Preset Color Accuracy

Aside from being to green and yellow, the UHD32R offers great preset color accuracy suitable for all but professional color accuracy related work.  The UHD32R can fully cover the REC 709 & sRGB color space, has quite accurate preset *gamma, and is free from color dulling horizontal (VA) and vertical (TN) gamma shift.  Since I'm used to calibrated monitors I do not find the UHD32R to be beautiful since it's too green and yellow, and because I have encountered cheaper monitors which are more accurate out of the box, however, the Qnix comes in 2nd place out of the six 32" 4K AHVA panels I tested which are the Acer XB321HK, BenQ BL3201PH (1st), HP Spectre 32 and Qnix UHD3216R.  The BenQ BL3201PH has excellent preset color accuracy superior to the rest, and both Qnix monitors best the Acer and HP despite costing significantly less, though the Acer and HP do come with a 3 year warranty and can be easily returned and exchanged in most countries.   

*The gamma curve is a bet skewed and less linear than that of the BenQ, Prism and Qnix UHD3216R, but 0-30% white tracks close enough to 2.2 to prevent the UHD32R from looking washed out (sub 2.1 gamma), and prevent black crush (2.3+ gamma).  The preset gamma is closer to linear 2.2 for REC 709/HDTV than it is to an sRGB curve.  The Acer XB321HK's gamma causes some dark shades and colors to be washed out, and brighter colors and shades to be too dark.

Unlocking the color controls by switching the Color Temperature setting to User in the color menu decreases the color accuracy a bit since doing so results in Blue being de-saturated and the green tint becoming slightly more pronounced.
