Before coronavirus hit the world, we used to go out and watch movies on a big screen while munching on movie theater popcorn. It doesn't hurt that it also delivers 1080p native resolution, was bright enough in our tests to fill a 90-inch screen in low levels of ambient light, and even comes with an Android TV dongle. There’s likely quite a few people that forget about this step and it has to be done every time you move the projector to a new location. Otherwise, you might need an adapter or get a compatible projector to make it work, especially if it’s a vintage device linked to a modern projector or vice-versa.

Check the connection, the power cable, the electrical socket, and so forth for bent pins, warped plastic, a large hood, or looseness.But it's big enough to have an HDMI port, which means it can connect to most video sources, including mobile devices (for screen mirroring). If your projector is able to display the menu then it might be a video source issue or cable/port connection problem. Even better if your projector is still under warranty because that means you can get the lamp for free. Some models, most often portables, offer USB-C ports, which can (but don't always) support DisplayPort and HDMI protocols. Most of my current work for PCMag is about printers and projectors, but I've covered a wide variety of other subjects—in more than 4,000 pieces, over more than 40 years—including both computer-related areas and others ranging from ape language experiments, to politics, to cosmology, to space colonies.

Ultra short throw (UST) projectors can throw large images from close to the screen, avoiding the need to run cables through walls and ceilings. But you can use a TV stick or Roku stick to watch content from Netflix, Hulu, and similar streaming services.

On the top of the machine is a physical focus wheel and a keystone wheel that you must adjust manually to sharpen your image after setting up your projector. This can lead to rainbow artifacts, in which bright areas on the screen break up into little red-green-blue flashes for some people when they shift their gaze or when something moves onscreen. Some take advantage of the width to add what amounts to a sound bar on the side facing away from the screen. Business users and educators who need a bright image above all else and have no need to show images with small fonts or fine detail should consider the EX7280 a strong candidate, particularly if they need to move the unit from place to place.
