4K quality is just a plugin away with TOTU's 4K pass through device. The device connects up to 4 HDMI source components to one HD display. The four HDMI sources can be anything from a gaming system to a Roku. We found that the sky is the limit with what you can plug in––you can connect anything with high-quality technology like 4K, or older technology. Both will work just fine!
The switch supports up to 4K and 60Hz and a channel bandwidth of 18 Gbps. It works with older HDMI sources too.
After plugging in your various devices, you'll want to take advantage of the super simple remote that has a button for each of the four inputs. Then, you can easily navigate from input to input, enjoying 4K quality over four channels.
The result is gorgeous quality 4K from various sources, all plugged into the same small device.

What really sets Zettaguard apart from the rest is the unique remote equipped with picture-in-picture (PIP). PIP is kind of a big deal in the TV world––this feature can maintain up to three sub screens on one main screen. This means you can juggle several inputs being in use at the same time in the same place. Pretty cool, eh?
This allows you to multitask and switch between main displays seamlessly with the remote. We liked the option to multitask––it especially comes in handy if you're juggling a movie trailer, YouTube video, video game, and movie all at once!
In addition to PIP technology, Zettaguard's 4K pass through supports formats up to 4K2K at 60Hz and is compatible with most Blu-Ray players, DVD players, satellite boxes, and more. It even works with 3D technology.
- PIP remote features allows three sub screens and one main screen display

We're a fan of SGEYR's HDMI switch/pass through because it goes above and beyond with input opportunities. Four slots seem to be the standard for pass throughs, which is why we love that SGEYR's didn't stop with four and did five instead!
The switch can support high definition resolution like 4K at 30Hz and full 3D, including smaller resolutions, too.
Another feature we like is the LED lights that indicate which inputs are in use, so you always know. The remote is super straightforward to use, but keep in mind, AAA batteries will be needed.

- Straightforward and easy-to-navigate remote
- LED lights indicate which inputs are up and running
KOOPMAN's pass through is an excellent option. Its four ports are compatible with HDR10 HDCP and older formats, 36bit per channel deep color, and the switch supports 4K at 60Hz and lower resolution with no problem.
What we really love about this one is the smart remote. If one input doesn't have a viable signal input, it'll skip to one with a solid signal automatically. The remote will also move immediately to the most recently inserted HDMI source. But don't worry, you still have plenty of control over the remote and can move from port to port with the remote.
Another perk of this pass through is that there's no delay or lag with your content passing through the device. It's speedy, efficient, and its plug-and-play design ensures you won't spend an eternity setting it up and trying to get your devices up and running.
- Smart features like auto-switch control on remote
- You can swap HDMI channels up to 15 feet from the box

Below we break down a few technical terms that might seem confusing to understand at first glance.
Resolution defines the quality of what's happening on your screen. The number stands for the number of columns and pixels on screen. As a rule of thumb, the higher the number of pixels, the crisper the image will be.
That's why 4K is all the rage right now––it offers the highest resolution available.
Hz refers to refresh cycles per second. This has a direct relationship with resolution of content. The number of Hz symbolizes how often the screen re-samples information, smoothing motion.
Picture-In-Picture (PIP) Technology
Picture-in-picture technology allows you to have several screens open at the same time on your television.
Ultra-High Definition (UHD)
As it sounds, UHD is super high-quality imagery, usually associated with the likes of 4K technology. You'll probably see them together in the same description because they both yield high quality viewing we can't help but fawn over.
High Dynamic Range (HDR)
High dynamic range changes image quality just like 4K and UHD do. Unlike those, HDR focuses on colors, contrast, and clarity.
