The Acer H235H is typical of this class of displays: It’s based on a six-bit TN panel that uses frame-rate control to augment its color depth. The screen delivers 23 inches of viewable area at a native resolution of 1920x1080. As with nearly all the monitors we tested, we found it necessary to make significant adjustments to the display’s brightness and contrast settings to make the monitor look its best with our DisplayMate benchmark software. But the five touch-sensitive buttons in the Acer’s glossy black bezel and the obtuse icons in its onscreen display make this process extremely frustrating; the onscreen icons don’t line up precisely with the physical buttons and it takes too many button presses to drill down into each menu choice. It takes five button presses, for instance, to make a single brightness adjustment.
