Multi-screen Output for single PC (8.1)?

    Hi all,
    It has been my nerd dream to have many screens to be able to see the same PC (Win 8.1)output in more than one screen. Other than the obvious way of having the same input in many PCs simultaneously, is there some other way of doing this, while having the option of doing basic functions on the additional screens, e.g., scrolling up or down. Should I just get a few monitors and attach them to my PC, together with some change of settings in the "main" PC ( the one that is receiving the input from me)?

    Yes, definitely possible and it also utilizes your PC 8.1's CPU and RAM to display its windows on those monitors.

    Thanks, seems like that should be enough monitors!

    :biggrin: I don't know about your actual need. My classmates here also shared their stories of getting new job interviews for technician positions in other companies today and you guess...
    More Free Advice is needed about this.

    If you have a relatively modern PC you probably can put at least two monitors on it. Many support three or more. Look at the back of your computer an find all of the video outputs.
    Use the digital ones first:
    https://en.wikipedia.org/wiki/DisplayPort
    https://en.wikipedia.org/wiki/HDMI
    https://en.wikipedia.org/wiki/Digital_Visual_Interface
    [/PLAIN] [Broken]
    This one is usable too but lower quality:
    https://en.wikipedia.org/wiki/VGA_connector

    Some systems will only allow certain combinations to be used. Usually there is a limit to the number. You have 4 connectors but any three may be used. Sometimes the VGA connector will only work if a certain other digital one is not used. The instructions will have that information. If you need more you usually can add more video cards. As a last resort use USB to video converters.

    Once you have that sorted you need to set them up. There are many different options depending on your OS. Each has a default way and the video card manufacturer may have their own way.

    In addition to my 8.1u1 PC's internal graphics system running this 19" wide-screen #1 at 1600x900, I've an 'inexpensive' USB 2.0 DisplayLink DL-165 device driving the adjacent 19" wide-screen #2 at the same resolution, both via DVI.
    So, I've an effective screen size of 3200x900.
    :-)
    Thoughts...
    1) It is CPU-intensive. Sadly, my 1.5 GHz, 6Gb PC has a 'black box' warranty, so I'm restricted to external augments.
    2) The 'out of box' device only offered a lower resolution, but DisplayLink's site had an upgraded driver available.
    3) There's later devices with USB 3.0 interface for true HD working. Sadly, this PC also lacks any 3.0 ports...

    As ever, YMMV...

    { I'm still hoping to 'break ground' on a home-build CAD PC with six nimble cores, 32 GB fast RAM, a dual-DVI card etc etc but 'real world' stuff has priority... }

    A USB 3 video card is similar to the order of magnitude speed of a 1xpcie video card. If your system supports a faster interface (4x pcie?) you will have much better performance. That 1x speed can be annoying due to bandwidth limitations but still definitely usable.

    Your CAD experience may be limited on the USB monitor. However if you only use it for the palettes and tools it should be well within it capabilities.

    Edit: You are talking AGP level performance. We all saw that as blinding speed back in the day.

    I spread my budget TurboCAD Deluxe's palettes and tools around the eight feet of screen edge, have multiple views in use. I've no significant latency during editing. Of course, I'm only working at 'hobbyist' complexity, but my models do include a lot of custom architectural detail like Medieval-ish arches, doors and windows, down to their 'soldier bricks' and hob-nails...
    Rendering is as slow as you'd expect...
    ===
    FWIW, there's a *nasty*, decade-old bug in the Deluxe version's 3D Booleans, such that one-too-many 'slices / dices / welds' will 'lock-up' an object, preventing further Boolean operations. Gotta 'undo'. As I understand it, legacy licensing issues preclude patching.

    This does NOT apply to the wondrous 'Pro' engine, but my version was too old to re-install. Registration system didn't accept it. {Weep...}
    And, yes, you do need a $2k workstation to run the now-$1k Pro and its remarkable tool-kit.
    Remember that scene in 'The Matrix' when they ask for guns ??
    Oh, yeah...
