Updated iMacs may use anti-reflective technology from Taiwanese supplier G-Tech Optoelectronics, according to DigiTimes. A new report cites "industry sources" as indicating that G-Tech will "supply AR (anti-reflective) glass solutions for Apple's all-in-one (AIO) PCs." Current-generation iMacs use purely glossy screens, which can potentially create problems in rooms with bright lighting. "Antiglare" options are only available on some custom MacBook orders.
