Why use multiple monitors?

display windows 11 second monitor flickering

Multiple monitors are used for one simple reason: additional screen space. More space allows you to run multiple programs at once without switching between windows or making endless mouse clicks.

If you need to engage with an application, you can effortlessly move your mouse between the displays, or simply leave them open for reference–tremendous assistance when writing an essay or an article. You might even watch a movie or a TV show while working on the main screen from time to time.

Assume you’re the company’s social media manager. You can monitor what’s going on on Twitter with Tweetdeck open on one display.

Meanwhile, on your primary screen, you can be working on a report with a web browser open to your company’s analytics dashboard on one side and Microsoft Word open on the other.

If you’re a writer, you may use half of one monitor for a text editor, the other half for notes, and the secondary monitor for research.

Having all of these programs open at the same time demands that your PC has sufficient processing capacity, but most mid-range PCs with a Core i5 CPU or higher should suffice.

However, if you want to run a video editing tool like Photoshop alongside some other apps, you’ll need a lot of RAM to avoid the system stalling.

Multiple displays aren’t the only option. For example, you could buy a massive 4K panel and then utilize Windows Snap to divide your screen into quarters, thus generating four smaller 1080p places.

However, as compared to using numerous monitors with greater window widths, this can be a little uncomfortable.

Is there an HDMI splitter for dual monitors? 

An HDMI splitter splits a device’s HDMI video output, such as a Roku for instance, into two distinct audio and video streams. After that, you can send each video feed to a different display.

Unfortunately, the majority of splitters are terrible. Due to a built-in anti-piracy feature called High-Bandwidth Digital Content Protection, many don’t work (HDCP).

HDCP is an anti-piracy feature that can be found in streaming devices, televisions, and cables. It safeguards content by enforcing a verification step between the video player and the display.

This anti-piracy feature encrypts the signal when it creates a confirmed connection to prevent unauthorized recording of the content. This approach also makes it impossible for content owners to see their own work.

The video won’t play if it’s HDCP-protected yet one aspect of your setup isn’t HDCP-compliant (sometimes with an error message). As a result, many users with older equipment will be unable to view legally purchased content.

If the equipment isn’t HDCP-compliant, HDCP-compliant video will fall back to a lower resolution (typically 720p) if it isn’t HDCP-compliant. Devices other than a splitter rarely cause fallback mode, which is why splitters are such a good solution to this problem.

By accident, some low-cost splitters completely avoid HDCP. They shouldn’t be able to play protected video at all because cheap splitter makers didn’t bother paying for an HDCP license.

Because they activate Fallback mode, however, the content is lowered to a lesser resolution and continues to play normally. At least most of the time.
