What are the Differences Between Wimius K3 vs P28 Projector

What are the Differences Between Wimius K3 vs P28 Projector

Image Quality

Both the Wimius K3 vs P28 are DLP projectors, meaning they use a digital micromirror device to bounce light onto the screen. This is different than older LCD (liquid crystal display) projectors, which used a backlight for illumination. Each pixel on the micro-mirror is one of the thousands that can be switched on or off to create color.

These “on” and “off” pixels create the color red, green, and blue (each pixel is a combination of all three colors). The light beams are created by a separate instrument that regulates their intensity and repetition at high rates to generate pictures.

Both projectors’ native resolution is 1920 x 1080. However, the P28 has both a 16: 9 Aspect Ratio option for 1080p input signals and a 4:3 option for 480i/p input signals.

Both projectors have great brightness – 9500 ANSI lumens on the K3 vs 2000 ANSI lumens on the P28. Wimius projectors lack keystone correction. However, they can be hung upside down or sideways without impacting image quality.

Both projectors use the same LED light source with an estimated lamp life of 20,000 hours in ECO mode and up to 10,000 hours in Bright mode.


Design-wise, the Wimius K3 vs P28 projectors are different. The P28 is a cube design with its inputs and other ports on the back of the projector. You have to lay it flat or face it upwards to use these ports. The K3 has all its input ports on the side, making it easier to access, and lets you stand it up or lay it flat.

Both projectors lack a lens shift – meaning they cannot adjust the projected image up or down after being positioned. The K3 does have a 100-75% manual zoom, which is fairly standard for a business projector. In contrast, the P28 has 100% to 75% manual zoom, which is great for larger rooms. The K3 weighs ‎8.05 lbs, while the P28 weighs 5.5 lbs.


Both projectors have HDMI inputs – two on the K3 and one on the P28. They also both have VGA inputs, although the P28 has a DVI input. The K3 has an audio-in port, while the P28 does not.

Screen Size

Wimius P28 vs K3 projectors can produce a 100″ image. However, the P28 has an advantage if you plan to use it with larger screens. Its lens has a 1.5x optical zoom, which allows you to place the projector away from the screen and closer to where you’ll be seated without sacrificing image quality or size. The K3 has a 1.2x optical zoom, which is fairly standard for most projectors in this price range.

Sound Quality

Both projectors have built-in speakers. The P28 has a single 10 W speaker, while the K3 has two 5W speakers. In testing both projectors’ built-in speakers, we found that sound quality was very similar across both models – they got fairly loud but were somewhat tinny and lacked bass. Of course, most people will want to use external speakers when they are available.

5G Wifi Functionality

Both the Wimius P28 vs K3 have 5G wifi capability, which means you can connect to them quickly when in range. You’ll need the free Wimius Mobile App, which you may get from your app store.

We recommend trying both projectors with this feature – it’s an excellent convenience that really makes using these projectors in an office or boardroom easier. For both projectors, this feature offers the following functions:

  • Remote Airplay
  • Email Notification
  • Auto Power Off Timer
  • Network Connection Test

The K3 also offers these additional features via the Wimius Mobile App:

Screenshare: This lets you mirror your mobile device’s screen to the projector. Allow us to share it with you! This is perfect for showing from your phone or tablet!

Online Conference: Which lets you use the K3 as a video conferencing display when connected to wifi, then project what’s on your laptop via USB cable.

Warranty & Support
