In deciding what graphics accelerator to buy, make sure you weed out those that support only resolutions that are used in interlaced mode, because eyestrain will result if you work for long periods of time with an interlaced display. Nevertheless, vendors continue to provide interlaced modes, even though monitors designed with the slow phosphor needed for interlacing are rare. Worse, many vendors don't make it clear what resolutions require interlacing. We strongly suggest that you ignore interlaced modes when making your purchase decision.
Also, be wary of advertised resolutions that require 90-Hz refresh rates. Usually, this indicates that interlacing has been implemented by the vendor: The actual refresh rate is 45 Hz, which is doubled to cover the two refresh sweeps.
At the time of our testing, all the DRAM-based boar
ds implemented interlacing in modes that required 2 MB of memory. For this reason, we recommend that you purchase DRAM-based boards with only 1 MB of memory if they only run interlaced modes with 2 MB.
