Think back to the last time you made a big purchase. Whether it was a new car or a new smartphone, hopefully you did some research first. A projector is no different. It’s something that you’re going to spend a decent amount of money on and it’s going to last you a long time. You want to make sure that the projector you buy is going to have all the features that you need, without overpaying for extras that might not be necessary for you. In this post we’re going to break down the projector specs that you need to understand when you’re shopping for a new projector. 


DLP and LCD are two different types of microdisplay imaging technologies. DLP stands for Digital Light Processing while LCD stands for Liquid Crystal Display. Both types of projectors have their own advantages and disadvantages. One of the main factors to consider when deciding between these two is whether you need your projector to be portable or not. LCD projectors are typically less portable than DLP, but they do tend to have better overall image quality, which makes them a great choice for home theaters or living room uses. One highly recommended DLP projector is the BenQ HT2050A, which uses a 5J.JEE05.001 replacement projector lamp. If you decide on an LCD projector, something like the Epson Home Cinema 5050UB is an excellent option which uses the very popular V13H010L89 replacement lamp.

Lumens are essentially a measure of the brightness that your projector will be able to display. The amount of lumens that you need will be different depending on what you plan to use your projector for, and where you plan to use it. For example, if you plan to use your projector in a room where there is not too much ambient light (like a home theater), you won’t need an overabundance of lumens. On the other hand, if you are using it in a living room or classroom where there are generally a lot of windows and light, you will need a projector with a fairly high lumen count. A great example is the Viewsonic VS16369 projector, which has a lumen count of 5,200, and uses a RLC-103 replacement lamp.

Long Throw, Short Throw and Ultra Short Throw (UST)

Throw Distance of a projector

The ‘throw ratio’ of your projector is a measure of how far away the projector can be from the screen. Long throw projectors, like the BenQ TK800 (which uses the 5J.JHN05.001 projector lamp), can be placed much further away than short throw and UST, which is great for areas where your power source is not close to the screen. Another thing to be aware of when using long throw projectors is that if there will be a lot of people walking in front of it, you’ll be seeing a lot of shadows. You won’t have to worry about that with a short throw projector since it can be placed so much closer to the screen, which is one of their main advantages. Then there’s ultra short throw projectors which utilize the latest advancements to throw technology. They can still display the same size images from an even closer distance, which is ideal for an area with very limited space. 

Contrast Ratio

The contrast ratio is also very important when it comes to buying your projector because it will affect the image quality quite a bit. It’s defined as the ratio between the black and white aspects of the image. In a dark room, the contrast ratio will not be as noticeable, but in a bright setting, a low contrast ratio will cause images to look washed out. A projector with a high contrast ratio will deliver the blackest blacks and the whitest whites, like the Optoma EH200ST, which has a whopping contrast ratio of 20,000:1.
