The OSD Interface
Upon activating the PW191's on-screen control panel, users are greeted by a simple menu that's clearly labeled throughout the various sub-sections.
The first three menus are where users can tweak all of the settings that relate to image quality. On the first screen, a number of pre-set modes are available that affect the overall color temperature, brightness and contrast of the images being displayed on screen. The names of each of these pre-sets explains what they are best suited for - Scenery Mode, Standard Mode, Theater Mode, Game Mode, and Night Vision Mode. Personally, we found standard mode to offer acceptable performance for almost any scenario, but users who like to fine-tune their display will be pleased by the number of options offered by the PW191. Also note, that if none of the pre-set modes produce images to your liking, a custom user defined mode is also available, and each of the pre-sets can be altered manually as well.
The aptly named "Input Select" screen gives users the ability to do just that: select which input (DVI or VGA) is active. And on the System Setup menu, users can alter things like speaker volume, OSD (on-screen display) position, and language. Lastly, there is an option to reset the PW191 back to the manufacturer's defaults.
