Some video projectors include audio inputs and onboard speakers, but like speakers built into TVs, they are not great. It is best to connect your audio source to an external audio system (even a modest one) for a better viewing experience.
Variants of LCD technology include LCOS (Liquid Crystal on Silicon), JVC's D-ILA (Digital Imaging Light Amplification), and Sony's SXRD (Silicon Crystal Reflective Display). With LCOS/D-ILA and SXRD projectors, the light source reflects off the 3 LCD chips instead of passing through them.
Yes, providing you buy the right projector for the job. For example, a regular projector won't be good enough for gaming. A good gaming projector must offer a high resolution, fast refresh rate, and low input latency.
It depends. When deciding between a video projector or a TV, consider your specific needs for the device. TVs are best for everyday use. Projectors are best for special occasions and niche applications.
Besides these ratios, other factors should also be considered: how much ambient light is available where you place your projector? And what will you be projecting it on? Not just contrast ratio should be taken into consideration.
Are you looking to put your projector indoors or outdoors? Not just any projector will do; you also need to take the environment and its ambient light into consideration. Will it only be watched by a few people or many viewers? What size is the room the unit is placed in?
If you are looking for a projector to enjoy the best movie-watching experience, then instead of buying a commercial projector, go for a home theatre projector. The home theatre projector delivers the user with incredible image quality with rich saturation, high contrast and deep blacks. These projectors work best in a room where the amount of light entering can be controlled. Choose a projector with 4K resolution, offering you HDR compatibility and high contrast ratio. With high contrast ratio, you can experience a sharper picture quality be it numbers, pictures, text, graphs, or video.
For OfficeCommercial projectors or projectors for offices are primarily for displaying static images, like graphs and PowerPoint slides, but they can also work great for multimedia and entertainment use. For office projectors, the main thing to keep in mind is the lumen output. For office purposes, you can either choose a short-throw projector or a regular projector.
Having projectors in classrooms can make the whole learning process lot of engaging and super fun. Classroom projectors have the same features as the commercial projector but utilize low resolution. Buy projectors that have built-in speakers as it makes the whole presentation process in a school easy.
Display Resolution is a very important aspect. Both DLP and LCD projectors come with a fixed number of pixels. If most of the thing you will view from a projector is HD, then try to buy a projector with high pixels. A pixel count of 1024×768 is sufficient for DVD. 720p HDTV signals require a 1280×720 pixel count for the display, while a 1080i HDTV input signal needs a pixel count of 1920×1080.
Contrast ratio and brightness go hand in hand. Contrast basically refers to the ratio between the black and white portions of an image. High contrast ratio delivers whiter whites and blacker blacks. Even if you have a projector with an amazing lumens rating, but the contrast ratio is low, your image will look completely washed out. A contrast ratio of at least 1500:1 is good, but 2,000:1 or higher would be an excellent option.
Color reproduction is one more important factor to be considered. How colors appear in the darkest and brightest area of the image is also important to get the best output from your projector. Check out the color depth and natural tones of the projector.
Always ensure that your projector has all the inputs that you need. The most common inputs in a projector are HDMI, VGA and DVI. When shopping for a projector, it is very important for one to make sure that it has all the input connections you need.
Portability is very important not just for moving and travelling purposes but also while installing and setting up. If the projector is portable, you can watch anything anywhere you like, even on a plain white bedsheet.
Well friends, buckle up and turn down the lights, you've come to the right place. We're going to answer those questions and a few you might not have known to ask. But if you want to skip all that and just get our recommendations, check out the best projector for home theater in 2020.
One of the most important specifications for projectors is "lumens," which describes how much light a projector can create. This, in turn, determines how bright the image is and how big you can make it. There are a lot of problems with this spec. For one, other than the distinct "ANSI lumens" there's no agreed-upon way to measure lumens. One company's 3,000 might be another's 3,500. Most manufacturers don't specify ANSI lumens, which would be easier to compare across brands.
You can compare broad strokes however. Generally speaking a 3,000-lumen projector is probably brighter than a 2,000 model. But if you're trying to choose between 3,000 and 3,100 lumens, good luck. Even if those numbers were accurate, that little of a difference probably won't be visible anyway.
