I do not think you will find a 20" monitor in that resolution. The standard for 19" wide-screens is 1440x900. There are some available in 1366x768 but that is a bit of an oddball setting and is mostly available in older screens, just get a standard 19" screen or a 20" one. Here is a cheap well rated Acer http://www.newegg.com/Product/Product.aspx?Item=N82E16824009317
