XL2546K gets even brighter with strobe utility. normal?

[rrisk93]

My Zowie XL2546K gets even brighter with Blur Busters strobe utility.

It is like this :

100% monitor brightness without Dyac+ → 350nit
100% monitor brightness with Dyac+ → 350nit
Max out brightness with strobe utility → 400nit

I can get even bright screen than default 100% brightness!

Good to have this, but I wonder why...

By default, XL2546K uses a rather severely voltage-boosted strobe backlight (overvoltage trick).

While this was not the intended purpose of Strobe Utility, so some pulse widths may create a slightly-brighter-than-factory strobe backlight mode on some models (e.g. XL2720Z version 2 firmwares had this 'bug' during VT1350);

Please bear in mind that longer pulse widths create more motion blur, so 400 nits may have more motion blur.

Be noted that voltage boosting can sometimes result in accelerated wear-and-tear on the LEDs. That being said, the difference between 350 and 400 is relatively minor. Ambient temperatures can affect this (summer and the lack of air conditioning) can mean 350 nits in a hot room will probably wear the XL2546K faster than 400 nits in a cold room.

Thanks for your reply.

I am glad I can use my XL2546K even brighter than factory setting with Blur Buster strobe utility, even if it is bug.

Also, I couldn't notice any motion blur difference between these two:

100% monitor brightness with Dyac+ → 350nit
Max out brightness with strobe utility → 400nit


Bright screen + 1ms motion clarity is so satisfying to see.

I'm kind of sad that there is no display except Zowie Dyac+ which have both "over 300 nit" and "BFI".

I want more resolution option like 4K but Zowie is not into it as you know...

It's normal. Though the brightness gets reset after powering the monitor off, so you need to re-apply the saved profile every time.
