Eizo fixes 'Jumping Mouse' problem with some Macs

We've recently become aware of a firmware update that can affect some Eizo monitors.

The symptoms are a 'jumping mouse pointer' on screen, when the monitor is connected to an Apple Mac using the Mini DisplayPort connector.

As far as we know, only certain models, and with certain serial number ranges are affected.

Applicable Monitors: FlexScan SX2462W, SX2262W, ColorEdge CG245W, CG243W, CG223W

Applicable Serial Numbers

Monitors	Serial Numbers
FlexScan SX2462W	Up to 46298080
FlexScan SX2262W	Up to 27256100
ColorEdge CG243W	Up to 21734080
ColorEdge CG245W	Up to 47094080
ColorEdge CG223W	Up to 25363070

Description
When connecting the DisplayPort of certain EIZO monitors with the mini DisplayPort of certain Macintosh PCs, the mouse pointer may jump.

Counter-Measure
Eizo are providing a software update for the monitor firmware that will improve this situation. Please read the user's manual included in the download file before installing the software.

Notes on Installation

Applying the software will require a Windows PC*. Please be sure to conform to the following notes or your monitor may have troubles.

• It is recommended that you install this software only if your monitor has a relevant serial number. If it does not, a failed installation may damage your monitor.
• Do not plug in any device to the USB downstream port of the monitor. The device may break.
• Quit all applications before updating the software and do not run any applications while it is being installed.
• Set the PC so that it will not go into standby, sleep, or suspend mode.
• Set the PC so that the screen-saver will not run.
• Do not turn off the monitor and the PC during the installation. It may damage the monitor.
• If you use a laptop PC to install the software, be sure to use the AC adaptor.
• Do not unplug the USB cables during the installation. It may damage the monitor.
• Do not operate the monitor when the software is being installed.

* Now you'll notice that although the problem only affects Mac's, the software that can perform the firmware update will only run on a Window's PC which is bizarre to say the least! Apparently Eizo only produce firmware updates (which are very rarely required), using Windows-based development software.

However, the good news, is that if you're based in the UK, Eizo UK will perform the upgrade free-of-charge for you under the warranty. If you would like to get this, please contact Eizo UK on 01344 355720 or email info@eizo.co.uk

10-bit Graphics on Mac's

This article has been adapted from information provided to us by Quato - many thanks to Quato's technical team for their help and assistance. The article refers to Quato's displays, however, the advice is also relevant other 10-bit capable displays such as the Eizo CG223W, CG243W, CG245W and the NEC SpectraView 241W and 271W.

Some of you have already realised that the Quato IP242ex and the Quato IP240ex LED support full native 10bit via DisplayPort because the panels are also true 10bit savvy. However, the proof of concept is one thing, real world usage is another.

Actually, the Mac OS X 10.6 Operating System is only able to display 10bit via OpenGL and not via standard CoreGraphics applications. That means, to display 10bit via DisplayPort (DVI has not enough bandwidth for 10bit) you need both, a graphic card and an application that supports 10bit via OpenGL. Only the Radeon HD4870, HD5870 or Nvidia Quadro 4000 (fermi based) support 10bit on the Mac. Unfortunately, this also means you need at least a Mac Pro. Apart from some 3D Rendering software, only Photoshop CS4/CS5 support 10bit via OpenGL – means the OpenGL feature must be switched on in Photoshop CS4/5.

Thus, the only working 10bit combination is actually a Mac Pro under Mac OS X 10.6 with Photoshop CS4/5 and either the Radeon HD4870/5870 or Nvidia Quadro 4000 (fermi). The graphic card will at least cost 500 € but stunning smooth gradiants and finest details in the darks may justify this extra cost

All other Macs with integrated DisplayPort or Mac Pros with a DisplayPort equipped graphic card other than the 3 above only use 8-bit. Although the interface can theoretically do more, the used ATI/Nvidia/Intel HD graphic chips and drivers do not support 10bit. Thus, there is no solution to get 10bit out of these units.
