| Sorry. I made at least two errors on my post. "HDMI 1.2" should have been "HDMI 1.3" And my "60Hz" actually should have just been "progressive." You are correct, Jarle, that it will display different frame rates, as long as they're progressive. When I bought it, I was doing interlaced TV, and the converter was needed to see my work on the display. This is from the "Using w ProVideoApplications" PDF from HP. " However, due to the architecture of the “front end” electronics used in the HP DreamColor LP2480zx, the color gamut remapping circuitry will be bypassed if the following conditions exist:  The monitor is fed a YCBCR (digital) or YPBPR (analog) signal. These signals must be color-space converted to RGB.  The monitor is fed an interlaced or 1080-line progressive segmented frame (PsF) formatted signal (for example, 1080PsF/23.976). These signals must be converted to true progressive signals via a converter box. Using the HP DreamColor LP2480zx for professional video applications 3  The monitor is fed an analog signal via the composite, component or S-Video inputs. These signals must be converted to an RGB progressive signal and input via one of the digital inputs, such as HDMI. When a video source that meets one or more of the above criteria is sent directly to the LP2480zx, a warning will be displayed onscreen and the color space presets will be disabled in the On Screen Display (OSD) menu indicating that they cannot be selected. In this mode, the monitor is operating in its “native” mode, at the full panel gamut and with no tone response, gamma, or other corrections applied. The resulting image will typically be highly saturated and will not match the expected levels.
