ViewSonic PS750W Interactive Projector Review – Picture and Sound Quality: Color Modes, Video Image Quality, Text and Presentation Quality, Sound Quality

Color Modes

The color of the ViewSonic PS750W, right out of the box, is pretty good! Even the brightest mode, aptly named, “Brightest,” isn’t half bad. True, it does have the standard strong greens and yellows associated with brightest modes, but it is more desaturated than some of the others I’ve seen, which are positively ghastly. Brightest Mode should be considered your “break glass in case of emergency” mode that is only used when there is a lot of uncontrollable ambient light. That’s the first image in the slider above. You may notice that the image appears to have a grid or looks as though it has large pixels – it doesn’t. That is merely a reaction between the camera and the projection, and looks smooth in real life.

Dynamic Mode is leagues better, though the colors are still a tad muddy and off. You don’t really get great color until Standard Mode, which is actually the second brightest mode. This is the mode I decided on for taking the following photos in, as it was the brightest mode that had the best color. In classrooms, ambient light is a huge issue, so I thought Standard is the mode that will most likely be used. The next two modes, sRGB and Movie, also have good color, but Standard just has a lot more pop and “wow” factor as compared to the others.

Video Image Quality

Video image quality is good! It does depend, of course, on the quality of the video being projected. The photos taken from Journey to Space on Blu-ray look considerably better than the images of the Ted Talks, but Seth Godin looks nice and sharp (figuratively and literally) in his video course on freelancing. I was really blown away while capturing the photos from Journey to Space. The resolution on the ViewSonic PS750W is WXGA (1280 x 800), which isn’t as good as 1080p (1920 x 1080) or the business equivalent, WUXGA, but that didn’t matter in the case of this film. Everything looked as smooth and sharp as one would hope.

Check out the images in the slider above, and you’ll see what I’m talking about. In any case, whatever video the teacher is projecting, whether it be a documentary, film, YouTube videos, or other online teaching material, the PS750W is going to be plenty sharp for a classroom setting. I’d recommend for a K-12 school district, and even some colleges, provided their applications do not require ultra high resolution such as is the case with architecture, medical, and engineering classes where their renderings need to be crystal clear. For all others, consider the PS750W to have great picture quality when it comes to projecting video.

Text and Presentation Quality

Text and presentations look good. The text is sharp and readable, even at 8 point font. Granted, students in the back of the room may have a difficult time reading font that small, but no teacher presents content at that size. If you look at our test image – the first image in the slider above – you’ll see that the normal size fonts (12pt and 14pt) are clear and easy to read. Students should be able to read that from the back of the room, no problem, unless they have a vision issue – in that case, they should sit in the front of the class anyway. That the text looks good is a major plus, but what about the slides of presentations and infographics? All pretty great. The graphics are sharp and smooth, and really do look quite excellent.

Sound Quality

This projector is capable of producing some impressive sound! Those two 10-watt speakers go a long way. I was on the phone with Art while setting up this projector, and the Auto Power On detected my Playstation 4, which sent me scrambling to find the remote to turn down the volume so I could hear him speak. And the volume wasn’t even all the way up! That said, this projector would be suitable for even the larger size classrooms in K-12 school districts, though I wouldn’t recommend it for a lecture hall without first pairing it with external speakers. Those at the back would likely have a hard time.

ViewSonic has added enhanced audio settings for tweaking the sound to fit specific needs – those are Entertainment and Speech. Both fine tune the audio for optimal sound quality as it pertains to each category. It did make a difference to use this feature! Though, nothing will help the lack of bass in these built-in speakers they put in projectors. That’s normal, even in home theater, that the internal speakers are lacking in the lower frequencies. Oh well – it’s not bad at all. Good job ViewSonic!
