Hi everyone,

I have a Eizo cx240 that I recently bought for broadcast grading.

An expert on monitor calibration recommended it to me and he also did some calibration (rec 709) on it with CalMan.
The thing is I'm not satisfied with the result. Although his reports says it's calibrated, it feels green and the luminance is so much lower then what I'm used to.

Is this what to expect from these cheaper monitors?


It's connected to a Avid Symphony via a Blackmagic Decklink Studio over HDMI.

Is it really possible to change the internal LUT table of the monitor with CalMan?

Which luminance are you using?
You are free to change it.

What do you mean with "green is much lower"?

The CX240 has a much wider gamut than rec 709 so it can easily display any color correct in emulation mode.

The model of Eizo display you have cannot use 3D LUT calibration, and relies on a simple matrix and 1D LUT.
This will not give as precise control as the use of a 3D LUT.

But, it should be possible to calibrate to an 'acceptable' level with just those tools.

Well the luminance thing is to be expected. Most monitors default to settings that are 150cd/m^2 or greater 200+ is not uncommon. I don't know what you calibrated to or what you previously were using, but the 80cd/m^2 - 100cd/m^2 is a typical target for color critical work and will be much dimmer than you are used to. You should be doing color critical work in a dim room and the display for your computer should also be lowered to the same level or even lower in order to those luminance levels to feel correct.

As to the greenish cast you feel like you saw, what meter where you using and what calibration table were you using?


That monitor is an excellent display and you should get excellent results from it.
