Something else..... gamut coverage - standard sRGB and wide gamut (WG).

Most CCFL back lights offer reasonable coverage of the gamut they are designed for. Typically about 96-98% (measured) for standard sRGB gamut monitors and about 100% (measured) of sRGB and 100% of AdobeRGB for wide gamut monitors.

LED's have not been quite as good. Up to a couple of months ago a typical white LED provided about 94-95% (measured) coverage of the standard sRGB gamut. These sRGB units also have a notable spike in the blue spectrum that has to be compensated for.

With wide gamut monitors, a RG+B-LED back light could do about 100% of sRGB and AdobeRGB. RGB-LED back lit monitors are rare and very expensive.

In the past 2 or 3 months we've seen some monitors introduced with the latest generation of LG Display's IPS panels and a new back light system. The new white LED's provide about 98-99% coverage of the standard sRGB gamut while a new GB-LED provides about 100% of the sRGB and AdobeRGB spaces in a wide gamut monitor. These are discussed in reviews of the Dell U2413 (WG), U2713H (WG) and U2713HM (sRGB) monitors on TFT Central. Costs for the GB-LED back lit wide gamut monitors are much much lower than seen with the older RG+B-LED system. I expect a slew of new monitor introductions or updates due the new GB-LED system.


You're going to have to do a bit of homework....

I'm wondering what effect using OLED displays might have on this.  Since they are not backlit, I wonder how their brightness and gamut will work out.  In some ways, I understand the impetus to use the widest gamut possible all the way through your workflow, but then to output to printers that can barely handle sRGB is somewhat disappointing.

Only my opinion. It's worth what you paid for it. Your mileage may vary! ;-}
