The XL2546 has the same increased smoothness that was introduced in the XL2540 and the addition of DyAcTM provides increased movement clarity in-game.
240Hz gaming monitor
New to the XL2546 is the DyAc technology that Benq previously applied to the older XL2735 240Hz Pro Gaming Monitor and the XL2540. The benefits of the XL2546 and its native 240Hz refresh rate can be fully activated when the computer generates over 240 frames per second(FPS). So you should make certain your PC performance is up to par before considering either monitor.
Only a few gaming monitors currently offer refresh rate of 240Hz, although the use of as many frames per second will be limited to most people. The XL2546 is aimed primarily at e-sportsmen who play at (semi-) professional level.
The ZOWIE XL 2546 with DyAc will make its tournament debut at DreamHack Atlanta 2017 where it has been selected as the official monitor.
