Using the automatic Iris technology which automatically dims and brightens the bulb depending on the lighting of the scene displayed, the 4900 can achieve a dynamic contrast ratio of 7500:1. The static contrast ratio is not specified by Mitsubishi, however it is at most 2000:1 which is the specs of the HC5000. Similar to the HC5000 the HC4900 bulb outputs 1000 lumens of brightness. One feature that Mitsubishi is promoting is the low noise output. When the HC4900 is on the low setting the fan sends out 19 decibels of sound, on normal operation the noise output is 24 decibels.
To aid in ease of installation the projector's lens can be shifted for minor adjustments in both the vertical and horizontal. The lens is attached to a motor control, which allows the shifting, zooming and focusing to be adjusted from the remote control.
It is unknown if the HC4900 features the Reon HQV video processing engine found in the HC5000.
