Don’t Buy A Projector Before Knowing This

If you’re in the market for a projector you’re probably excited about creating a fantastic home theater experience. But before you make that purchase there are several crucial factors you need to consider. Projectors come with a variety of features and specifications, and understanding these can be the difference between a disappointing buy and an excellent investment. This guide aims to equip you with the essential knowledge to make an informed decision. By the end of this article, you’ll have a clearer understanding of what to look for and why each aspect is important.


When it comes to projectors brightness is measured in something called lumens. This measurement indicates how much light the projector emits. Simply put, the higher the lumens, the brighter the projector. It’s particularly important to look for “ANSI” lumens, as this is an official and standardized rating that ensures you get a reliable measurement of brightness.

If you plan to use your projector in a room with a bit of ambient light or even at dusk/night outdoors, you’ll need a model with enough brightness to cut through that extra light. A projector with at least 2000 ANSI lumens will typically handle these conditions decently well, ensuring your picture is vibrant and clear, no matter the setting.


Modern projectors offer a range of connectivity options and it’s important to know which ones you’ll need. While HDMI is standard for high-definition video and audio, there are other ports like USB, VGA, and even wireless options that can be crucial depending on your setup. USB ports can be useful for playing media directly from flash drives, while wireless connectivity allows for streaming from smartphones or laptops without the hassle of cables. Assess your needs and make sure the projector you choose has the right connections for your devices. You may want to get a projector model with at least 2 HDMI ports so you won’t have to swap devices as frequently.

Color Quality

The contrast ratio of a projector determines the difference between the darkest black and the brightest white it can produce. A higher contrast ratio means more detail and depth in the image which will make your viewing experience more immersive. For example, a projector with a contrast ratio of 10,000:1 will provide a more dynamic picture than one with a 1,000:1 ratio, especially in scenes with significant shadow detail.

Input Lag

If you’re a gamer “input lag” is a critical factor to consider. Input lag is the delay between pressing a button on your controller and seeing the action on the screen. For gaming you’ll want a projector with the lowest possible input lag to ensure a responsive and smooth gaming experience. Look for projectors specifically marketed as “gaming projectors” or those that list low input lag in their specifications. If you don’t plan on using your projector for any gaming then you can ignore this.


For those who need a projector that can be easily transported, portability is key. Portable projectors are typically lighter and may come with built-in batteries, allowing you to use them without needing a power outlet. These are ideal for movie nights under the stars or on a camping trip. Check the battery life and weight of portable models to ensure they meet your needs. Also note that these models will very likely be LED-based projectors, so you may need to use them when there’s minimal ambient light.

Lamp Type

Projectors use different types of lamps and each have their own advantages and disadvantages. LED lamps tend to last the longest and are energy-efficient but might not be as bright as traditional bulbs. Traditional lamps, while usually brighter, have shorter lifespans and need to be replaced more frequently. Laser projectors offer a good balance, providing high brightness and long lamp life, but they can be more expensive. Consider how often you’ll use your projector and in what lighting conditions to determine which lamp type is best for you.

Picture Clarity

Resolution is another vital factor as it determines the clarity of the image. Common resolutions include 720p, 1080p, and 4K. For a crisp and detailed picture, especially on larger screens, a higher resolution is preferable. If you’re planning to use your projector for watching movies or playing games, opting for at least 1080p will provide a satisfying viewing experience.


While some projectors come with built-in speakers, the sound quality is often not as robust as an external sound system. If audio quality is important to you consider a projector with audio output options so you can connect it to a soundbar or home theater system. This will enhance your overall viewing experience making it more immersive.

Aspect Ratio

Aspect ratio refers to the shape of the projected image. The most common aspect ratios are 4:3 and 16:9. If you’re mostly watching modern movies and TV shows, a 16:9 ratio is ideal, as it matches the widescreen format of most current media. For older content or having presentations, a 4:3 aspect ratio might be more suitable. Some projectors offer multiple aspect ratio settings, allowing you to switch based on your content.


Choosing the right projector involves more than just picking the brightest one or the one with the highest resolution. By understanding factors like lumens, connectivity options, contrast ratio, input lag, portability, lamp type, resolution, sound, and aspect ratio, you can make a well-informed decision that meets your specific needs. Remember that a projector is not just a device; it’s an investment in your entertainment or professional life. Armed with this knowledge you’re hopefully now ready to find the perfect projector for your requirements.
