Several Blur Busters readers, forum posters, and Amazon.com customer reviews have consistently mentioned BENQ XL2420TE (and its UK sister, XL2420T Revision 2.0) have less eyestrain and better color quality than the ASUS VG248QE.
The BENQ XL2420TE has been confirmed by many to have:
– Wider brightness adjustment range from very dim to very bright;
– ZeroFlicker is more eye-friendly with PWM-free dimming; fewer headaches;
– Better default colors than the ASUS VG248QE.
