ViewSonic PX747-4K - best cheap 4K projector

ViewSonic PX747-4K

It’s a cheap 4K projector with 3840 x 2160 resolution. It features 3,500 lumens and can be used in a partially darkened room. Note that it’s not a full HD projector that’s why it doesn’t support a 3D projection.

It’s a DLP device and it means that the processor’s chip is based on the pixel-shifting tech to reach a true 4K resolution that demands M8.3 distinct pixels. The PX747-4K also has an RGBW color wheel that is designed for both home entertainment and education/business presentations. Since it enhances the numerous lumens the projector outputs, it lets a lot of light pass through and, after all, provides an extremely bright image. Besides, black level performance is great for such a budget unit and allows seeing details in dark scenes.

This model is also remarkable for its long lamp’s life that reaches 15,000 hours when the SuperEco is switched on and 50ms input lag that makes the projector suitable for gaming.

This projector has two HDMI inputs (both of them support 4K content) and that’s not much. So, it’s not possible to connect, for example, PS4, a 4K UHD player, a TV simultaneously. The device comes with mini-USB port for mobile devices.


  • No definition to a pixel when sitting close to a projector. It is all tiny and smooth.
  • Can be connected to a Chromecast Ultra to provide effective 4K and HDR streaming.
  • The unit is compact and weighs just 10 pounds. It can stay on a table or be mounted inverted on the ceiling.


  • It does not support the expanded color space P3/BT.2020 but just regular HDTV.
  • No cover to protect the lens from dust.

The unit provides accurate and well-focused picture across the surface of the screen and the sharpness isn’t fading on the edges. Besides, it requires just 10 feet to fill a 120-inch diagonal screen while the majority of other units need 13 feet and more.

The projector comes with typical 2,400 lumens that mean the irrationality of using Bright mode for any video display in order to avoid getting a green picture. The unit allows calibrating brightness on a scale on 0 to 10. The colors are rather saturated even when the brightness is at max. The device is able to upscale HD 1080p material up to 4K and produce good sharpening and clear picture.

Color balance and video are great by default that allows dispensing long-time calibration. However, to make a picture even more neutral, one can make small adjustments to achieve red and blue’s balance.


  • Setup is straightforward and the menus are readable and easy to understand.
  • Both HDMI ports are HDMI 2.2.
  • HDR auto mode works flawlessly and it recognizes HDR in a matter of seconds.

It has high (30,000:1) contrast ratio to provide an extremely dynamic image. Blacks are deep enough but, certainly, they’re below OLED TV’s blacks. That’s not the projector’s issue but the specs of the tech. No budget projector has as deep blacks as high-end models. This gadget is designed with a great contrast between whites and blacks.

The projector has speakers on board, but, like any other affordable model, it needs extra speakers to make sound deep and loud enough. This model handles 3D content and performance. When connecting and turning 3D Blu-ray on, the projector locks on automatically and switches to 3D mode.


  • No off-putting buzzing at start, it works with minimum noise that is barely audible.
  • 4K image is sharp.
  • High picture clarity with very a few adjustments.

How to Choose Budget 4K Projector for Superior Picture?

When thinking of a low-cost 4K model, one should understand that all those projectors aren’t true 4K units. They just use shifting to reach this effect and compensate for the lack of pixels up to the necessary M8 PX. So, a projector that’s able to produce pictures with the 4k resolution is a 4k device.

Since there’s no choice in terms of technology, one should pay attention to some other budget models’ features.

Lamp life is crucial because the majority of models have no extra lamps in the box. It’s necessary to consider the range between common service life and the lamp’s lifespan in the Eco mode. 15,000 hours at max is a decent parameter towards the cheap 4K projectors.

Not all low priced units feature 3D display. It’s not an issue if not watching 3D content. However, those who want to enjoy this format should check the model’s ability to support 3D.

Brightness is crucial to watch video comfortably at all hours in both illuminated and darkened rooms. Despite that fact that all projectors are designed to perform in the darkness, high-quality models are able to produce a good picture in the natural/artificial or ambient/direct light. The more lumens a model has the higher brightness it ensures.

Though 3,000 lumens are quite enough but also a good contrast ratio (no less than 12000:1), high image sharpness and video smoothness should follow them to provide perfect brightness.

Before purchasing a projector, one should consider a screen’s dimensions because most of the budget units are developed for 120-inch displays. In case of having larger screens, the larger rooms are required to install a projector at the right distance.

If having a small room, bear in mind the projector’s throw ratio that is in the range of 3–15 feet. Choose the short throw projectors to get an accurate picture.

Sound is not a key feature, but it’s possible to find out a model with the built-in speakers. However, they’re not powerful at all that’s why one still needs additional speakers to get a good sound.

HDMI ports are necessary to watch 4K content. However, VGA, USB type-A and type-B, RS-232 ports are desired to get enhanced connectivity and use a wide range of devices.
