Yes, DisplayPort can run 144Hz — and has been able to since version 1.0 at 1080p. DisplayPort 1.2 and above handles 144Hz reliably at 1080p and 1440p, while DisplayPort 1.4 and 2.0/2.1 extend that to 4K.
- You use DisplayPort 1.2 or higher for 1080p or 1440p at 144Hz
- You use DisplayPort 1.4 with DSC enabled for 4K at 144Hz
- Your GPU and monitor both support the required bandwidth
- Refresh rate is set correctly in your GPU control panel
- You are using DisplayPort 1.0 or 1.1 above 1080p
- Your monitor or GPU does not support DSC for 4K 144Hz on DP 1.4
- Display settings default to 60Hz and are not manually corrected
- Driver issues prevent the OS from seeing available refresh rates
Which DisplayPort Version Do You Need?
Not all DisplayPort versions deliver the same bandwidth. Matching your cable and port version to your target resolution and refresh rate is the most important step.
| Setup | Works? | Need | Note |
|---|---|---|---|
| 1080p 144Hz | Yes | DP 1.0+ | Supported since early versions |
| 1440p 144Hz | Yes | DP 1.2+ | Most common gaming setup |
| 4K 144Hz | Yes | DP 1.4 + DSC | Compression required on 1.4 |
| 4K 144Hz native | Yes | DP 2.0/2.1 | No compression needed |
| 1080p 240Hz | Yes | DP 1.3+ | Competitive gaming use case |
How to Enable 144Hz on DisplayPort
Plugging in the cable is not enough — Windows often defaults to 60Hz even on a 144Hz monitor.
- On NVIDIA: open NVIDIA Control Panel → Change resolution → select your refresh rate
- On AMD: open Radeon Software → Display → set refresh rate manually
- On Windows: Settings → System → Display → Advanced display → Choose refresh rate
If 144Hz does not appear as an option, update your GPU drivers and check that the monitor firmware is current. The VESA DisplayPort specification confirms the bandwidth limits for each version.
DisplayPort vs HDMI for 144Hz
HDMI can reach 144Hz in some configurations, but DisplayPort is the more consistent choice for high refresh rates. If you are connecting a PC to a monitor, DisplayPort is almost always the better option. For TV connections or console setups, see whether USB-C to HDMI works for your setup or check whether your USB-C port supports video output if you are on a laptop.
Common Reasons 144Hz Is Not Showing Up
- Cable is DisplayPort but the port on the GPU is an older version
- Using a passive adapter (e.g. DisplayPort to DVI) — these cap out below 144Hz
- DSC is not enabled on the monitor for 4K 144Hz via DP 1.4
- Refresh rate was never changed from the 60Hz default in Windows
Bottom line: DisplayPort can absolutely run 144Hz — you just need DisplayPort 1.2 or higher for 1440p, and DisplayPort 1.4 or 2.1 for 4K. Once the cable is connected, always verify the refresh rate manually in your GPU control panel rather than assuming Windows set it correctly.
