Both models have amazing image details and clarity for the price
excellent brightness and clarity
pixel-shift is incredibly effective and easily creates

projector required a bit of work to dial in
Pixel shifting tends to add some extra noise

ViewSonic PX747-4K - Pros & Cons

Both models have amazing image details and clarity for the price
excellent brightness and clarity
pixel-shift is incredibly effective and easily creates
brilliant blues and smooth gray tones
high quality and extremely powerful
and delivering varying levels of accuracy and flexibility
quality audio and video is shared and supported by his wife
tracking is almost perfect here
The sliders operate over a huge range and are very precise
motion is also very good
a decent colour performance and lovely sharp detailed images
Colours remain vivid and forceful
have very similar end goals and produce similar images
good brightness and very accurate colors
very sharp and clean picture
The backlit remote control feels pretty robust and premium in hand

projector required a bit of work to dial in
Pixel shifting tends to add some extra noise
Cinema room brightness is not as important as colour accuracy
Bright is not a good operating mode for video/film
play a lot of response-time dependent games
color brightness is only 45% of white on the PX747
the bulb is fading and the 720p resolution was never amazing
on a white wall with no screen frame
only small highlights are likely to show a problem
color does not change between SDR and HDR modes
hue error in magenta makes that shade a little too blue
primary colors are a bit less vivid
lack of contrast and black levels are not an issue
slight adjustments there were no issues of image artefacts
of them has particularly good black levels or shadow detail and contrast performance is also poor
these models are not designed for critical home cinema movie viewing to the standards
no lens cap or sliding door
mean the colours are bad just extra bright and maybe not as saturated
4K does not support reading from usb sticks or any external storage
no lens shifting which makes placement of the projector a bit more
lack of any kind of motion interpolation
clearest not the most pop image
images may look washed out compared to newer projectors
Too many are simply trying to capitalize on affiliate revenue
the fan ramps up just a bit too high to keep the lamp cool
ultra-short-throw projectors are more expensive to make
not have a lot of issues
the projector does tend to become a bit too hot at times
does make skin tones look a little rosy with on-screen material
