XL2566X+ vs XG27ACDNG: My Decision and Thoughts

FYI: This is not a panel comparison post—this is a purchase decision post!
I've decided to give the Zowie XL2566X+ (TN) a shot. I currently use a ViewSonic XG2431 (IPS) and a 105Hz CRT. I'm fine with the colors and brightness of the XG2431 (even with BFI off), but I want a display that’s brighter, has decent colors, and excels in competitive FPS tracking and reaction times.
I’ve read the new TN panels (XL2566X+) have better colors than older models, but I haven’t tested them yet. For context, I couldn't stand the colors on the XL2546K—they were terrible compared to the XG2431. However, the XL2546K did have better BFI and panel response.
I know most people would recommend the Asus XG27ACDNG (OLED) for its lower response time and superior colors. But without BFI, I’m unsure it would provide the consistency I need for FPS tracking. Based on slow-motion comparisons between a 540Hz TN and 480Hz OLED, the OLED looks better (no double-imaging), but I feel like tracking-focused games (Apex, CS, etc.) might benefit more from the 400Hz BFI TN.
For me, 360Hz-400Hz is the sweet spot, and with Zowie’s additional visual features (sharpening, color tweaking), I believe I’ll prefer their 1080p TN panel. While 1440p OLED is appealing, I’m not ready to sacrifice frame rate and motion clarity at this price point (~$650-$700).
It’s a gamble choosing TN over OLED, but I already have an IPS for casual gaming. If the XL2566X+ colors aren’t significantly improved over the XL2546K, I’ll be disappointed, but I’m cautiously optimistic.
Specs: R7 7700 + RX 6800 XT
Games: Apex, Fortnite, The Finals, OW2, CS, and more (usually on stretched 16:10 or 4:3 resolutions like 1440x1080 or 1728x1080).
Does my reasoning sound solid? I’d love to hear opinions from anyone who’s tested these displays!

By saying "
FPS tracking" did you mean 1) tracking eyes or 2) tracking aim. The term is a bit confusing because the two are not the same. BFI doesn't help #2 as much as #1. And I'm sure there is more #2 situations happening in competitive FPS games than #1. I wanted to point this out because I feel like many are not aware.
- Example of tracking eyes: https://youtu.be/kXQZ85B053s?si=h7LHTcATrao2MkPJ&t=504 (8:24-8:28, timestamp included)
- Example of tracking aim: https://youtu.be/kXQZ85B053s?si=NIfVjx5ARsTLNAvN&t=553 (9:13-9:18, timestamp included)
For better #2 seek for highest refresh rate & frame rate possible with fastest GtG (ei. OLED). It reduces errors, latency and improves reaction times. It automatically improves clarity of #1 as well.

Great points! Example #1 you shared really lines up with what I’m looking for—motion clarity for pinpoint accuracy, target switching, and spotting quick-moving environmental details. It’s not just about tracking a single target for me. I often find myself scanning the surroundings fast to plan my next move, and that requires clarity across the entire frame.
I do agree that OLED’s response time is better, but I’m not convinced I’d notice a big enough difference compared to an already insanely fast TN panel like the XL2566X+. Plus, it has higher peak brightness and solid BFI, which is a huge factor for me. If the colors on the XL2566X+ are as improved as people have said—closer to what I’m used to with the XG2431—I think I’ll be more than happy with it.
In the end, I went with the Zowie because I’m chasing a real competitive edge. It’s not just about motion clarity (which I probably didn’t explain enough in my post); it’s also about Zowie’s features that improve visibility and consistency in FPS games. That’s exactly what I need to play my best.
If money wasn’t an issue, I’d probably go with the Asus PG27AQDP. But for now, the XL2566X+ just makes more sense for my setup, especially since I’ll be sticking with my RX 6800 XT for the next couple of years.

Updated Reasoning for Choosing the XL2566X+
After further reflection, I’ve solidified my decision to go with the XL2566X+, especially considering this is a display I’ll be using for the next 5+ years. The main deciding factor for me is how sample-and-hold blur—present on typical displays and even OLEDs without BFI—affects motion clarity.
Our eyes naturally perceive motion more clearly when images are displayed with flicker, as I’ve experienced firsthand with my CRT running at 105Hz. While OLED offers zero pixel ghosting and effectively no panel input lag, the sub-2ms response time of a 400Hz TN panel is negligible in comparison. In real-world usage, I doubt I’d even notice a difference in response time between the two.
The clear advantages of OLED, such as better colors and perfect pixel transitions, are appealing. But even with those benefits, sample-and-hold behavior still introduces blur, which BFI (like DyAc2 on the XL2566X+) can effectively eliminate. Additionally, the higher brightness of the TN panel is a huge pro in competitive settings—350 nits with BFI versus the OLED’s 250 nits. This added brightness ensures better visibility and contrast, which is critical during fast-paced gameplay. These factors combined reassure me that the XL2566X+ is the right choice for my needs.
I’m confident this decision will give me the motion clarity and consistency I prioritize for competitive gaming, even at the expense of OLED’s richer colors and zero ghosting.
I'll add a final comment to this post concluding if I've decided to keep the XL2566X+ once I have one in my hands... then I'll make a separate video review explaining my reasoning and panel experience.

i did the same thing early this year tried the zowie, the pg27aqn with ulmb, and the pg27aqdm
and to be honest
For FIRST PERSON SHOOTER Games, i see no point going with BFI.
For games like league of legends where you need to Track your whole Display it could be a advantage, but i see myself and other pros only moving their Camera, basically their eyes are 90% of the times on the crosshair, this explained why I didnt even feel a difference in Gaming Performance with ULMB 2 enabled and not, and this are basically 2 extreme scenarios, because ULMB 2 is the best Bfi out of all, was better than my xl2566k, and without BFI it was just a 360hz IPS, where an 360hz OLED is a Lot better
So I want to say, if I don’t even feel a difference in Gaming Performance between a 360hz IPS and 360hz ULMB 2, the difference between a 360hz/480hz OLED will be even less, however moving the Camera while staying with the eyes on a Car or house or some text Looks Insane with ulmb2, but there are exactly ZERO situations where u would do that in a competitive match. It’s all Marketing, atleast for FPS games
And i tested like Everything this year

And currently just my xg27acdng arrived, im staying with that until 4k 240hz in 27“ Monitors are coming out
I really liked the FO27q3, but unfortunately, it had some sleep standby issues where it wouldnt wake up
The XG27aqdmg was also really good, perfect stand, nice Color calibration from asus but the FO27Q3 had some slight edges, like hdmi 2.1 + 360hz instead of 240hz.
But the XG27ACDNG is basically Like a Fusion of those monitors, it’s a XG27aqdmg but with the 360hz QD OLED panel + HDMI 2.1
Perfect Monitor
Now this with a 4k Resolution + a RTX 5090, and you never need to switch monitors again

Discorz as always, thank you, very interesting.
I better understand now why i literally prefer Brute Fast Reponse Time (OLED | TN w/o strobing) over Strobing on games like Apex Legends.
Artifacts (crosstalk/overshoot) are the worst enemies of tracking intensive games.
I have never been able to stand strobing on monitors even with BlurBusterUtility and yet I hate ghosting to the core of my soul.
Because in reality I spend more time on tracking demanding games than flicking (Overwatch, COD, Apex Legends)

Can you compare xg27acdng and fo27q3, where each of them is better, like brightness, OSD (black EQ, gamma, sharpening etc) and color tuning? I had PG27AQN and since this model im afraid of ASUS monitors because this model was with ugly yellow tint (on high saturation), no sharpening option and really badly implemented black EQ. Would really like to hear your opinion, thanks.
