What customers say about "Key Specs"
ViewSonic PJD7720HD 1080p Home Theater Projector
  • Bright, bright image. If you are thinking outdoor movies like I am, this one is a winner due to the brightness.
  • Great picture. I went straight for the good stuff and queued up some 1080P NFL videos. I wanted to see how fine the details looked when projected large, and I was certainly impressed.
  • The resolution, contrast, and brightness are excellent. This makes a great projector for a large room.
  • Resolution is also impeccable. You will see every iota of detail from your 1080p image sources.
  • However if you have a smaller room (under 12ft) move along and buy a short throw projector.
  • Crisp and Bright, definetly worth the dollar. Seems to flicker in SuperEco, but runs fine in Eco. Will update as time goes on.
Optoma HD142X 1080p Home Theater Projector
  • I bought this unit because it offered outstanding viewing qualities - high brightness resolution, high video and graphic's resolution, good pricing and portability.
  • The vast array of options and features make this one of the best, if not, the best budget home theatre projector with a full 1080p native resolution.
  • Excellent color reproduction , mamboing contrast , do very well in dark scenes.
  • One of the reasons I went with this model was because of the higher brightness rating. I have it in my living room which has blinds over the windows, but theres still a decent amount of ambient light in the room in the middle of the afternoon.
  • Rainbows are everywhere in high contrast scenes like credits on black background, my older DLP has none compared to this one.

What customers say about "Display"
ViewSonic PJD7720HD 1080p Home Theater Projector
  • I Chose this as my projector for my budget given a few reasons being it is capable of great color saturation, 1080p full HD/3D with active glasses and 3D content, and it's moderately light weight.
  • At a throw distance of about 10 feet, it looks amazing even with the sun shining in
  • At normal viewing distances, you will not see much in the way of screen-door effect, perhaps only on the brightest material.
  • Although, this projector performs well in my preferred specifications I did notice a moderate Rainbow Color Effect that is common with DLP projectors in this price range, the color wheel and lamp can create this effect, I found it noticeable every now and then but not irratating or annoying
  • Another undesirable factor of this projector is the lamp life can drain quick if left unattended, given the DLP lamp is good for about 2 years or less before in need of replacement.
Optoma HD142X 1080p Home Theater Projector
  • I have it at a fairly good distance and its projecting a huge crip and color rich picture. Setup was super easy.
  • It does have 60 frames per second and also a great picture for gaming or watching movies and shows
  • I had been looking for a projector for awhile. The picture looks great on my 100" 16:9 screen. I'm glad I purchased it.
  • Image in bright even scenes in uneven, but not that noticeable on other scenes.
  • Not enough zoom for bedroom use. Image size does not gets to THX recommended 40 degrees viewing angle.

What customers say about "Features"
ViewSonic PJD7720HD 1080p Home Theater Projector
  • You can hear the speakers pretty well indoors, but don't expect too much.
  • The 10w onboard speaker is pretty powerful, considering.
  • The fan noise is commendably low - in Eco mode, I could barely hear it, even when sitting next to the projector.
  • NO ZOOM (Need a lot of space for a decent size screen)
  • This would be a 5 star product if it had a zoom dial.
  • The fan is still very noisy. And the onboard speaker resets to "on" every time I use it which is very annoying.
Optoma HD142X 1080p Home Theater Projector
  • longer lamp life of 8000 hour compared to about 5000 average on others
  • I especially like that the projector has a USB port so that I can power my Amazon Fire stick directly from the projector.
  • Decent speaker on it can be used occasionally but would need better speaker if watching movies
  • The internal speaker is not the greatest. Voice sound clear and loud but anything else is bad, external speaker strongly recommended.
  • Also the speaker is not great & I think the could've threw in some type of stand or mount but maybe I'm asking for too much now.

What customers say about "Connectivity"
ViewSonic PJD7720HD 1080p Home Theater Projector
  • There are two HDMI inputs, but one is concealed in a side compartment. This compartment is similar to the one on the PRO7827HD, but it lacks the micro USB power cable. So it might work for a streaming stick, but you're going to need a heck of a USB cable to power it.
  • Will need to purchase an HDMI cable separately
Optoma HD142X 1080p Home Theater Projector
  • USB power is a must have for chromecast, amazon fire, or other usb peripherals
  • It has a USB port to power up firestick
  • Only 2 HDMI and no other inputs
  • Only 2 HDMI ports and 2 audio ports. I wish they had included a few more ports.
