Hello everybody,

I hope this dont come off as a lazy question but I was wondering If someone could point me in the right direction in setting up CRU for a 180 fps 1728 x 1080 resolution on the Zowie XL2566K . Should I just use the ToastyX CRU Vertical Total Calculator for Quick Frame Transport (QFT) as in viewtopic.php?t=10402 and call it a day? I am a noob to CRU. If the ToastyX CRU Vertical Total Calculator for Quick Frame Transport (QFT) is not the answer; can someone please give me a example of the data I can use when I put the timing on Manual for a 180 fps 1728 x 1080 resolution?

Is it a no brainer now to get the Asus 360Hz PG27AQN over the 66K?

Better response times - ULMB2 superior over dyac... And more important you can play on 25" instead of being stuck with 27"

I almost ordered the benq this week lol

I have the XL2566K I dont really feel the need to sell it and buy a ULMB2 monitor. Optimumtech says in the ULMB2 video he did not really noticed a difference between the OLED 240 HZ and the AQN. so he keeps maining the OLED.
The only monitor that I see worth upgrading now for sure is a 360hz OLED panel with ULMB2 from what I understood chances are slim we gonna see that monitor anytime soon.

Asus 360Hz PG27AQN costs almost double though. am i wrong? i bet the difference is negligible.

yeah its even more then double in W Europe. In the Netherlands and Germany its arround 1400-1600 euro. The AQN looks better with 1440P sure but 800-1000 euro better?

I just got this monitor. Hope it's a faulty unit, because I'm completely disapointed. My old Alienware aw2521hf performs far better in all terms at 240hz than this one at 360hz. At 60hz, I never had a screen, even in the 2000s, which looked so poor (I even include the awuful PSP screen). I could expect motion blur, but I have never seen in my hole life the image doubled both in front and back of the current frame, creating a sluggy effect which, if gaming, just makes the game unplayable. I could tolerate that if the monitor was a jewel at 240hz or 360hz, but side by side, I even prefer the aw2521hf even at only 120hz.

It could not be true that at 360hz + DYAC mode was performing less than a 60hz monitor I had side by side. And that was exactly the issue: the multi monitor configuration. Despite the monitor was at 360hz, the FPS were 60. As soon as I desconnected the 60hz screen, the UFO test started to run ultra smooth.

As a personal recommendation; only buy this screen if you are going to use DYAC in games and your PC can handle 240+ solid FPS.

DYAC + 60FPS = Run away (despite this was not supported, seems that this mode is now possible)
DYAC + 120FPS = No
DYAC + 144FPS = Meh (a no for mee)
DYAC + 240FPS = Yes, quite acceptable
DYAC + 360FPS = Amazing, you can even read the text while scrolling like on a classic CRT. Now, let´s find the game allowing that.

Remember framerate=Hz

You need to intentionally lower your refresh rate to 144Hz to make it look good.

Yep, 360fps 360Hz looks amazing.

But... 360fps is hard for GPUs.

HOWTO: Properly Using DyAc+ as a CRT Replacement

Here's a tip: If your priority is CRT-look over latency:

144fps 144Hz DyAc+ looks much better than 200fps 360Hz DyAc+

Try It. Lowering Refresh Rate Can Improve Strobe Quality If Easier To Get Framerate=Hz

- Good for solo games where lag isn't as important
- Good for more accurate CRT simulation
- Good for lower end GPUs
- Good for RTX raytracing and pathtracing
- Looks Much Better Than 360Hz when your frame rates are extremely low

360Hz strobe capable display can be a defacto luxury 120Hz-240Hz CRT, there's less strobe crosstalk.

DyAc+ even looks better at low refresh rates such as 100Hz-144Hz VSYNC ON than 360Hz VSYNC OFF. No double images at framerate=Hz. 120fps+120Hz on 360Hz panels look better quality than 120fps+120Hz on 120Hz panels, which is why it looks so amazing.

