Question: I'm going to be mounting this projector on the ceiling, would you know what size of screws would fit into the nuts at the bottom of the projector
Document: At 5 pounds and compact enough to fit into many briefcases, Epson VS330 is the right size and weight for salesmen, traveling trainers, executives, more. Bright enough at 12 feet distance to display comfortably on a blank white wall in moderately lit room, this projector performs even without a screen (just in case you forgot to bring one).
Its native resolution is 1024x768 (4:3 ratio), but despite the loss of vertical resolution it puts out a fine 16x9 picture as well. The colors are very bright and the image size can be adjusted easily to fit the screen without fidgeting too much about the projection distance.
For home theater use one would want16:9 or 16:10 aspect and at the very least 720 resolution, with 1080being preferable.This is a light weight projector, clocking in at just a hair over 5lbs. It, the remote and various cords could probably be easily cartedaround from office to office if Epson had only seen fit to include acarry case or pouch.
For example, you could easily connect your laptop (either wired or via the wireless adapter that's included) to the projector and mirror your computer's display. The remote control is equipped for a number of functions that are useful for Powerpoint presentations, such as a pointer and the ability to freeze the screen.Although I do like this item, I'm not sure I would recommend this for a dedicated home theater setting.
I was also pleased to find it included both a monitor cable (VGA) and HDMI cable. It is very lightweight and compact with a lower profile than the others I viewed. I ceiling mounted the projector the day I received it and watched a movie streaming via VUDU. It has a perfectly clear and crisp image with no jitter or blurring during action scenes. I would highly recommend this projector!
We have truly loved having this compact projector in our home. Movie nights have become so much more fun since our screen size has increased from 32&#34; to the size of our whole wall. The picture is crisp and clear, even small print is legible.
I recently received this projector, and I put it through the paces - I tested it on a 70&#34; projection screen. The image quality and color is quite good. Of course, size and sharpness can be manually adjusted.Perhaps the most notable feature is the size and portability of the projector. It comes with a carrying/storage case that protects the unit and also includes a shoulder strap for easy transport.
For one, there is only one HDMI port - so if you wanted to attach more than one device (blu-ray player, streaming media box, gaming console, etc.) then you'll have to connect and disconnect each device every time you want to switch between them. Secondly, as good as the image is, I'm not sure it's equivalent to a 1080p HD projector (and this projector also does not have 3D capability).
However, many of my friends were satisfied and believed it was more than suitable for home use provided an additional sound solution was incorporated. This simple fact, combined with the price point, makes it a very attractive option without breaking the bank.In summation, the Epson VS330 is a solid entry point for home use (entertainment) and a great choice for travel/business needs. Home use application varies depending on key factors such as viewing distance and angle as well as projector distance to screen and screen size.
Carrying your documents or video files on your phonerather than on a computer is doable.Next I unplugged the HDMI &#34;out to TV&#34; cable from my A/V receiver fromthe flat screen and plugged it into the VS330. What an improvement!I know that it could be better if I had the proper home theaterversion of the projector, but even this one produced a beautifulpicture projected on my living room wall.
Answer: I do not know the answer to your question.  But, on the bottom of my projector is a toll free number to ask questions.  The number is 1-800-637-7661. Hope this helps.
