    Has anyone experienced the same problem ? ( Unable to set Full RGB Range)

    I have recently sent emails to Intel driver team and no responses at all.

    Post this in Lenovo's forum. They are typically very good about sending user feedback on issues to engineering.

    RGB Full Range is enabled via my EIZO EV2334 OSD. However, Intel Control Panel is unable to recognize the RGB Full Range as the correct color space.

    Is it possible to change from limited to full on that Intel Control Panel page?

    Nope. because this function is still not working. ( In fact, you will see the whiter screen when RGB full range is enabled )

    Quote from recent review of Intel Sandy Bridge

    Several new features were added to Intel’s graphics settings utility including “Quantization Range” which controls levels (16-235 or 0-255), “Total Color Correction” and “Skin Tone Correction” Still missing however, is an obvious way to change SNB’s RGB 4:4:4 8-bit output to any YCbCr variant or utilize greater bit depth when connecting to a display able to take advantage of those features. That said, checking the option to enable “xvYCC” support actually does change the output to YCbCr, but either due to driver issues or player support changing to this mode negatively impacts video levels, annihilating any black level detail. Ideally these options will be segmented in future driver releases enabling end users the flexibility to chose the correct color format and bit depth for their display and calibration.

    Quantization Range Problem still remains unresolved.
