Acer are on a bit of a roll now. Having recently announced the new G5 gaming monitor, the Touch LCD T231H and the stylish S273HL; Acer have continued their product rollout with an enitre new monitor series, the S1. The series consists of four screen sizes – 18.5″, 20″, 22″ and 23″. The 23″ S231HL has a very sleek 15mm thin profile, whereas the 22″ S221HQL, 20″ S201HL and 18.5″ S191HQL all have a record breaking 13mm thickness. This makes them an entire millimeter thinner than the already 2D-looking BenQ V920. Aside from the thin nature of the S1 series (courtesy of the LED backlighting), there is nothing particularly unique about the panels. The pricetags are fairly attractive: S191HQL (£119.99), S201HL (£129.99), S221HQL (£159.99) and S231HL (£169.99) and are due for immediate release. Read more.
