautiful and really hard to drive)
Left and Right: Samsung 2343BWX (TN?) @ 2048x1152 (nice quality panels)
Right Aux: IBM ThinkVision L170p (TFT) @ 1024x1280 (vertical for e-mail) (rotates well, old IBM LCD are pre-TN and look nice at any angle).
Thanks for sharing I'm curious to know how you utilize four screens?
Got any pics? And what video car/external dongle solution are you using?
I've been using three monitors for a while but have considering getting another.....just because!
At work: C# and SQL on left and right screens. E-mail, calendar on the portrait to the far right (out of immediate focus and less distracting). On the far left, SQL Profiler, task manager, Debug Trace, etc.
From left to right it's: Status, C#, SQL, E-mail.
At work, I've got a Dell Optiplex 990 with a single AMD video card (a 5450, I think). It has a DMS-59 output, which splits to dual DVI. It also has an on-board/on-chip integrated Intel video that drives a DisplayPort and VGA port on the motherboard. I recently learned that through some magic BIOS incantations and installing drivers in a very specific order, that one can drive all four video ports (Dual-DVI, DisplayPort, and VGA).
I've also used USB DisplayLink video converters (drives a 1900x1200 screen via a USB 2.0 port). These are handy but have some limitations (no video acceleration).
At home, driving the IBM T221 is super tricky and a long and expensive story...
