Review: Great for games! - I bought this about 5 months ago. I wanted a projector for a medium sized space, which I could play games at 4k, and watch movies, whilst also being able to switch between my PC and Nintendo Switch 2 (once it was released). I am more than happy with my purchase! Pros - - Can play 4k games - Large screen area (roughly 1.8x1.5m) - Can be mounted upside down. Cons - - Expensive - Fan noise is a little loud, but not overly so - 4k movies are not good to watch - the low Hz (60) makes them jittery Overall though, a fantastic buy! I would buy again if I was to relive the moment with my knowledge!

### ⭐⭐⭐⭐⭐ Works well as a computer monitor
*by A***W on 17 July 2021*

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.
