Quick verdict
The XL2566X+ gives competitive players ZOWIE's second-generation DyAc strobing, the same bearing-mounted stand, shields, and S Switch as the flagship, and a 400Hz refresh rate that more PCs can actually feed. For most players the step from 400Hz to 600Hz is harder to use than the step from 240Hz to 400Hz.
We rank it on specifications and on independent testing of its sibling models, because we did not find published measurements of this exact model. Its HDMI ports are 2.0 and stop at 240Hz, so use DisplayPort for 400Hz.

What independent testing reports
We did not find numeric measurements for this exact model that we could attribute with their test conditions. Statements below are either manufacturer specifications or reviewers' qualitative findings, and each one says which.
Motion, response, and latency
At 400Hz each frame lasts 2.5 ms on a sample-and-hold display; DyAc 2 strobing shortens how long each frame is visible, which reduces perceived blur further. ZOWIE describes DyAc 2 as using a dual backlight design. We have not found measurements of crosstalk, response, or lag for this exact model, so we make no measured performance claims.
Image quality and HDR
ZOWIE lists 320 nits and 1,000:1 native contrast on a 24.1-inch Fast TN panel. Expect typical TN trade-offs: narrow viewing angles and color that shifts off-axis. Specification-based only.
Connectivity, PC, and console notes
One DisplayPort 1.4 for 400Hz and three HDMI 2.0 ports that stop at 240Hz. Consoles run at 1080p 120Hz. ZOWIE includes DisplayPort and HDMI cables.
Warranty and ownership
As an LCD, no burn-in concern. Warranty length is not listed on ZOWIE's US page.
Warranty: Unknown (not listed on the US product page)

Questions buyers ask
Should I buy the XL2566X+ or the XL2586X+?
If your PC rarely exceeds 400 fps in your main game, the XL2566X+ gives you DyAc 2 and the same ergonomics for less. The XL2586X+ adds 600Hz and HDMI 2.1.
Final recommendation
For most competitive players who want ZOWIE's DyAc 2 experience, the XL2566X+ is the better value than the 600Hz flagship. Choose it knowing our assessment is specification-based.
