What to Pay Attention To in a Home Theater Projector

Purchasing a property theater projector can look daunting. At any given time, you’ll find several models to select from, each with its personal special advantages and downsides and every single proclaiming itself to be the “right” one particular. The essential to simplifying the approach is determining what you will need and then locating projectors that match your criteria.

Most projectors display images based on either DLP (digital light processing) or LCD (liquid crystal display) technologies. While both sorts of projectors function sharp image top quality and correct colour representation, each has its personal positive aspects.

DLP advantages:
Permits for any lightweight and compact projector (specifically for pico models)
Portrays a film-like picture from DVD, Blu-ray and HDTV sources
Smooth motion for videos and fast-action scenes
Deeper, truer blacks than LCD projectors
High colour contrast
3-chip DLP on premium models supplies even greater image high quality

LCD advantages:
Brighter output for use in well-lit rooms
Impressive color brightness
Sharper pictures for detailed graphs and data presentations
Vibrant 3D photos with no image ghosting
A lot more power effective than DLP projectors
Slightly quieter than DLP projectors
Most LCD projectors contain 3-chip LCD technology (3LCD) for even higher image good quality

LCoS (liquid crystal on silicone) is actually a third type of projector technology, typically accessible only on high-end models. These types of projectors provide a mixture on the benefits of DLP and LCD projectors, which includes a bright display, smooth video, and impressive color saturation.


The number of pixels around the imaging chip measured from side to side and top to bottom. Nearly all high-definition projectors created for home theater use are Full HD 1080p – 1920 x 1080 pixels. You’ll find now a couple 4K Ultra HD projectors with 4096 x 2160-pixel resolution – more than four occasions the detail of HD. The larger the resolution the smaller sized each and every pixel will seem, generating pictures that look much more seamless, with significantly less noticeable “pixel structure.”


House theater projectors typically have brightness ratings of 700-2500 lumens. All projectors have plenty of brightness for watching movies in a dimly-lit or darkened area. A higher brightness rating will are available in handy for viewing when there’s far more ambient room light. It really is also helpful if you’re projecting onto a wall (it really is much less reflective than a screen), or if you are displaying an extra-large image (110″ or bigger).

Throw Ratio, Lens Shift, and Keystone

The throw ratio tells you how wide the image will be if you spot the projector at a particular distance in the screen. For example, a 1.8:1 ratio will create a 5-foot wide image whenever you location the projector 9 feet in the screen (five feet x 1.8).

Calculating the throw ratio is especially critical should you program to permanently mount the projector. Should you cannot install the projector far enough away from the screen as a result of space limitations, you may need to have a short throw projector. A brief throw projector will allow you to mount the projector considerably closer towards the screen, although still displaying a wide adequate image to fill the entire screen.

If for some reason you cannot spot the projector exactly perpendicular for the screen, keystone correction permits you to appropriate distortion by digitally adjusting the image so it really is completely square around the screen or wall.

Lens shift, around the other hand, permits you to mechanically adjust the angle on the lens by shifting it up, down or sideways. Since lens shift retains 100% in the resolution within the projected image, it’s a much better strategy to correct distortion than keystone correction.

Keystone correction is obtainable on nearly every single projector, providing a quick approach to adjust the image on data projectors and pico projectors, which get moved around most frequently. Lens shift is offered primarily on high-end home theater projectors, exactly where the projector will likely be installed semi-permanently on the wall or ceiling.

Final Thoughts

When it comes to screen size, many individuals feel that larger is automatically greater. But that is not often the case. Projecting too huge an image may possibly make a image with much less than optimum brightness, or noticeable pixel structure.

The size from the image also determines how far you must sit in the screen for optimum viewing. For an HD-capable projector, the basic rule of thumb for viewing distance is 1-1/2 instances the screen diagonal – so if your screen’s diagonal measurement is 96″ (eight feet), you’d wish to sit about 12 feet in the screen. For those who have a 4K Ultra HD projector it is possible to sit as close as 1 instances the screen diagonal. That is considerably closer than many people are employed to, but you really need to sit closer than inside the previous to be in a position to determine the added image detail and texture. Needless to say, viewing distance is extremely subjective. After all, inside a film theater, folks naturally spread out from the front row to the back, and everywhere in amongst.
