Google "LightBoost" now

BTW, a good calibration for the VG248QE is to lower your Contrast to 65, which brings the color back. It does look somewhat darker. In addition, use a LightBoost=50% setting, for the improved motion clarity, though I raise it to 100% during the daytime when the room is too bright. The monitor's controls are locked because of the need for precision pixel transition control needed for the stroboscopic backlight. I also calibrate using nVidia Control Panel using the [url=http://www.lagom.nl/lcd-test/contrast.php]Lagom LCD Contrast pattern[/url], as well as [url=http://www.lagom.nl/lcd-test/black.php]Lagom Black Level[/url]. Alternatively, getting a colorimeter (e.g. Spyder4) makes it massively easier to recalibrate the picture without needing access to your monitor's original controls. TFTCentral got nearly all of the original color quality back, while keeping LightBoost enabled.

So, Marc, does that mean you canned your project in favor of lightboost monitors? I hope not....

It's just shelved for now; I haven't cancelled my homebrew project (Found at [url]http://www.blurbusters.com/category/homebrew[/url] ...) I will say that I have subsequently discovered that stroboscopic backlights significantly outperform scanning backlights, for many reasons (e.g. zero backlight diffusion issues). This does, however, bring in some new technical challenges that may also require me to modify existing LightBoost panels for better image quality. One of the many options I am considering for later in 2013, is a modified variation is I may debezel a monitor, carefully hack the edgelight to replace a LightBoost edgelight with a much brighter edgelight (utilizing fuller spectrum LED's, or even RGB LED's) and utilize much brighter and shorter strobe lengths (e.g. 0.5 milliseconds) for even better motion clarity, running off the existing LightBoost electronics & the existing strobe-optimized response-time-compensation logic built into the LCD panel. This could be a bulky edgelight contraption, hanging off the top and bottom edges of panels, focussed into where the former edgelights were; as I'd use massively brighter LED's to compensate for the shorter strobe lengths. Right now, finishing the Blur Busters Motion Tests project (see [url]http://www.blurbusters.com/motion-tests[/url] ...) is a much higher priority :-)