So how many lumens do you need? Well there are some considerations we'll get to, but generally speaking you probably won't regret getting the brightest projector you can. Other aspects, like color accuracy, contrast ratio, and more, are vital, but for an initial sweep of potentially promising projectors, see what kind of lumen output is available in your price range. It's worth keeping in mind that you can usually turn down the brightness of a projector, but you can't turn up an otherwise dim projector. That is, unless you make the image smaller.
To give you a rough idea, a 2,000-lumen projector will create a bright, watchable image on a 100-inch screen in a dark room. A 1,000-lumen projector will be "fine" but won't really punch. 3,000 and over will be very bright, perhaps too much so for some viewers. These are all very rough numbers which, again, are hard to compare since the specs themselves are suspect. If you look at our reviews, and what results we've gotten with measurement gear, it might give you a better idea what you're looking at.
Projectors create light and image separately. A light source creates the light, which is then focused on an image-creating chip. Modern projectors use one of three technologies as light sources: LEDs, lasers and UHP (ultra high pressure) lamps.
UHP lamps, which are basically high-powered light bulbs, are by far the most common. These are capable of creating a lot of light and have the added bonus of being fairly inexpensive. The downside is they degrade over time. A UHP projector will never be as bright as that first time you turn it on -- until you replace the lamp.
This aging is a slow process though. We've reviewed several that, in certain modes, have lamps that can last 15,000 hours before you need to replace them. So if you watch the projector for four hours every night, that means the lamp will last over 10 years. Prices vary, but typically a new lamp will run you $100-$300. More expensive projectors have more expensive lamps. Go figure.
Relatively new to the home theater projection scene are LED and laser light sources. These are cooler than UHP lamps in both senses of the word. LEDs and lasers in projectors function in similar ways and some projectors use both, so for our purposes we'll group them together. They're far more efficient than UHP lamps but cost a lot more to create the same amount of light. If you had a $1,000 lamp-based projector and a $1,000 LED or laser projector, the UHP-lamp projector is going to be brighter. There are lots of affordable LED-based projectors available today but they're usually quite dim. That probably won't be the case forever, but it is right now.
I absolutely understand the appeal of LED/laser, especially since they're often rated for 30,000 hours. Not having to replace the lamp, aka spend money on something you've already spent money on, is completely understandable. However, the price/performance ratio of UHP lamp projectors still can't be beat. Having to spend ~$150 every 5 to 10 years doesn't seem outrageous. You also have a much wider range of UHP projectors available, from many different companies.
After the UHP lamp/LED/laser creates the light, some kind of chip manipulates that light into an actual image. There are three technology types when it comes to projector chips: DLP, LCD and LCoS. We go into these technologies into greater detail in DLP vs LCD vs LCoS: Projector tech pros and cons, but here's a short list of the highlights:
The image chips are one of the most confusing, but also most interesting, aspects of projectors. Despite dozens of companies making projectors, the chips are almost all made by just four companies. Every DLP-based projector uses a "light engine" made by Texas Instruments. This includes the chip and the color wheel (to make all the colors you see). How it's implemented in a case, the overall airflow, what lamp is used, how the settings are tweaked and more, are often done by the projector maker, aka the name on the outside. Some companies just use a reference design and slap their name on it. Others might use the base reference design, and then tweak it to their specs. That all said, two DLP-projectors that cost the same, but are from two different companies, are going to look more similar than different. Probably not identical, though. There's still a lot that can be tweaked.
For LCD, Epson is by far the biggest name. Lower-end models typically have very poor contrast ratios. It's just harder to get a good black level with LCD, something that's true with TVs as well. However, Epson has come a long way in recent years. Its Home Cinema 2150, for instance, had a better contrast ratio than many competing DLP projectors. They're all three-chip designs, as in there's a separate chip for the red, green and blue components of an image, so it's possible for them to have better color compared to many DLP projectors, which usually rely on a spinning color wheel. This largely varies per projector, however. 781b155fdc
