Windows 8.1 Pro 64-bit
nVidia GTX 590
Monitor firmware ver: 2 (woohoo!)
Using the DVI-D dual link cable.

After searching the net and stuffing around with menu settings trying to discover how to enable display mode sizes other than "Full" I dropped down to 120Hz from 144Hz and a slew of choices became available. I can't find anything that explains this in the manual. Incidentally, I'm using the "24" (16:9)" option at the moment... Text is blurry.

Is the Display Mode limitation at 144Hz a bug or is changing the aspect ratio and display size not meant to be allowed on the XL2720Z when running 144Hz?

Also, I noticed that before and after the firmware upgrade to v2 the Optimum Resolution as shown by this monitor is always 1920x1080@120Hz. The manual is no help here, either. My card supports 1920x1080@144Hz, I've been using 144Hz, and the monitor has shown the Current Resolution to be 1920x1080@144, but the Optimum is always "1920x1080@120". Why is this?

This is by design (not a bug).

144Hz pushes the processing limits of the monitor's electronics (and panel too), so some options available at 120Hz gets disabled at 144Hz. It's currently par for the course.

You can keep using 144Hz, it won't harm your monitor. However, all the monitor features performs better at 120Hz (e.g. better motion blur reduction during BENQ Blur Reduction at 120Hz, since there's more time for LCD pixels to finish GtG transitions between refreshes).

Stick to 144Hz if you want the lowest latency operation at 1920x1080. However, if the other features are more important, try 120Hz. Some people prefer strobed 120Hz as that has less motion blur than non-strobed 144Hz (photos: 60Hz vs 120Hz vs LightBoost)

hmmm... Then since the monitor processor is pushed to the limit at 144Hz, it makes sense that the extra processing power needed to scale down to other display mode sizes wouldn't be there. I think BenQ should let you write their bloody manuals.
