I have a media company and we often will setup projectors for our clients. The most important aspect of any project is expectation. If we set expectations correctly for our customers, and we meet or exceed those expectations, our customers are very happy. This is a true native 1080P projector for under $300, so you need to set your expectations for that of a projector that costs less than $300. If you are expecting the performance of a much more expensive native 1080P projector you will be disappointed.
With that out of the way I will give you my opinion of the Vankyo V630 Projector, and this is based on my experience with many home and commercial projectors. When I first saw a projector that was native 1080P at this price point, I thought it was a misprint. These projectors usually start at $700 and go up from there. You can find sales for less, but still, considerably more expensive than the Vankyo. I decided to purchase one and see how it performed. I will tell you that this projector is rated at 6000 Lux, NOT 6000 Lumens! In my opinion, this is a big mistake, and it works against a company by setting the wrong expectation. Most people will not know the difference between Lux and Lumens and when they see the picture a projector with 6000 Lumens and then a projector that is rated at 6000 Lux, they will be an extremely disappointed and unhappy customer. A quick and simplified explanation of Lux as compared to Lumens is that Lumens never change. This is the brightness level of the projector. Lux on the other hand is a brightness level on a specific area and can change depending on the size of the area. Just understand that projectors should always be rated at Lumens and no Lux.
Based on a complicated conversion equation, this projector is approximately 1200 Lumens. Plenty bright for a dim lit or dark room, but not bright enough for a well lit or sun bright room. The picture quality is very crisp and good quality, definitely good enough for a movie night inside or at night in the back yard. It is also great for gaming. I connected my PS4 and was amazed by the picture for such an inexpensive projector. The Vankyo 630 is very portable and will work great as a travel projector. It is very light and comes with a very nice storage case. The speaker is also very good. It is loud enough that you could set it up to watch a movie or play games and just use the audio from the projector, just don't expect full range audio like you would get from a sound bar with sub or digital sound system. The fan is not quiet, but it is not abnormally loud either. It should not be an issue unless you are sitting really close to the projector. I sat about 4 feet away while playing a game using the projector audio and did not have an issue.
This unit, unlike the V600 and V620 has digital Vertical and Horizontal keystone and it worked very well. There is also a manual vertical keystone dial and I found that it softened the focus when used. The digital worked much better and kept the picture in focus.
I gave this unit 5 stars based on the expectation of a $300 native 1080P projector. I found the picture very good and the bright enough for use in a dim lit or dark room. You will not be disappointed playing games or watching a movie with the Vankyo 630. If you don't want to spend a lot of money on a projector but would like a movie theater experience, I don't think you can go wrong with this projector.
