Which budget projector is best for classroom teaching? The less you spend, the more you’ll have to give up. Generally, the most affordable projectors have low native resolutions and aren’t bright enough to project large, watchable images.
What about those projectors that claim 1080p and 4K support at absurdly low prices? These are frequently deceptive, referring to input capability rather than the projected image. You’ll notice that cheaper machines are frequently limited to 480p and lower resolutions if you read the longer descriptions.
How bright do you need it to be?
Which budget projector is best for classroom teaching? The light source used by a projector is the most important factor in determining its brightness. Many low-cost projectors use an LED source, and the advantage of the low brightness level is that the light source lasts a long time, often up to 20,000 hours or more. Traditional lamps often provide higher brightness levels, but the bulb may only last 4,000 to 6,000 hours, requiring replacement after three or four years if used frequently. Remember that some low-cost projectors aren’t designed to be used for extended periods and may fail long before the lamp does, as heat and dust wear down the optical system and moving parts.
What kind of connectivity do you require?
It’s also important to consider how you intend to use your projector. Most will have an HDMI input for connecting a game console, Blu-ray player, or streaming stick. Many will even let you play video files from a USB thumb drive. Which budget projector is best for classroom teaching?
However, projectors with smart TV features and built-in apps like Netflix, Amazon Prime Video, and BBC iPlayer are also worth considering. Some also allow you to cast video or screen mirrors from a mobile device and send audio to headphones or Bluetooth speakers.

Is it better to have a portable or a mains-powered device?
Many projectors at lower price points are on the small side. Indeed, cheap frequently implies portable or even battery-powered. Avoid pocket-sized, battery-powered projectors in favor of a mains-powered machine if you want the sharpest, brightest image for your money. Which budget projector is best for classroom teaching?
A mains-powered projector is more likely to have a bright lamp to produce large, bright images, and it is the best choice for watching movies in your bedroom or living room if you don’t need to move it around too much. Which budget projector is best for classroom teaching?
What other characteristics should I look for?
Autofocus and auto keystone: Save time in image setup by eliminating the need to fiddle with menu settings and focus wheels.s
Control via remote: Most come with one, but some don’t, and it’s a real pain if you don’t. Audio output and speakers: Many models have built-in speakers, but most aren’t very good, so check for a 3.5mm audio output or Bluetooth capability to connect an external speaker.
Bluetooth: This isn’t used to transfer video because the technology needs more bandwidth, but some products use it, so the projector can also function as a Bluetooth speaker.
Throw-to-catch ratio: It may sound technical, but it refers to the image size that the projector can create from a given distance. Short-throw projectors can project large images from close to a screen or wall. A throw ratio of 1.5 means that for every 1.5m the projector is away from your wall, an image width of 1m is created, a 3m distance produces an image width of 2m, and so on.
