ScreenRecycler uses Macs, PCs as monitors

updated 02:50 pm EDT, Mon May 28, 2007

ScreenRecycler 1.0

One Mac developer has released ScreenRecycler 1.0, a utility designed to turn a second computer into a second screen. ScreenRecycle uses VNC as a transport protocol, enabling the software to work with PC and Linux systems as well as Macs. ScreenRecycler runs natively on Intel-based Macs as a Universal Binary, and uses Apple's Bonjour technology to automatically set up the network to enable another screen with no configuration. Once the connection is established, the extra display appears in the system preferences pane and is adjustable as any other screen. The software is priced at $30 and requires Mac OS X 10.4 or later, as well as a VNC client.

    Sounds neat. But. Why wouldn't you just plug in the second monitor directly into the main computer? Save yourself a whole lot of lag

    possible uses

    I can think of a few possible uses, including controlling presentations "remotely" and setting up another display when you have already maxed out your connections.

    For example, I've already got an external display hooked up to my MBP, and could often use a third screen. Software like this would make it possible.

    Guess I better go check it out. *grin*

    Re: umm

    Not all Macs support second monitors, and even less support three or more monitors. It has a few uses I can think of - showing information to a client sitting on the opposite side of a table - putting all tool palettes on the slow screen - monitoring applications that don't require fast graphics - cross-platform - use a PCs dedicated monitor as Mac's second monitor without requiring a KVM switch

    As well

    I think the big thing is that you can get a new Mac Pro while still making use of your old 17 inch iMac, I think that's the main sort of purpose. My only qualm is that the only other Macs I have are a 12 inch PowerBook and iMac G3 both of which I think would be too slow to do much with over VNC though who knows.

    aren't ya'll skeptics

    So did I get this right, screen lag? You don't get that on a well setup network. Not at all. Apple's using, essentially, a VNC protocol for ARD. It works fine, I use it day in and day out. VNC has come a long, long ways. I wouldn't expect to play warcraft on this VNC/Second Display, but utilizing a secondary monitor for pallets, a web browser, AIM, or a host of other programs I use on a daily basis would be more than useful. Not everyone *has* a MegaMac Tower. Many of us have iMacs and iBooks and the like, therefore this is an ideal solution. It sounds like it forces the display to appear in the system, chipset supporting multi displays of not (OS X is designed to work with however many video cards you have installed at present, so it cares not about this being virtual).

    From memory it is sluggish because it is VNC and it doesn't get around the theoretical number of monitors you can support.
