No—not automatically. A 1000Hz monitor needs a connection that supports its specific resolution, refresh rate and color depth, but that connection is not always DisplayPort. The monitor’s input, your graphics card’s output, the cable and the selected display mode must all support the same signal.
What determines whether a connection can run at 1000Hz?
Refresh rate is only one part of the signal. Resolution and color depth affect the bandwidth required, too. Intel’s guide explains that the signal’s bandwidth depends on those three elements and advises checking that the requested bandwidth fits within the cable’s effective bandwidth: Intel’s bandwidth guide.

That means a cable marked for a fast interface cannot create a mode the monitor or graphics card does not support. The monitor must accept the chosen timing on that particular input, the GPU must be able to send it from the connected output, and the cable must carry it. Adapters and docks add more links that can limit the signal.

Does it have to be DisplayPort?
No. Check the maximum supported resolution, refresh rate and color depth for each input on the exact monitor model. Do not assume that DisplayPort supports 1000Hz simply because it is DisplayPort, or that HDMI cannot support it because it is HDMI.

Support DP, DP++ modes, backward compatible 2.0/1.4/1.3/1.2
For example, LG’s listing for the 25G590B-B describes an FHD gaming monitor rated for up to 1000Hz native and 1100Hz overclocked, and names both DisplayPort 2.1 UHBR20 and HDMI 2.1. The listing does not provide an input-by-input refresh-rate table, so it does not establish which connection reaches 1000Hz. Check the full official specification or manual before choosing a port: LG 25G590B-B product listing.
What cable should you use?
Use a cable whose certified capability matches the signal path specified by the monitor and GPU documentation. If the documented DisplayPort mode calls for UHBR20, investigate a VESA-certified DP80 or DP80LL cable and confirm compatibility with both devices. VESA describes DP80/DP80LL cables for UHBR20; its FAQ also advises checking the vendor’s packaging or product information for supported features: VESA DisplayPort FAQ.

VESA says DisplayPort 2.1b has a maximum payload of 77.37 Gbps. That is a standard capability, not proof that an unspecified monitor, input or graphics card can run at 1000Hz. Cable certification is useful only when the rest of the connection supports the target mode.

| HDMI 2.1 | 42.67 Gbps |
| DisplayPort 1.3/1.4 | 25.92 Gbps |
| DisplayPort 2.0 | 77.37 Gbps |
These figures come from Intel’s bandwidth guide. VESA separately gives DisplayPort 2.1b a maximum payload of 77.37 Gbps and describes DP80/DP80LL UHBR20 cables as providing up to 80 Gbps throughput. For DP80LL active cables, VESA cites lengths up to three meters. These standard and cable figures do not, on their own, establish whether a particular 1000Hz monitor will work at its maximum on a given input.

How to check your setup
- Read the monitor’s exact manual or full specification. Look for the maximum resolution, refresh rate and color depth supported by each input. If the documentation does not identify the maximum for a port, do not infer it from the connector type.
- Check the graphics card’s output specifications. Confirm support for the same resolution, refresh rate, color depth and interface mode.
- Match the cable to the documented link. Check its certification and rated capability; for a specified UHBR20 DisplayPort link, look into certified DP80/DP80LL cables.
- Connect directly while troubleshooting. Remove docks or adapters where possible, then select the supported refresh rate in your operating system and check for graphics-driver updates.
- Check the application’s limits. Even when the desktop is set to 1000Hz, a game may not render at that frame rate. LG notes that realized performance on its 25G590B-B can depend on PC specifications, game-specific frame-rate limitations, operating-system version and graphics drivers.
