How to Switch Monitor From HDMI to Displayport
Honestly, the sheer amount of garbage advice online about connecting displays is enough to make you want to throw your whole setup out the window. I’ve spent way too many hours fumbling with cables, convinced I was doing something wrong when, in reality, the product or the ‘expert’ advice was just plain bad.
Maybe you’re in the same boat. You’ve got a new monitor, or you’re trying to get that high refresh rate working, and you’re staring at two ports: HDMI and DisplayPort. Which one do you use? And how do you switch monitor from HDMI to DisplayPort if you’ve already got something plugged in?
It’s not always as simple as just plugging in the other cable. Sometimes, you’ve got to tell your computer, and even the monitor itself, what you want it to do. This whole process can feel like a digital labyrinth if you don’t know the common pitfalls.
The Glorious Truth About Displayport vs. HDMI
Look, everyone talks about DisplayPort being the ‘superior’ connection for gaming and high refresh rates. And yeah, for the most part, they’re right. But it’s not some magic wand that instantly makes your games look like they were rendered by angels. For years, I stuck with HDMI because it was what I knew, what my old graphics card had plenty of, and honestly, the sheer variety of HDMI cables felt less overwhelming than the DisplayPort options.
My first real ‘oh crap’ moment came when I bought a 144Hz monitor. Plugged it in via HDMI, set the resolution, and… maxed out at 60Hz. I spent probably three evenings fiddling with settings, convinced I’d bought a dud monitor. Turns out, my particular HDMI cable, which I’d sworn was ‘high-speed’ (cost me about $30, I was so proud), just didn’t have the bandwidth for anything beyond standard refresh rates. That was a hard lesson: not all cables are created equal, and sometimes the port itself is the limiting factor. DisplayPort, on the other hand, was built from the ground up for higher bandwidths and more advanced features.
So, how to switch monitor from HDMI to DisplayPort? It’s usually not about swapping cables mid-session and expecting magic. It’s more about understanding what each port does and how to properly configure your system to use the one you want.

Physical Connection: The Obvious First Step
This sounds insultingly simple, I know. But you’d be amazed how many people skip this or do it wrong. First, power down your computer and your monitor. Seriously. While modern ports are generally hot-pluggable, it’s just good practice, especially if you’re dealing with older hardware or just want to avoid any potential weirdness.
Now, locate the DisplayPort output on your graphics card (or motherboard if you’re using integrated graphics) and the DisplayPort input on your monitor. They look pretty similar, but DisplayPort has a slightly L-shaped connector with a tab on one side that you need to push down to release. HDMI is a more straightforward trapezoid shape.
Plug one end of your DisplayPort cable firmly into the graphics card and the other end into the monitor. Make sure it clicks or seats properly. Sometimes, a loose connection is all it takes to cause headaches. I once spent an hour troubleshooting a no-signal issue, only to find the cable had worked its way slightly out of the monitor port.
Now, power your monitor back on first, then boot up your computer. Most of the time, your computer will automatically detect the new connection and display the desktop. If not, that’s where the real fun begins.

Telling Your Computer What to Do (the Software Side)
This is where most people get tripped up when they ask ‘how to switch monitor from HDMI to DisplayPort.’ Your computer doesn’t just ‘know’ you want to use DisplayPort. You might need to tell it, especially if you have multiple displays connected or if Windows decides it likes HDMI better for some reason. (See Also: How To Put 144hz Monitor At 144hz )
For Windows Users:
Right-click on your desktop and select ‘Display settings.’ Scroll down to the ‘Multiple displays’ section. Here, you’ll see a list of all detected displays. If your monitor isn’t showing up or is showing up as ‘Generic PnP Monitor’ but not functioning correctly, you might need to click ‘Detect’ under the ‘Multiple displays’ dropdown, though this is becoming less common.
More importantly, you can select your monitor from the diagram at the top and then choose whether to ‘Extend these displays,’ ‘Duplicate these displays,’ or ‘Show only on 1’/’Show only on 2.’ Make sure the correct monitor is selected and that you’re extending your desktop if you want to use it as a separate screen, or duplicating if you want the same content on both. If you only want to use the DisplayPort monitor, you can choose ‘Show only on 2’ (assuming it’s number 2) and then disconnect the HDMI.
If your monitor supports higher refresh rates and they aren’t showing up, select your monitor, scroll down, and click ‘Advanced display settings.’ From there, select your monitor again, and under ‘Refresh rate,’ choose the highest available option. This is where DisplayPort often shines, allowing for 120Hz, 144Hz, 240Hz, or even higher, something many HDMI versions struggle with.
For macOS Users:
Go to System Settings (or System Preferences on older macOS versions) > Displays. You should see your connected displays. If you have multiple, you can arrange them by dragging their representations. To change the refresh rate, click on your monitor, and look for a ‘Refresh Rate’ dropdown. Again, DisplayPort often gives you access to higher refresh rates than HDMI.
If your Mac is being particularly stubborn, sometimes a simple restart after plugging in the DisplayPort cable does wonders. I’ve found Macs can be a bit finicky about detecting new displays on the fly compared to Windows machines.
It’s like teaching a toddler a new trick; sometimes you have to repeat yourself, and sometimes they just decide they don’t want to do it today. You might even need to go into your graphics card’s control panel – NVIDIA Control Panel or AMD Radeon Software – to force settings or check for driver updates. Outdated graphics drivers are the silent killer of smooth display transitions, believe me.

