Q1: Will DyAc/DyAc+ increase input lag?
A1: The DyAc/DyAc+ won't add input lag, since it doesn't add any extra loading to the image processing to the monitor nor to the computer.
Q2: Why the brightness drops when I turn on DyAc on my XL2411K?
A2: This is due to the 144hz panel limitation. This phenomenon won't happen on our 240hz with DyAc models.
Q3: How much the brightness will drop when I turn on DyAc on my XL2411K?
A3: It is roughly 50% off, and the perception to the brightness drop may be different depending on each one's feeling and ambient conditions.
Q4: Is DyAc/DyAc+ compatible with GSYNC/FreeSYNC?
A4: DyAc/DyAc+ is not compatible with GSYNC/FreeSYNC, so when you turn on GSYNC/FreeSYNC (if your model has one of those variable refresh rate features), then the DyAc/DyAc+ will be off automatically; If you want to turn on DyAc/DyAc+, you need to turn off GSYNC/FreeSYNC through your graphic card control panel. The way DyAc/DyAc+ works is different from those variable refresh rate technologies, and DyAc/DyAc+ provides different benefits compared to the others:
• DyAc/DyAc+ provides a clearer dynamic vision based on a high and stable refresh rate and fps
• Variable refresh rate (GSYNC/FreenSync): reduces stuttering and tearing when there is a significant gap between fps and refresh rate, or it is under a low fps and refresh rate
Q5: Does DyAc/DyAc+ work on console or does PC need special requirements to be compatible with DyAc?
A5: DyAc/DyAc+is an independent feature built into the monitor that can work on any PC or console but DyAc/DyAc+ will be only active when the input content is 100hz or above.
