Xbox 360 Spring Update unknowns: VGA image quality improvement
It has come to our attention that Daily Tech discovered that not only does the Spring Update that crept in recently to your Xbox 360 sport the fixes officially listed in the update list, but also comes with a few overlooked improvements as well. According to Daily Tech, one improvement that may have been missed by some users was that image quality has improved on the Xbox 360 – over VGA.
Often the object of criticism for “washed out” finishes to images, the Xbox 360 rendered images in a slightly less vibrant manner that even average digital cameras were capable of on small LCD screens. The culprit was the technical divide on how the LDC TV and LCD monitor interprets black levels.
LCD TVs define the color black on a level of 7.5 IRE when properly calibrated. In contrast the LCD monitor, commonly used for computers, labels black as completely black, with a zero level. LCD TVs also inherited that property when accepting signals through the VGA port, since manufacturers believed that the VGA port would usually be connected to PCs.
So while connected through VGA, the Xbox 360 still sends signals appropriated for the 7.5 IRE level of black, instead of zero. This tells the LCD that the color isn’t actually black, but a lighter shade of grey. Thanks to the Spring Update, however, Xbox 360 owners have access to an IRE tweak feature that allows them to set the black level either to 7.5 IRE, zero IRE or and IRE level in-between.
The modes are Standard (zero), Intermediate and Expanded (7.5) modes are the only three modes that encompass a viewers range of options, although we believe once you go expanded, you won’t be going back to standard. Comparison images brought you by Daily Tech.