Monitor Settings: The Unsung Hero
Here’s a dirty little secret: sometimes, the monitor itself is the bottleneck. Every monitor has its own internal settings menu, usually accessed via buttons on the bezel or back of the display. You need to ensure the monitor is set to accept a DisplayPort signal correctly.
Dig into your monitor’s OSD (On-Screen Display) menu. Look for options like ‘Input Select,’ ‘Source,’ or ‘Signal Type.’ Make sure it’s set to ‘Auto’ or specifically ‘DisplayPort.’ If you’re trying to get higher refresh rates or specific features like G-Sync or FreeSync working, there might be a separate setting for that, often labeled ‘DP Version’ (e.g., DP 1.2, DP 1.4) or related to adaptive sync technologies. Setting the DP Version correctly is vital. For example, if you have a 4K monitor and want 144Hz, you’ll need DP 1.4. Trying to run it on DP 1.2 might limit you to 60Hz, similar to my HDMI cable debacle.
I remember my first 4K HDR monitor. It looked washed out and the colors were all wrong on HDMI. I spent days tweaking software settings. It wasn’t until I stumbled upon a forum post from about 2017 that someone mentioned checking the ‘HDMI Deep Color’ setting *on the monitor itself*. Changed it from ‘Off’ to ‘On’, and BAM! The colors popped. The monitor’s internal settings are often overlooked, like finding a hidden cheat code in a video game. (See Also: How To Switch An Acer Monitor To Hdmi )
This is also where you might need to toggle specific features. Some monitors require you to explicitly enable ‘DisplayPort 1.4’ or ‘HDR’ in their menus before the system can even see those capabilities. It’s not just about plugging in; it’s about telling the monitor to be ready for what you’re throwing at it.

Troubleshooting: When Things Go Sideways
So, you’ve connected the DisplayPort cable, you’ve checked Windows/macOS, and you’ve fiddled with the monitor settings. Still nothing? Don’t panic. This is where the real detective work begins.
Check the Cable: Seriously, try a different DisplayPort cable. Not all cables are created equal, and a faulty or low-quality cable is a surprisingly common culprit for no signal or limited refresh rates. I keep a known-good, certified DP 1.4 cable around just for this reason. They often have thicker shielding and better connectors.
Driver Issues: Ensure your graphics card drivers are up to date. Visit NVIDIA or AMD’s website and download the latest drivers. Sometimes, a driver update can fix compatibility issues that prevent proper detection of DisplayPort connections or specific monitor features. A clean installation, where you remove old drivers before installing new ones, can be particularly effective.
Graphics Card Output: If you have multiple DisplayPort outputs on your graphics card, try a different port. Occasionally, a single port can develop a fault. This is less common on newer cards but can happen.
Monitor Firmware: This is a long shot, but some high-end monitors receive firmware updates that can address connectivity issues. Check the manufacturer’s support website for your specific monitor model to see if any updates are available and how to apply them. It usually involves downloading a file to a USB drive and plugging it into the monitor.
The ‘One Monitor’ Test: If you have multiple monitors connected, try disconnecting everything except the one you want to use via DisplayPort. Sometimes, the interaction between different displays and connection types can cause conflicts. Once the DisplayPort monitor is working correctly, then try reconnecting your other displays.
The whole process of trying to get a display working perfectly can feel like you’re training a wild animal. You try one thing, it snaps. You try another, it seems okay, then it runs off. It takes patience, and sometimes a bit of trial and error, to get everything singing in harmony.

