Home » COMPARISONS » LG HU85LA VS Optoma Cinemax P2

Most home theater projectors produce stunning HD images whether you’re streaming content or watching a disc. Chances are you don’t have any complaints about image quality, but you can do better. 4K UHD projectors give you stunningly bright, crisp, and clear images and most are as simple to set up as the full HD models.

Two projectors that are worth taking a look at are the LG HU85LA and the Optoma Cinemax P2. Both are short-throw 4K UHD projectors, but the Optoma Cinemax P2 produces a slightly brighter and more vivid picture. Both models are a breeze to install, though the P2 from Optoma is a few pounds lighter. The Optoma P2 also comes with plenty of extra features (>>> Check current price on Amazon).

These two home theater projectors are similar, which is why it always helps to take a closer look at and compare each model’s specifications.

Each of these projectors comes with several of the same specifications and features, and comparing the two will make it easier for you to know which is the right one for your home entertainment setup.

Image Quality

You’ll get amazing image quality with either home projector. Both boast true 4K UHD resolution and come with HDR10 support. 10-bit color processing technology ensures accurate colors and a dynamic contrast ratio produces crisp whites and rich, inky blacks.

The picture is slightly brighter with the Optoma Cinemax P2. It comes with a 3,000 lumens rating, compared to the 2,700 lumens you get with the HU85LA. You’ll also notice colors are more vivid on the P2, due to the 6-segmented color wheel that also helps prevent colors from appearing faded.

Ease of Installation and Use

Installing and aligning images is a breeze with both models, though the Optoma P2 is a couple of pounds lighter. You won’t want to move either projector around, they both weigh over 20 lbs., but you might find it a little easier to get the P2 projector out of the box. It also comes with an Android OS for easy operation.

You only need a little over a foot of space between the projectors and screens to throw 100” images. Digital keystone correction that includes horizontal and vertical alignment, along with automatic zoom makes aligning on-screen images quick and easy. If you’re having problems getting images to the center, you can use the convenient geometric correction function.

Included Features

There are plenty of included features with the two home theater projectors, but the Optoma P2 comes out ahead. Both come with Amazon Alexa, Google Assistant, and streaming apps while the P2 includes IFTTT support.

One function that the HU85LA has that’s missing from the Optoma P2 is Miracast support. It allows you to mirror connect from one device and watch it on the projector. With all of the other features the P2 projector comes with, the lack of Miracast is not a deal-breaker.