Lowering Refresh Rate Reduces Number Of Duplicate Images At Low Frame Rates

Image

That's why lowering refresh rate to match frame rate can improve DyAc+!

144fps 144Hz DyAc+ looks MUCH better than 144fps 360Hz DyAc.

CRT Motion Quality Tip: Framerate = Refreshrate = Stroberate

But to make it look better than "low framerates at 360Hz", please use a low latency framerate=Hz sync technology to get the proper "CRT experience"

Low Latency framerate=Hz technologies

- VSYNC ON + NULL (easiest)
- Low-Lag VSYNC HOWTO (harder)
- RTSS Scanline Sync (if you can do framerate=Hz at 50% GPU)
- Special K Latent Sync (if you can do framerate=Hz at 50% GPU)

360Hz is lower lag, but 100fps 100Hz DyAc+ looks better in "RTX ON" + "DLSS 3.0" solo games

Yes, 360fps 360Hz is better, but you can't always get 360fps sadly. That's a pain; especially because in fancy solo games, an "RTX ON" + "CRT motion quality" requires you to intentionally lower your refresh rate, for RTX ON to look like CRT motion clarity.

DyAc+ can strobe as low as 100Hz, and you can use an RTX 4000 series with DLSS 3.0 to get 100fps raytraced content in some games like Cyberpunk 2077 -- or other graphically intensive games that you would normally play solo.

If you want DyAc+ to look like a CRT at lower frame rates YOU MUST LOWER REFRESH RATE OR IT WONT LOOK LIKE A PROPER CRT.

The RTX and DLSS goodness in astoundingly beautiful solo games often adds ~50-100ms lag anyway, and the lag difference of 100Hz vs 360Hz is less than a 10ms difference (Math: Not all pixels refresh at the same time, www.blurbusters.com/scanout -- so the screen center scanout halftime of 100Hz is 0.5/100sec = 5ms, and screen center scanout halftime of 0.5/360sec = 1.4ms. The difference of 100Hz DyAc+ versus 360Hz+ DyAc+ is (5ms-1.4ms) = 3.6ms latency difference. That is only a tiny lag increase for a massive CRT motion clarity improvement!, and you should intentionally lower your refresh rate to match your frame rate, to improve CRT motion clarity, for your solo games where latency is not important.

Bring the refresh rate closer to your real-world-frame rate (Very Important!). There can be more flicker, which is a problem if you are flicker sensitive, but if you loved CRTs back in the day, then you should know that framerate=Hz becomes "CRT god mode", and you sometimes have to lower refresh rate to match frame rate.

It's necessary to improve quality by lowering refresh rate to properly simulate a 100Hz or 120Hz or 144Hz CRT tube, you're doing it wrong if you're CRT-motion-clarity priority over input latency. (Yes, 360Hz is lower lag, but why use 360Hz if you're playing Cyberpunk 2077 with DLSS 3.0? Lag ain't as important as CS:GO or other esports situations, if you are just enjoying a plain solo game. So, fix your settings it so Cyberpunk looks like a proper CRT. Otherwise you're incorrectly simulating a CRT)

DyAc+ supports custom Hz in ~0.001 Hz increments from 100.000 Hz through 360.000 Hz, via Custom Resolution in NVIDIA Control Panel, or via www.monitortests.com ToastyX (for AMD and Intel).

The experience I'm getting with this monitor is different. To test the best combinatios I usually run old games like Half Life or Quake 3 an move sideways on a corridor, or look at a corner, and move de mouse. The textures of these games are not bad to test motion blur, and the angled corners and corridors to test stuttering.

At 240hz, 144hz and 120hz (all DYAC+ and VSYNC ON) I get a consistent micro stuttering. I also experience it without DYAC, but it's less noticeable (slightly blurry on dark textures, but I have to say the monitor does a great job even without DYAC, being the top 1 screen I have tried in this aspect).

The only combination I did not get stuttering at all was at 360hz with or without DYAC+, even when getting 260 fps.