Common Questions About Switching Ports
Do I Need a Special Cable to Switch Monitor From HDMI to Displayport?
Yes, you absolutely need a DisplayPort cable. You cannot use an HDMI cable for a DisplayPort connection, or vice versa, without an adapter. For higher resolutions and refresh rates, especially for gaming, ensure your DisplayPort cable is certified for the version you need (e.g., DP 1.4 for 4K 144Hz).
Can I Have Both HDMI and Displayport Connected to My Pc at the Same Time?
Yes, you absolutely can. Most modern graphics cards have multiple display outputs, and you can connect several monitors using a mix of HDMI and DisplayPort cables. Your operating system will then allow you to configure how these multiple displays work together (extend, duplicate, etc.). (See Also: How To Monitor My Sleep With Apple Watch )
Will My Monitor Automatically Switch to Displayport If It’s Plugged in?
Some monitors have an ‘auto-detect’ input feature, so they might switch automatically. However, this isn’t universal, and it’s often more reliable to manually select the DisplayPort input via the monitor’s on-screen display (OSD) menu, or to ensure your computer is configured to output via DisplayPort in its display settings.
What If My Computer Only Has HDMI Ports?
If your computer lacks a DisplayPort output, you can’t directly connect to a monitor’s DisplayPort input using a simple cable. You would need an ‘HDMI to DisplayPort adapter,’ but be aware that these are typically one-way adapters and often active converters that require external power. They also might not support high refresh rates or certain features, so research specific adapter capabilities carefully.
Is Displayport Better Than HDMI for Gaming?
Generally, yes. DisplayPort supports higher bandwidth, which means it can handle higher resolutions and refresh rates more easily than most HDMI standards. It also supports adaptive sync technologies like G-Sync and FreeSync natively, which are crucial for smooth, tear-free gaming. While newer HDMI versions (like 2.1) are catching up, DisplayPort is still often the preferred choice for serious PC gamers.

The Adapter Gamble: When Ports Don’t Match
Sometimes, you’re stuck. Your shiny new monitor screams for DisplayPort, but your trusty old graphics card only has HDMI outputs. Or maybe you’ve got a DisplayPort on your PC but only HDMI inputs on your monitor. This is where adapters or converters come into play, and frankly, it’s a minefield.
You’ll see ‘HDMI to DisplayPort adapters’ and ‘DisplayPort to HDMI adapters.’ Pay close attention: they are NOT interchangeable. An HDMI source to a DisplayPort display typically requires an *active adapter* that converts the signal. These usually need external power, often via USB, and can be pricey. They also have limitations; not all active HDMI-to-DisplayPort adapters will support 4K at 120Hz or FreeSync. I once bought one for around $40, only to find out it capped me at 1080p 60Hz. Felt like I’d bought a participation trophy for a technology race I wasn’t even in.
Conversely, a DisplayPort source to an HDMI display is often simpler, sometimes just requiring a passive adapter if your source (graphics card) can output the correct signal type. However, for higher resolutions and refresh rates, you’ll still want a quality, certified adapter. Always check the adapter’s specifications against your monitor’s capabilities before buying. Don’t just grab the cheapest thing; it’s an investment in not pulling your hair out later.
It’s a bit like trying to fit a square peg in a round hole. Sometimes you can make it work with a specialized tool, but it’s never going to be as clean or as efficient as using the right-shaped peg in the first place.
| Connection Type | Typical Use Case | Bandwidth/Features | My Verdict |
|---|---|---|---|
| HDMI | General use, older monitors, TVs, consoles | Varies by version (HDMI 1.4, 2.0, 2.1). Good for 4K 60Hz, but higher refresh rates at 4K can be limited or require HDMI 2.1. | Reliable and ubiquitous, but often not the first choice for high-end PC gaming due to refresh rate limitations on older versions. |
| DisplayPort | PC gaming, high refresh rate monitors, multi-monitor setups | Generally higher bandwidth than comparable HDMI versions. Supports higher refresh rates at high resolutions, G-Sync/FreeSync natively. DP 1.4 is common and robust. | The go-to for serious PC enthusiasts and gamers. Handles demanding visual scenarios better. If your monitor and GPU support it, use DisplayPort. |
| Active Adapters (e.g., HDMI to DP) | Bridging incompatible ports on PC/Monitor | Highly variable. Depends on adapter quality and power. Often a compromise on refresh rate or resolution. | A necessary evil when you have no choice. Research thoroughly and expect a potential performance hit or added cost. Not ideal. |

Verdict
Figuring out how to switch monitor from HDMI to DisplayPort isn’t just about plugging in a different cable; it’s about understanding the language your hardware speaks. It involves a bit of detective work, sometimes in the operating system, sometimes buried deep in your monitor’s menu.
Don’t get discouraged if it doesn’t work instantly. The most common issues boil down to a few key areas: the cable itself, outdated drivers, or a setting that’s just not quite right on the monitor or in your PC’s display configuration. I’ve found that systematically checking each one, almost like a checklist, usually gets you there.
Ultimately, if you’re aiming for high refresh rates, smoother gameplay, or just a more stable connection for demanding visual tasks, making the switch to DisplayPort is often worth the small hassle. Just remember that not all cables are equal, and sometimes the simplest solution is the one you’ve overlooked for hours.
If you’re still having trouble after trying these steps, double-check your monitor’s manual and your graphics card’s specifications. Sometimes, the hardware just might not support the combination you’re trying to achieve without a specific adapter, and even then, there can be limitations.
