One problem with that entry: the PS/2 only ever had a minuscule share of the market. In the clone world, which was the lions share (think Dell, Lenovo etc of today), resolutions were all over the place. So 800x600 was often the minimum resolution many developers were targeting for things like dialog boxes etc in that timeframe. It's a fiction to say there was a standard during that time, there were many. From SVGA (800x600) on, it was more a combination of user preference, monitor capability and any minimum software requirements as to what resolution a given user would run. Unlike digital LCDs of today, analog monitors didn't care what resolution you ran them at as long as they could handle the horizontal/vertical frequencies you were throwing at them and the phosphor mask had the resolution needed. (and if it didn't have the resolution, the picture would just look progressively more blurry as you jacked up the resolution being sent to it)
