Samsung 226BW A and S series: The verdict
by Vincent Alzieu
Published on May 9, 2007

226BW A: 2 or 5 ms ?
Put yourself in the seat of someone who has purchased a 226BW A, if this isn’t already you. They bought a screen for its extraordinary reproduction of colors-we said it and other PC magazines did as well. And then there is this dominance in blue. Arrgh ! They look for the panel and find an "AU Optronics M220EW01" – which corresponds to an AUO 22 inch panel, however, a 5 ms.
There are some who would take this very badly indeed.
For example, myself for one. At this point a jury of techie nerds would acquit me of almost anything.

Luckily (!), we don’t have to go this far as the panel is indeed a 2 ms. Actually, it’s a 5 ms with an optimised overdrive. As a reminder, Samsung calls its overdrive, RTA, for Response Time Accelerator and only they can use it. This is why it’s strange to find the RTA function in a hidden menu of an AU Optronics screen, something they could not do without Samsung’s consent. This reinforces the hypothesis that Samsung simply delegated the manufacturing of some of its screens to AU Optronics and CMO, giving them precise instructions and even specific components. Either way, the RTA function found in the series A tends to suggest this.

We therefore, conducted our usual tests, with the RTA activated and then OFF (default mode) and compared all results with the 225BW, a TN 5 ms :

The 226BW A and 226BW S are strictly identical in games, movies, and everything in movement. The A is thus also a 2 ms.
It was interesting to note that without RTA, the A and S were no better than the 225BW. They all become equally slow when deactivating this function and the 2 ms appears to be a 5 ms with an optimised overdrive.
