BenQ XL2420T Calibration Settings?

post #1 of 9
Thread Starter 
After much deliberation I finally decided to take the plunge and opt for a 120Hz panel over an IPS. The monitor arrived and had zero dead pixels, and with some tweaking, decent colors - but I just cannot get the whites looking right. They're very washed out, to the point that the Lagom LCD test for white saturation fades out at about the 248 mark (maybe 249), but the entire bottom row is pure white. I've looked at profiles from Prad.de, TFT Central, and even a few user profiles, but they all suffer the same problem. Currently I'm running Standard mode, 2 Brightness, 25 Contrast, Gamma 4, Color temp Normal which is about the best I can get it to look, but it's still very washed out. Interestingly enough the profiles from Prad and TFT Central were worse (Standard mode, 5 Bright, 50 Contrast, Gamma 1/2, ~R96/~G99/~B95), they pushed back the white saturation test to around 247 as end visibility.

Does anyone else have this problem? Or has anyone else used the Lagom LCD test to help ensure their monitor is displaying things fairly appropriately? Granted I'd rather have the superior black levels (which this monitor does have compared to my old T220) for gaming over the white levels, but I'd still like to get them better if possible. Is there some goofy setting I missed, like some sort of backlight overdrive? Is this just a common problem that I haven't heard about somehow? Any advice would be appreciated here. I have tried turning down my contrast to zero and setting the color temperatures way down in the 50's and even 30's, but nothing can make that bottom row visible.

120Hz is awesome by the by. Reminds me of how smooth games were back in my Quake II/AvP/UT days on my CRT.

Well in the world of tvs, brightness controls black levels, and contrast controls white. Not sure with monitors.

Fiddling with the contrast doesn't really do much. I can make things a lot whiter (which doesn't help), but nothing will get it beyond where I want it to be.

Commenting to keep track as I have the same problem with my XL2420TX just not looking quite right. The ICC profile from TFTcentral made a huge difference, but it stills seems a bit...off.

There is a bit of a rundown of the OSD settings and how to set up the image in the calibration section of the pcmonitors.org review (http://pcmonitors.org/reviews/benq-xl2420t). This is specifically for AMD GPUs but it may also give Nvidia users some ideas. Nvidia GPUs output a less rich and vibrant image on the XL2420T and some users like to add a touch of 'digital vibrancy' to try to compensate. I would advise trying to set everything up through the OSD if possible rather than relying on any driver tweaks or ICC profiles (especially those created on another system and monitor).

dont know about u guys but i got a new 2420t and for some reason i can change some important setting like "gamma" "color" "hue" to name a few. They are just grayed out and not the normal "white" where i can click on them and change them. Have any of u heard of such a thing before?

I'm suing the video cable that came with the monitor and i have 2 evga gtx 285..The issue is not that im locked out of the OSD, a million people wrote hold any button and wait for 10 secs that does not fix it since its not the issue.

p.s. I was just wondering if the problem is that I have nothing native from the monitor installed but don’t get why that would not let me change “color temp” for ex.


Thanks,
Sebastian
