XL2546K vs XL2546S

Post by CortexFPS » 04 Jul 2022, 14:00

I do this post in the hope of some owner or former owner of XL2546S. I had an XL2546K for many months but then I decided to sell it. A month ago I bought a used XL2546S, because having gone out of production prematurely and many people were enthusiastic about it, I decided not to miss the opportunity. However, I noticed that with Dyac Premium and AMA High, the 2546K in the UFO tests was very clear with some crosstalk, while the 2546S has a bad afterimage behind the UFO. Do you know if it has a worse overdrive implementation?

I attach a quick photos of XL2546S:

The overdrive values are different.
You can reduce the overdrive level of XL2546S to XL2546K levels by changing the OD Gain value in the factory menu.

From the factory menu I was able to reduce AMA High to a better value, too bad I found that all Zowie monitors when the monitor is turned off, the changes made in the factory menu are not saved, thanks anyway for the help guys. For the next who will read this post, I can tell you that it is not true as Zowie claims that the 2546S and 2546K are the same monitor, they are the same panel but not the same, the 2546S has a different build quality, but the 2546K is calibrated better by having a better quality of movement.

If the monitor is new (less than 10 hours of use), try a 24/7 burn-in 100% brightness. For a few days.

LCD GtG and crosstalk doesn't fully settle to final levels until broken-in after its panel factory manufacture. Getting the Liquid Crystal fluid (in L.C.D.) loosened up inside the panel glass sandwich and redistribute that fluid throughout, etc.

Also, if it is winter in your hemisphere, remember cold panels will crosstalk more than hot panels in summer. LCDs slow down with temperature. So if you last tested an XL2546-series in summer and sold it, and got another XL2546-series in winter, you will definitely see these crosstalk differences. If it's a winter-vs-summer issue, try running the monitor hot (disable screen saver, leave monitor on 24/7, and/or display a black screen to absorb maximum backlight to heat up panel to compensate for winter coldness) and see what happens.

Panel lottery (manufacturing variances) can also have an effect. If that becomes the case, this may be a SOL situation. Possible workaround is adjusting the OD Gain in service menu, but the monitor conveniently "forgets" it so often.

I already knew all these things, I have read practically every post of yours, I have learned everything I know about the monitors from you, thank you very much. However XL2546S already has two years of life, so unfortunately it's not a problem with the panel, I'm using it at maximum brightness, plus here in Italy it's getting very hot, I'll try to do it anyway, thanks a lot for the advice, you are the best!
