EIZO has three ColorEdge 27 inch monitors in their range: EIZO ColorEdge CG277, EIZO ColorEdge CX271 and EIZO ColorEdge CS270. As you read down the specs you may be hard pressed to spot the differences but they are there. The CS, CX and CG models are each designed and targeted at slightly different types of customers, in this post I’ll try and outline not only the differences but the practical implications of those differences so you can better choose which is the right monitor for you.
All three models have an LCD panel with an LED (light emitting diode) backlight. The back light has green and blue LEDs and the red is then created using filters on the green and blue. This means the monitors cover and impressive 99% of the Adobe RGB colour gamut. All three models also come with EIZO’s standard 5 year warranty.
The ColorEdge CG277 has everything you need for achieving the very highest standards of colour accuracy and consistency. It all starts in the factory where the panels are measured, selected, corrected for uniformity variations and adjusted for gamma. All that means that you receive a very uniform and accurate monitor. The CG277 comes with a built-in self calibration sensor that works with the bundled ColorNavigator software and can be set for automated self calibration. ColorNavigator is easy to use and adjusts the monitor to whatever calibration targets you set. The CG277 also comes with a shading hood.
So, the CG277 has everything you need to be very consistent and accurate over its minimum five year life. The fact that it can self-calibrate means that it is ideal for those customers who find calibrating their monitor arduous or confusing, and because each self-calibration sensor is matched to each screen it also means that the calibrations are very, very accurate. So if you are a retoucher, top level professional photographer or anybody else who needs or wants the very highest level of accuracy then the CG277 is the one for you. It also has advantages if you are grading or editing video or movies. The CG277 supports 3D look up tables meaning that it can emulate different TV and motion picture standards (such as Rec. 709, EBU, SMPTE-C, and DCI) and custom film look up tables. It also supports downscaling of 4K to 2K signals.
Of course, all that quality and accuracy comes at a price. So EIZO have pitched the cheaper ColorEdge CX271 at a slightly different type of customer and have left out a few of the bells and whistles of the CG277. The most significant change is the omission of the built-in self calibration sensor. Instead the CX271 has a self-correction sensor. You’ll need an external colorimeter or spectrophotometer to calibrate the CX271 with the supplied ColorNavigator software, such as the i1 Display Pro. During calibration with ColorNavigator the self-correction sensor takes a measurement of the screen brightness and can then be set to measure and adjust only brightness periodically. The CX271 doesn’t come with a hood, pixel warranty, 3D LUT or 4K to 2K capability.
The ColorEdge CS270 is the newest of the three models. The CS270 is similar in spec to the very popular 24 inch CS240. It offers many of the benefits of the ColorEdge range, such as hardware calibration with ColorNavigator, but doesn’t have a built in colorimeter or brightness sensor. It’s a great choice for an amateur or semi-pro photographer and beats the socks off competition from Dell and other manufacturers, not least because you still get the full 5 year warranty.
The CX271 and CS270 are significantly cheaper than the CG277 – although one thing to bear in mind is the cost of an external calibrator if you haven’t got one. If you are a pro photographer, retoucher or video editor/colourist then the CG277 is the probably the product you should aim for. If you are a photographer on a tighter budget and have a colorimeter already, or you are a graphic designer then the CX271 is probably a good level for you. If you are an amateur photographer then the CS270 has been pretty much pitched at the level you need.
