Key takeaways
- Primary use: DisplayPort is the PC monitor standard; HDMI 2.1 dominates TVs and consoles.
- Bandwidth: Both offer high bandwidth for 4K at high refresh; the exact ceiling depends on the DisplayPort version.
- Variable refresh: DisplayPort has the most mature PC variable refresh support; HDMI 2.1 added VRR that shines on consoles and TVs.
- Multi-monitor: DisplayPort supports daisy-chaining multiple displays via MST; HDMI does not.
- Audio return: HDMI 2.1 supports eARC for high-quality audio to soundbars and receivers; DisplayPort does not.
- Cable certification: Both require properly rated cables to hit their full spec; a cheap cable can cap performance.

Watch: DisplayPort vs HDMI 2.1 for Gaming — Video Review
Quick Verdict
For a desktop PC gaming monitor, DisplayPort is usually the better default, offering ample bandwidth for high resolutions and refresh rates and the most reliable variable refresh support on PC. HDMI 2.1 is the standard to use for TVs and consoles, where it excels at 4K high-refresh gaming and carries features like eARC. Both are excellent; choose DisplayPort for monitor-to-PC and HDMI 2.1 for TV or console setups.

DisplayPort for Gaming
DisplayPort is the connector of choice for PC gaming monitors. Modern DisplayPort 1.4 and newer versions provide the bandwidth to drive high resolutions at high refresh rates, and the standard has the longest, most reliable track record for PC variable refresh with both G-Sync and FreeSync. A certified DisplayPort cable like a VESA-certified DP 1.4 cord ensures you get the full refresh rate your monitor supports without dropouts.
DisplayPort also uniquely supports Multi-Stream Transport, letting you daisy-chain multiple monitors from a single port, and there are DisplayPort to dual HDMI adapters for driving several displays. For a desktop gamer connecting a high-refresh monitor to a PC, DisplayPort is the safe, high-performance default that avoids the refresh-rate caps that can catch out HDMI users on older versions.
HDMI 2.1 for Gaming
HDMI 2.1 transformed the interface for gaming, adding the bandwidth for 4K at 120Hz and features like variable refresh rate and auto low-latency mode that are ideal for console and TV gaming. If you play on a big-screen TV or a modern console, HDMI 2.1 is the port you want, since it carries both high-refresh video and, through eARC, high-quality audio back to a soundbar or receiver on a single cable.
On PC, HDMI 2.1 is also increasingly capable and is essential for connecting to TVs, but for desktop monitors DisplayPort often remains the more straightforward choice for guaranteed high-refresh PC gaming. When you do use HDMI 2.1, make sure you have a true HDMI 2.1 certified cable, as many older cables cannot carry the full bandwidth and will quietly limit your refresh rate.
Which Should You Buy?
- Use DisplayPort if: you are connecting a gaming monitor to a desktop PC.
- Use DisplayPort if: you want to daisy-chain multiple monitors or need the most mature PC variable refresh.
- Use HDMI 2.1 if: you game on a TV or a modern console at 4K high refresh.
- Use HDMI 2.1 if: you need eARC to send high-quality audio to a soundbar or receiver.
- Always use a certified cable: a properly rated DisplayPort or HDMI 2.1 cable is essential to hit full bandwidth.
Frequently Asked Questions
Is DisplayPort better than HDMI 2.1 for gaming?
For a desktop PC monitor, DisplayPort is often the better and more reliable choice for high-refresh gaming and multi-monitor setups. HDMI 2.1 is better for TVs and consoles. Neither is universally superior; the right one depends on your devices.
Do I need an HDMI 2.1 cable specifically?
Yes, to get the full HDMI 2.1 bandwidth for 4K high-refresh gaming you need a certified Ultra High Speed HDMI 2.1 cable. Older HDMI cables can connect but will cap your resolution or refresh rate, silently limiting performance.
Can I use both ports at the same time?
Yes. Many gamers run one monitor over DisplayPort and another over HDMI, or connect a PC to a monitor via DisplayPort and a TV via HDMI. Just make sure each connection uses a cable rated for the resolution and refresh you want.
Why is my refresh rate capped over HDMI?
Usually because either the cable is not HDMI 2.1 rated or the port on your GPU or monitor is an older HDMI version. Check both ends support HDMI 2.1 and use a certified cable, or switch to DisplayPort for guaranteed high refresh on PC.
Final Verdict
DisplayPort and HDMI 2.1 are both excellent modern interfaces, and the right choice comes down to your setup. For a desktop PC gaming monitor, DisplayPort is the reliable default with the best variable refresh support and multi-monitor flexibility. For TVs and consoles, HDMI 2.1 is the standard, delivering 4K high-refresh gaming and eARC audio. Whichever you use, invest in a properly certified cable so you actually get the performance your hardware promises.
