These days, having a reliable projector is becoming harder to select as many projectors are available in the market.
Also, the price of full HD 1080p models has decreased due to the easy availability of 4k models.
In this article, we bring you the EH412st, which delivers the true 1920×1080 picture quality and can be used for multiple working purposes.
So, with multiple features and full HD 1080p resolution, we bring you the full details on the Optoma EH412st review guide.

This model provides a resolution of Full HD of 1920 x 1080p and supports 4k content with the help of the HDR feature.
This device will provide clear images even in brighter conditions due to its high power lumens of 4000ANSI.
So, it can be used in classrooms, business meetings, churches, houses, etc. Also, it provides a deeper black-level scene due to a contrast ratio of 50,000:1.
The company also claims there will be no fading, and colors will be accurate on-screen due to its color wheel and 10-bit color processing feature.
If you are shorter in space than a classroom, bedroom, or business meeting place, this projector will project the image 100″ inches just 6 feet away.
Setup & Installation ProcessRight out of the box, I quickly placed the EH412ST on the table to test the image quality.
The projector was placed “five feet away” and got an image size of 120″ inches.
But you will have difficulty adjusting the image as the Optoma does not have an autofocus feature. So, every time the projector is moved, the focus will take a lot of time.
But if you mount the projector on the ceiling, it will take a lot of time to adjust the image with focus zoom to fine-tune image clarity.
The Optoma EH412ST is less than 7 pounds, so you will not have difficulty lifting the unit if you want to take it with you for office work.
I would say the audio quality was better than Optoma HD146x, which comes in the price range of $1000.
So it has 10-watt integrated speakers, which will give enough if you use it in the classroom, meetings, training classes, etc.
But if you have set up this device in your living room, I suggest you connect this model to an external speaker to get a cinematic experience.
ConnectivityYou will get multiple options for connecting different devices to run on the bigger screen.
There are VGA in and out, 2 x HDMI, audio-in and out, USB-A, and RS232 options.
- Lumen’s power of 4000 lets you use it in brighter conditions.
- It also supports 4k content with the help of HDR technology.
- Multiple connectivity options let you connect USB, HDMI, Audio ports, etc.
- Acceptable sound quality.
- Longer lamp life of 15,000 running in low power mode.
- No wifi or Bluetooth feature in a price tag of above $700.
- The keystone and zoom focus cannot be adjusted automatically.
- You cannot place the projector too close to the screen as the white light will be brighter in a darker room due to 4000 bulb power.
Can I Use Optoma EH412ST For Gaming Purposes?
Yes, you can use it as a casual but not a professional gamer. This is because of its higher lag time of more than 36ms.
Will This Model Get Heated When Running For a Longer period?
Yes, it will get heated when running for more than 3 hours at a high brightness level. But the internal fan system will cool down the heating.
But the fan noise will be much louder if you are using the internal audio system of Optoma, and you can hear it easily if you sit close to the projector.
The Optoma EH412ST is perfect for use in multiple locations where you don’t have control over the lighting system.
Also, the build quality is solid and can be placed anywhere you like to project the images on the screen.
So, if you are looking for decent speakers, clear image quality, and has short throw ratio where space is a problem, then Optoma EH412ST is an ideal choice for you.
