Do I miss my XL2566K now? No not at all. Pretty happy with my new purchase for that low price. Plus I want that feeling out of my system that I did not missed out on any experience on the different monitors that pro players still uses till this day to see what suits me best. Apex feels very good on the VG259QM. Better then on the XL2566K to be honest, but could be a honeymoonfase. If I would try a other monitor now I would buy XL2546K again but not more then 230 euro second hand.
I personally will not have fun trying to find the right panel, I have already forgotten the VG259QM for a long time, it would be interesting to talk to Rtings about it but I doubt that they will test the QSIDA panel.
It may be better (and besides I think it will be very easy to do better than the ultra disgusting AUO panel) initially on the VG259QM.
After all, their saturation and their black EQ has Asus is not the best implementation, at least with my own eyes.
After all anything 280hz or OC mode I don't care I mainly play Apex Legends and looking for a factory native 240hz even with 280hz > 240hz QFT CRU I'm not a big fan, and I try if possible to stay in 27 inches if I can, after that doesn't surprise me, especially for Apex, the XL2566K is absolutely not a good choice and a good value for money, if you do a custom res with CRU in 240hz/fps yes, but personally I'm not too interested on that, and it's like you, I no longer want to buy something supposed to be
future proof, no, I want to buy something that corresponds well to the present moment with my machine, that's why I don't play in 1440p anymore.
I currently have the XL2746S for testing, it's 1080p 240hz but at 27 inch and before buying that I spitting on the 1080p 27 inches because it was too blurry, etc.
Well I'm just shocked, this one is necessarily less detailed but is not illegible, I think especially because the sharpness management and the anti-reflection treatment at Zowie is better than Alienware (because I had already tried 27 inches 1080p before but it was on Alienware and I found it infamous, like Dell.)
And for Apex, you are 27 inches so you can see very well but while having 1080p 240hz DyAc+, clearly with 1080p you have incredible performance, the DyAc+ on this one works very well and is very bright, on the other hand if you want to photoshop or do some color or detail precision, it's clearly not the one to take but in office automation, I make a specific profile (less saturated, softer) it's fine! (
but like some TN, some smearing when you scroll text.)
