ASUS VG236H 23-inch 3D Display Review: 120Hz is the Future

Brightness Uniformity

For brightness uniformity, we test at the same 9 points we measure Delta-E on, but this time measure white and black levels when the center point is as close to 200 nits as we can get. We use the same colorimeter as before, again an Xrite i1D2 with ColorEyes Display Pro.

Brightness Uniformity - White

Brightness Uniformity - Black

Qualitatively, I never noticed a big change in brightness from right to left like these measurements imply. I was a bit surprised and measured three times, getting similar results. There’s a good 15-20 nits of difference at 200 nits from the right to left. It’s not killer, and honestly for a gaming centric monitor hardly an issue.

There was a bit of light leakage at the bottom and top of the display, however.

It’s noticeable when displaying a uniform black field, and most apparent at the very bottom right, as shown here. In normal use however I couldn’t tell it was there. Even playing Metro 2033 in the dark.
