REVIEW: Eizo CG246 Part 3


Power consumption

Compared to monitors with IPS panels and CCFL backlighting, the CG246 uses around 25 per cent less power. Conversely, it consumes around 25 per cent more power than similar monitors that use laterally installed white LEDs for illumination.

When the monitor is connected to a computer via USB, the monitor’s power switch should be turned off to ensure that there is no standby power drain.

Connections

The Eizo CG246 provides a total of three video inputs. Users can choose between DisplayPort, HDMI and DVI. The DVI input also accepts analogue RGBHV signals.

Two upstream USB ports are provided to connect the built-in USB hub to a computer. Both of these ports are located on the rear and can be freely assigned to the video inputs.

Operation

Seven buttons with a pleasantly low pressure threshold are available for controlling the monitor and OSD functions. These are recessed into the bottom part of the frame and have low-level backlighting. Their current functions are shown on screen when used.

Two arrow buttons are available for navigating through the OSD and adjusting the selected parameters. Frequently used functions, such as screen brightness and signal input, have their own buttons.

OSD

In most cases, the included hardware calibration functions negate the need for any OSD changes. Nevertheless, Eizo is rather generously providing an extensive range of on-screen settings for the CG246, which can be accessed via six main menus.

The brightness control is a new feature; this directly changes the backlight intensity. Instead of percentage values, the settings use absolute cd/m² values. The desired white point can be selected from a range of Kelvin presets, or it can be freely adjusted via three RGB gain slide bars. Gradation can be changed using the gamma slide bar. This is limited to fixed settings (1.6 to 2.7) but the predefined image modes also reproduced their designated tonal value curve. A total of three user presets are available for storing the hardware calibration settings. This allows every signal input to be calibrated separately.

The overdrive circuit is enabled and disabled via the OSD. When the source signal is supplied at a non-native resolution, the scaling can be adjusted via a separate slide bar. The display can be set to be either proportional, full screen or unscaled. For the HDMI input, these options are adapted accordingly. A number of other parameters can also be changed, such as the settings for the deinterlacer.

Self-calibration is configured using a separate menu. The required target parameters are determined from the advance calibration performed by Color Navigator. However, users can also manage all of the settings, such as a detailed time schedule, from within the software.

The remaining functions include menu language selection and OSD position. Naturally, it is also possible to restore the factory settings.

Thanks for this review, I bought this display, by far the best one I've owned.
I'd need an information: I 'm about to buy a device that use hdmi to output a 10bit video signal, but only dp is 10 bit in the 246; so is enough to use a hdmi/dp cable or adapter or I'll have 8 bit signal?

I'm unable to guarantee that. You will need a HDMI to DisplayPort converter - not a simple cable - because of different protocols used. A 10bit workflow is in principle not a problem but it depends on the capabilities of this converter.
Perfect, I'll look for a proper converter,
thanks a lot

best regards
sam
