The Acer SB220Q monitor is based on an IPS panelwhich delivers accurate, consistent, and intense colors that will breathe life into games, movies, and everything else you’re watching, when compared to the usual monitors with TN panels you can find at this price point. Another thing that makes the IPS panel superior to TN and VA panels is the viewing angles of 178 degrees, both horizontally and vertically, which ensure that the picture won’t shift in color and contrast when it’s viewed from skewed angles. Although the Acer SB220Q is a bit smaller in size when compared to the popular 24-inch budget variants, there is an upside to it; since the screen is smaller, the screen resolutionwill have a more dense pixel count making the picture clearer with more details and screen space. 

Speaking of overdrive modes... let’s take a look at response time performance. Ther are three avialable modes: Normal is the default, there’s also Off and Extreme. Off is very slow, we’re facing a 16.24ms grey to grey average which is typical of entry-level 1080p IPS panels without overdrive. Ghosting is significant using this mode, with long smear trails following moving objects. Only 27% of transitions come close to meeting the lengthy 13.33ms refresh window, so this mode simply isn’t fast enough and wouldn’t be great at 60Hz either. Acer SB220Q - Overdrive Off (75 Hz) Normal takes things the other way, now we have a 6.40ms grey to grey average which is decent for an IPS monitor, and allows the SB220Q to achieve 100% refresh rate compliance. However, this has come at the expense of overshoot, and quite a significant amount of overshoot. An average error rate of 14.6% is high, and around half of all transitions experience inverse ghosting. Plenty of transitions are above 25% oversh...
