All the Dell models? My 2405FPW certainly doesnt, and tbh the backlight issues in the Dell range are pretty much exclusively in the 2005FPW stock.
Regardless, if you're looking for a fast TFT for gaming above the 19" range then it might be advisable to wait a little. While the Eizo S2110W is no doubt an excellent screen, it is not really very responsive for gaming, and moving from a fast TN Film model like your current VX912, i think you might notice a drop in gaming performance. There are a few nice 20" models emerging including the Belinea 102035W which is the first of range to be using AU Optronics' new 8ms P-MVA panel, which is effectively a larger version of the 19" panel used in excellent models like the Viewsonic VP930. There are also a few TN models emerging in the 20" market, but i think it is a shame to sacrifice the viewing angles and other areas when you can get fast P-MVA panels like the Belinea. The new Dell range should be good too, including the updated 2405FPW v2 model which should hopefully be using Samsungs new 6ms PVA panel. This was rated highly by BeHardware who noticed an improvement in real responsiveness compared with Samsung's previous 8ms and above offerings. There's plenty of good models on their way this year, but for now, the Belinea is about as fast as you'll get in the 20" and above range.
