Rated 5 out of 5 by from Excellent Screen Adjustment Used this to replace an earlier version of an Epson. This updated model is just outstanding. It has a great feature that will auto adjust the screen to the size of your projector screen with minimal tweaking. Awesome!

Rated 5 out of 5 by from Great picture & easy set up I bought this projector a few months ago and just recently started using it. I'm glad I did research of many projectors as I needed one to project approximately 33 feet away. I was amazed at the clarity from both Blu-ray and satellite on my screen which is 16 feet high and 24 feet wide. The on-screen setup was extremely easy and had it going in a matter of minutes.

Rated 5 out of 5 by from EXCELLENT PRODUCT “This is a review for the Epson Powerlite 1781W Projector that I received free of charge to do a beta test and review." The Epson 1781W is a well rounded, thin-and-light projector, with good brightness and resolution, very good data and video image quality, and a wide range of connectivity choices. One of its few shortfalls is that as an LCD-based projector, it cannot project 3D content, which you can find in many portable WXGA data projectors such as the ViewSonic PJD6544w. But that only matters if you need to project in 3D. For its winning combination of features and performance at a reasonable price, the Epson PowerLite 1781W Wireless WXGA 3LCD Projector is our latest Editors' Choice ultra-light WXGA data projector.

Rated 4 out of 5 by from Review Of The PowerLite 1781W Wireless WXGA 3LCD Projector This is a review for the Epson Powerlite 1781W Projector that I received free of charge to do a beta test and review. I found this Epson Projector to be a definite asset of productivity. I am constantly doing presentations of all sorts, for my boss, for my employees, for potential clients, and I feel this device enables me to expediently do presentations like i’ve never done before. Why? First, the projector is super lightweight and really portable, its like a laptop more or less in terms of size and weight. I was able to fit it into my briefcase and it was a pleasure carrying it around, I actually couldnt believe i had a projector in my bag! It also really has excellent resolution and image quality. Just to try and see how good its resolution was, I tried projecting some extremely low resolution images (by design), and I could see with crystal clear quality the level of poor quality of these “test low resolution images.” So, I was impressed, to say the least. Another big selling pt is that this project is wireless, which allows me to connect to the projector from my smartphone, laptop, tablet, it doesnt matter, as long as the device can connect to Wifi, im good. I loved this b/c I hate messy cables and having to lug them around with me everywhere. This device eliminates the need for these messy cables. Finally, I thought this machine was just cool-looking. Like, I love devices, and having this machine makes me feel super nerdy and techy in the best possible way due to the fact that I love high tech, sleek, ultra cool tech devices. Why? They make my life more productive and fun! To be fair, I will say that the sound quality isnt up to par with the excellence of the machine overall, so, if you are going to be doing a media rich presentation where you will be using lots of video elements with sound, bring some extra speakers, thats what I did, didnt mind, had some portable Sony speakers already. But do be warned that the sound on this device isnt that good. Also, I didnt like that the machine got a little too hot, and, being the Nervous Nellie that I tend to be, didnt like this fact. I didnt like that the machine got a little too hot for my tastes/comfort. Nevertheless, I will say that this device definitely exceeded my expectations, and its small drawbacks are greatly outweighed by its top notch craftsmanship, excellent image quality, superb size/weight, and overall coolness factor.

Rated 5 out of 5 by from Superb Projector, Excellent Image This is a review for the Epson Powerlite 1781W Projector that I received free of charge to do a beta test and review. This is my first projector and I cannot be more impressed. The size is perfect to for taking from place to place (just a little thicker than your average laptop). The projector was easy to setup and I was up and running in minutes. Image quality is superb and the wireless function is one of the best features if this projector, sharing my phone/tablet screen was simple and there was almost no delay between my tablet and what was being displayed. An external speaker is a good idea but not necessary. I will definitely recommend this projector to my colleagues for anyone looking for new or an upgraded experience.

It is very light and compact. Perfect for travelling to do presentations and meetings. Bigger and small settings I think it will be fine. Good resolution and clear images. It is great in my experience using Power Point presentations. I would definitely recommend this Epson Powerlite 1781W Projector to everyone. I think it is worth buying and this is just amazing projector

Rated 4 out of 5 by from Crystal clear image! Extreme lightweight! This is a review for the Epson Powerlite 1781W Projector that I received free of charge to do a beta test and review. I'm just recently received this Epson projector and stray away from the unboxing you can tell very clearly what differentiates this projector from the rest. It is very carefully and properly packed to ensure Safety and Security until it reaches the consumer. Setting up his projector was a true breeze. Firstly it comes with just about every single connector cable that you could possibly need in order to project whatever you need from whatever device you need. Plugging it in and getting it setup projecting my computer screen took about 45 seconds. The projector automatically scans all the input ports and automatically detects the correct source. Then it automatically adjust to whatever projection screen or wall that you have set up. It Auto adjust the angle and Keystone by detecting the surface and making it basically plug-and-play. The quality is crystal clear, and I really like the fact that I can adjust the focus if it needs fine-tuning from both the remote and the projector itself. Once we're on the top of the remote, just about every feature can be done from both the remote and from the projector itself. The projector comes a built-in adjustable stand to help project it at the perfect angle. It also has a easy shrink / enlarge feature to make it to the correct screen size. Another amazing feature that this projector has is it extreme easiness to connect to. You could connect it from either your computer or your network or even directly from your phone with their very easy to set up app. You can even connect it directly to your wireless network and projected wirelessly that way as well. To go back to the app Feature for a second, it allows you to project a mirror image of your screen enabling you to have the flexibility of projecting from whatever device you need. All in all this is a extremely solid and reliable projector that can provide for all your needs in every setting with its extreme lightweight, small size, and quietness. It even comes with a very convenient travel bag that holds all the necessary wires and remotes and makes it very easy to take it on the go.
