ViewSonicPX701-4K UHD 4K Projector with 3200 Lumens, 240Hz, 4.2ms, HDR, Auto Keystone, Dual HDMI 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.

I love the Key Stone on this projector. Ok, that sounds like a strange thing to start with, but have you ever wanted to try to project on a curved screen? Ya, like I said a strange want... It's very cool!!! Now on to the things you want to hear... It is a very bright projector, and it has a very crisp image. Yes, it works well for 3D using Blue-Ray. Streaming 3D is hit or miss (I'm not sure that is the fault of the projector). I find the colors to look good and HDR10 seems fine. For the price point this can not be beat. I have no review on the auto keystone, I’ve never tried it. Lol

1/30/23Projector stopped working after a year and a half. Contacted Viewsonic and was approved for RMA and was informed that the bulb went bad. It’s a pretty good projector, but the bulb didn't last 20,000 hours in SuperEco mode as advertised. The bulb warranty is only for 1 year and cost ~$200 if you purchase a bulb through them. I decided to purchase a lamp from a third party and just had them return the projector without a working lamp.3/7/23Projector came in, i replaced the lamp and after turning it on I noticed that the image was warped in the middle and had to send it back to them for another RMA.3/23/23Projector came back and projected a perfect rectangle image out of the box. However, I noticed that the zoom knob was turned all the way to the left(when facing the projector upright) which projected a smaller image. After testing the zoom setting, I noticed that the device was only able to project a perfect rectangle shaped image when the zoom knob is adjusted to show the smallest image up to right dead in the middle. Shifting the zoom knob beyond the middle showed warping at the top center of projected image. I contacted Customer support to report my findings and was issued a replacement. And it comes with a bulb!4/7/23Projector came in and is running great again. Projected image is a perfect rectangle from the lowest to the highest settings using the zoom knob. It did come with a new lamp, hopefully this one lasts 20,000 hrs as advertised.Overall, it’s a solid projector from a solid company. The projector is bright, has low latency and high fresh rate. Perfect for gaming, watching movies or even using it as a PC monitor. Only downside was the bulb that came with my projector did not last as long as it was advertised. Customer support was great and responded in a timely fashion.

Setting it up was quick and easy, and the range of connectivity options means I can plug in all my devices without hassle.The size and clarity of the image make it feel like I’m in a theater every time I use it. Whether you’re watching a blockbuster or just streaming your favorite show, this projector delivers. If you're looking to ditch your TV and upgrade to something truly cinematic, this is the way to go!
