A-MVA vs H-IPS, which is better?

[EsaT]

Is it as simple as that ? I thought to alter the luminance of the back light you altered the frequency the CCFL ran at.

Back light's PSU surely has some components for setting its operation because I don't see them making some special PSU with brightness "hard" selected by transformer components.
Most likely they just used generic PSU and left out software control part.
Year and half ago there were some cheap MVA paneled Iolairs which had fixed backlight and after finding datasheet of back light PSU's controller some modified it to use potentiometer/rheostat for adjusting brightness.

Have you a link for this ?

In case there's any confusion I tested the original hz26w before the firmware update. In the ver I tested there was no backlight control and so black depth was poor and contrast stability did not behave correctly. Believe this has been addressed to a degree in the hz26wi ver but only by lowering the intensiy of the backlight overall. It still does not offer actual control of he backlight but it has at least helped improve min black depth.

Contrast ratio and black depth are prob the main areas of difference between an ups panel such as this, and an AMVA panel. The ips panel will also offer you slightly wider iewing angles and is free from the off-centre contrast shift you can see from VA matrices as you move away from a head on view.

Gamma shift is more describing because darkest shades tend to melt into one shade/their differences are compressed from straight angle and when looked from off center VA-liquid crystal's gamma returns closer to ideal curve:

I don't think you'll understand Finnish...
