ViewSonic PX700HDH DLP 1080p Projector with 3700 Lumens, Supercolor, 1.1x Optical Zoom, 22000:1 Contrast Ratio, Dual HDMI, and Vertical Keystone for Home Theater

I wanted to add a review for using this as a computer monitor in case others were thinking of the same.The unit is very bright. I don't have to close my windows if I'm looking at high contrast things like text. Color isn't maybe as good as more expensive projectors, but I found it to be fine. I found that using 1080p resolution for desktop use was better than 4k as the pixels are a bit fuzzy at that resolution which makes text not look as good. This is due to the pixel shifting tech used (any 4k projector sub $1600-2000 will use this). The screen is very detailed at 4k showing movies and games, however, and the pixel shifting kind of adds a bit of an anti-aliasing effect. I dare say I might actually prefer a pixel shifting projector for computer use as it lets you decide between 4k 60hz and 240hz 1080p with both modes having their own strengths. I feel I have two monitors I like for different reasons which is cool. There is just a slight perceptible lag on 4k, but its really not bad. I don't notice any at 1080p 240hz. And it really does go that high, the difference between 120 and 240hz is noticeable, and it looks really good at the high refresh rate. I actually prefer it over my 144hz 1440p monitor. I don't think this would be good enough for esports compared to a 240hz monitor, but its very close. Remember to use the game mode.Overall it works better than I expected as a computer monitor and I'm happy with it and feel it was a good value for the money.Other thoughts-I wish the power plug was longer. I'm not going to install this in ceiling, and I had to use an extension cord for it to reach down to a plug that is only a few feet horizontally away.-The remote is a bit old fashioned looking. Not a big deal to me but I think ViewSonic should update the design.-Sometimes the unit makes a strange whirling sound that is annoying. Usually it doesn't and it has done it less as I have used it. Its not the fan, it sounds like something is spinning that is not lubricated. When this isn't happening I found the fan noise to be fairly low and constant.-Its very easy to switch between modes like normal and eco, needing only one button to be hit. This is really nice since the bulb has a lifespan. If I know I'm going to step away from the computer for a few minutes or am going to just be looking at text I can switch it to super eco in two seconds.-SuperEco at 240hz flickers, changing to a different refresh rate fixes this.Some tips:-Dynamic Eco is basically as good as normal in terms of color and brightness at least when its showing a bright image. That's my main setting. I think it just dims when the screen is dark. It is better than eco (but not super eco) in terms of bulb life according to the manual.-Make sure your resolution is 1920 by 1080 if you want 240hz. If its 1920 by 1200 if will default to 120hz.-if the projector is located above you, make sure you turn the projector upside down. It will need next to no keystone correction that way which keeps the image at native.

First things first, because there is no mention anywhere of 3D support in the specs or product description there are a lot of comments out there stating that the PX701-4K isn’t capable of 3D. This is incorrect. It does in fact support 3D and it looks great! The older versions that were initially shipped did not support 3D. However, since then ViewSonic has made the necessary hardware & firmware upgrades to correct this. Now that the 3D speculation is out of the way let me talk about the projector. It’s a great 4K projector considering the price tag. True, it’s not native 4K but it does produce 3840x2160 pixels when inputting a 4K signal into the projector. The projector does this. by what’s called “Pixel Shifting “. This is done to expand the native 1080p resolution to produce an effective 4K image on the screen. So, basically, you’re still getting 4K resolution without the much higher price tag you would pay for a native 4K projector. When you play 4K content the projector also displays 3840x2160 on it’s display on the screen. Another nice thing is that it supports HDR & HLG. However, it does not support Dolby Vision which is not a dealbreaker for me. The 3200 ANSI lumens produce a nice bright and vivid picture. I also really like the auto keystone feature. I have the projector sitting on a coffee table which is much lower than my screen and I didn’t have to adjust anything. The projector automatically adjusted the image perfectly. The fan is pretty quiet as well and If you have a surround system you won’t hear it at all. I haven’t tried gaming on it yet but if the specs are correct this should be great for gaming too! Overall I’m satisfied with the projector.

This would have been a 5 Stars projector if the first one I received was not defective.I was really impressed with the picture quality of this projector once I got it working. Which makes it a worthy replacement of my previous Mitsubishi DLP HD projector.Unfortunately, it was clear that I received a defective unit !!!!!!!!! This was clear to me within minutes of plugging in a 4K Apple TV unit as the source. I immediately heard a loud grinding sound. stopped everything unplugged everything and restarted... The same grinding started again. It was so loud and actually louder than my coffee beans grinder-No kidding!I removed the HDMI and connected a brand new 4K Apple TV that I had intended for this projector. It seemed to work fine and allowed me to adjust the image to my taste. A lot of control over color, picture quality. Overall excellent picture quality in 4k bright and detailed.On the first unit that was defective, there was somewhat a loud flickering sound -similar to an old 16mm projector running a film that was not as loud as the grinding sound I experienced with the first Apple TV I connected. It seemed really strange. When I pause the show, the sound stops, when I resume playing the show, the sound returns. I had to send it back and repurchase it again. I will update this review once I receive the replacement.Pros:-Super bright picture - that you can watch even with some daylight or soft dim light in the room.-High Quality picture-Beautiful colors-Smooth gradients and grayscales-Good on screen menu-Responsive remote (if you want the backlit version of this remote, it comes only with the PX 748 model)-Smooth zoom and focus ring for easy adjustment-Very Sharp picture from corner to corner-Auto Keystone feature - saves a lot of time and effort.-3 years warranty.Cons:Defective unit - makes ne worry about quality control***Update 12/15/22I received my PX-701 4K replacement! Very quiet fan which confirmed that the first one I received was defective! Stunning picture quality on a good quality 100" screen ! I attached several photos from Apple TV as the source with 100" electric motorized screen by Elite ScreensI do recommend this projector! It is a bargain for a 4K projector under $1000.***Update 12/28/2022. I'm truly in love with this projector, specially after testing 5 different projectors from different brands. In that $900 range, I haven't seen a single 4K capable projector that comes even close to this 3200 lumens brightness and picture quality. I highly recommend it!
