The Epson and Optoma actually looked relatively close, although the Epson was noticeably brighter, at least when the Optoma is in one of its more accurate modes; colors looked a bit richer on the Epson as well. 

With the Optoma HD146X in Vivid mode, the eye gets drawn its brighter highlights, even though the contrast ratio isn’t much different. The colors and color temperature are less accurate than the Epson 2150, especially in this mode, but I could imagine many people being far more interested in the greater brightness over accurate color.


Optoma HD146X

The projector only displays 1080p signals and has much better brightness and dynamic range. The blacks are pretty good and the brightness is good even in rooms with ambient light.

Epson 2150

The 2150 can accept signals up to 1080p/60, no HDR or 4K, which is fine as this isn’t an HDR or 4K projector. 3D TVs are dead but projectors like the 2150 still show 3D movies, although glasses aren’t included. The $99 glasses are out of stock on Epson’s site, but there are third-party alternatives on Amazon.

The rated 3,500 lumens is bright enough to project onto a 1.0-gain white screen for a 270-inch-diagonal 16:9 image in a dark room. In ambient light, the suitable size is 150 inches in Bright mode, and smaller still for the modes with better color accuracy.

Epson 2150

Epson 2150 claims a maximum light output of 2,500 lumens. With my sample, I measured an impressive 1,620 lumens (it’s normal for projectors to measure less than their claimed specs). This is far less than the brightness of most TVs today, but bright compared with projectors and TVs from a few years ago. On a 100-inch+ screen, it’s a lot. The claimed contrast ratio of 65,000:1 is the only spec that’s higher than the wired version of this projector, the slightly cheaper HC2100..


All small projectors have loud fans, that’s just the tradeoff for a bright image from a small product. That said, the ones in the HD146X are a bit more noticeable. For instance, it’s not appreciably louder than the Epson, but the tone of Epson’s projector noise is more easily ignored than the Optoma’s.

Lamp life

Optoma HD146X

Doing so bumps the claimed lamp life to an even more impressive 15,000 hours but also causes the fan to ramp up and down, which makes it even more annoying. This is true of most “Dynamic Black” type features, but is especially noticeable on the HD146X.

Epson 2150

Lamp life is a claimed 4,500 hours, or 7,500 in the much quieter, but dimmer, Eco mode. This is good for this price range. To put this in perspective, if you were to use this projector as your main “TV,” watching it 4 hours every day, the lamp in Eco mode would last you over five years. For comparison, the BenQ’s lamp life, in its Eco mode, is 5,000 hours.


Both Optoma HD146X and Epson 2150 also have wireless connectivity. Using Miracast, you can send content from your laptop to the screen with minimal setup fuss, but it’s not ideal. Miracast can be finicky, and this setup will rely on you having your laptop (PC only, mind you) open and playing the content. If you don’t want to run an HDMI cable, streaming sticks are cheap and will be easier to use in the long run because you’re just sticking them into the projector itself. Roku also has Miracast built in so you could still stream content from your computer to it.

Optoma HD146X vs Epson 2150 Customer reviews

Great Projector for this price point.

Purchased this projector to have movie nights outdoors with the family via my Roku. Picture quality is great and very bright. I hooked up a Bluetooth adapter to the Aux port and have two speakers with stands that I connect with Bluetooth. Very happy to the quality. Watched Avatar the first night and picture was crisp and colors were vibrant. This projector exceeded my expectations. Would have been nice to have built-in Bluetooth and an extra HDMI port, but overall this is a great projector for this price.

I love this projector!

I have recently become very interested in projectors. I bought a small anker Portable projector a couple years ago that kinda kick started my interest. I finally started doing some research about projectors and have learned that the technology in Epson’s line of projectors called “3LCD” chips do not project a rainbow effect like traditional DLP projectors can.

Anyway lol all that being said, the epson 2150 home cinema projector is pretty amazing! It is bright enough to use with some window or ambient lightning even in eco mode. Colors are very vibrant and even blacks are as dark as they should be. The fan is also hardly noticeable when in eco mode. If you set it to bright the fan will kick up speed and you’ll hear it if you’re sitting near the projector but even then it isn’t very bothersome. Especially if you have nice speakers connected to the projector. It has two HDMI ports, VGA and audio out.

The built in speaker doesn’t sound very good but it is fine if you’re in a pinch. You’re going to want to connect a good speaker for home entertainment anyway. I was on the fence for about two weeks between this projector and two other brands of DLP projectors great claimed to be “gaming” projectors and I am very glad I decided to go with the epson projector. I binged movies and tv for 7 hours the first night I set it up 😀 .

I also tested it with the Nintendo switch and gaming on it was fine. Epson states that it has a 29.2 ms “input lag” and it honestly felt responsive. I played Mario Kart with no issues. It might not be good for hardcore gamers but I would compare it to playing on a tv with game mode turned on. I think it will be just fine for shooters and fighting games too. The pictures I am sharing are about a 90/100” picture on a plain white wall. I don’t have a screen set up yet and as you can see, picture quality is still very good! I highly recommend this projector if you are looking for a very good “affordable” projector.

Pros : Bright and vivid picture quality Great contrast Vertical and horizontal keystone adjustment Vertical Lens shift Good for gaming 4500-7500 hour projected lamp life No rainbow effect WiFi , Bluetooth and miracast

Cons : built in speaker isn’t very good
