Blur Busters Forums

I just purchased a manufacturer refurbished Benq XL2420z from buydig (it is currently on the mail and will arrive soon) after learning it has the best color reproduction on current 144hz monitors.

I am currently using a 20" Dell 2007WFP Ultrasharp which is an 1680x1050 S-IPS 60Hz monitor.

my aims for XL2420z:
-achieve the best possible motion clarity with the minimum possible ghosting/artifact.
-use the blue light reduction feature (the highest setting: 10)
-calibrate the monitor using either ICC profile or through monitor's built in OSD.
-use very low brightness (probably about 15-25%)


I need help with:
-settings should I use (AMA, blur reduction, FPS1/Standard, etc...)
-settings on CRU and strobe utility
-I do not have a calibrator so where can I find color calibrated settings with maximum Low blue light reduction setting at 120hz vt1350?
-is it possible to do downsampling with this monitor (like 2560x1440 on 120hz with all the tweaks?) https://www.youtube.com/watch?v=hTszNDyuAhg

That said, be prepared for the switch from IPS to TN. The high refresh rate will be a big jump upwards in motion quality.

It sounds like you are trying to avoid eyestrain. Keep in mind you will have to make a decision whether you want to use strobing.

For Blur Reduction, it depends on the person. Blur Reduction adds refresh-synchronized flicker in order to reduce motion blur. View http://www.testufo.com/photo while turning on BENQ Blur Reduction.

Sometimes strobing reduces eyestrain (if you get headaches/strain from ghosting/motion blur) and
Sometimes strobing increases eyestrain (if you get headaches from PWM dimming strobe).
From hundreds of LightBoost reports, it can go both ways.

For adjusting brightness:
If you use strobing (BENQ Blur Reduction), lowering "Persistence" can get you a dimmer picture than Brightness 0%
If you don't use strobing (PWM-free mode), then Brightness 0% thru 25% can be good if you're sensitive to bright screens.

For adjusting AMA, leave AMA untouched when enabling BENQ Blur Reduction. If you don't use Blur Reduction, most people use AMA High. The FPS modes don't seem to support Low Blue Light, so you will want to re-optimize the other modes

See the Blur Busters Strobe Utility page for the ideal settings. Usually it's Crosstalk close to 0, and Persistence set to user preference. Brighter versus clearer depends on the user and ambient light.

pcmonitors has .icc files avaialble for download for the XL2420Z:

Many 120Hz+ users reduce detail to keep framerates high, to improve motion quality (motion fluidity)
instead of static image quality. Currently, not many of us use downsampling around here. But downsampling works if you use GPU scaling. Using ToastyX Pixel Clock Patcher can help.

However, you want triple-digit framerates to get maximum benefits of a 120Hz+ monitor, and using downsampling will prevent you from being able to get these framerates. As a result, downsampling technique is not usually recommended for 120Hz+ operation.

I have just changed to the exact same setting rcarlos has. My problem is that I've had the Dell 2007WFP (S-PVA) for a while and lost its calibration file (icc) a long time ago. I didn't really miss it that much as I managed to get an image that was decent enough compared to the profile I had, but now, with a properly calibrated XL2420z beside it (kinda, as the XL's side keys get in the way of keeping monitors right next to it) the difference is just too much to ignore. I had been getting the feeling that my 2007WFP image quality had deteriorated lately (feel its losing brightness and its colors are getting red-ish) so if its not psychological that might be a reason.

Does anyone have a 2007WFP ICC profile they could share? I've searched and searched but couldn't find where I got mine. Actually I couldn't find a single profile for that monitor which I didn't expect given its popularity on the late 2000's.
