Cable Matters DisplayPort 1.4 Cable -- Best for 1440p and 4K PC Gaming

Cable Matters DisplayPort 1.4 Cable -- Best for 1440p and 4K PC Gaming

DisplayPort 1.4 delivers 32.4 Gbps bandwidth, enough for 4K at 144Hz or 1440p at up to 240Hz without compression. The Cable Matters version uses braided nylon shielding to reduce EMI interference, which shows up as flickering on long cable runs. Latched connectors prevent accidental disconnects during intense sessions. This is the cable most PC gamers should use between a desktop GPU and a gaming monitor. It works with both Nvidia G-Sync and AMD FreeSync without requiring any settings adjustment beyond enabling adaptive sync in the GPU control panel.

HDMI 2.1, DisplayPort 1.4, and USB-C each have distinct advantages for gaming monitors. This guide picks the best cable and port combination for your GPU, monitor, and refresh rate target.

The cable connecting your GPU to your gaming monitor determines whether you unlock the full refresh rate, get adaptive sync, and avoid signal compression at high resolutions. Getting this wrong leaves frames and response time on the table. Here are the five best connection options for gaming monitors in 2026.

Belkin Ultra HD HDMI 2.1 Cable -- Best for Console and PC Mixed Use

HDMI 2.1 matches DisplayPort 1.4 bandwidth at 48 Gbps and is the only cable standard compatible with PS5 and Xbox Series X at 4K 120Hz. The Belkin Ultra HD version is certified to the 48 Gbps spec, which many cheaper HDMI 2.1 cables fail to sustain at 4K. If your setup involves swapping between a PC GPU and a console on the same monitor, an HDMI 2.1 cable keeps both devices running at full capability. VRR support over HDMI 2.1 is now consistent across major monitor brands.

Club3D DisplayPort 2.1 Cable -- Best Future-Proof Option

DisplayPort 2.1 triples the bandwidth of DP 1.4 to 80 Gbps, enabling 4K at 240Hz, 8K at 60Hz, or 1080p at 480Hz. Most current monitors cannot fully use DP 2.1 bandwidth, but high-refresh 4K monitors are arriving in 2026 from LG, Samsung, and Asus. Club3D is one of the few brands with cables certified to the full UHBR20 specification. If you plan to keep your GPU for three or more years and will upgrade your monitor, buying a DP 2.1 cable now avoids a bottleneck later. The cable itself is backward compatible with DP 1.4 monitors.

Anker USB-C to DisplayPort 1.4 Cable -- Best for Laptop Gamers

Anker USB-C to DisplayPort 1.4 Cable -- Best for Laptop Gamers

Gaming laptops and thin-and-light portables with Thunderbolt 4 or USB4 ports can output a full DisplayPort 1.4 signal over USB-C. The Anker USB-C to DP 1.4 cable supports 4K 60Hz and 1440p 144Hz while also carrying USB data, making it the cleanest one-cable solution for a laptop gaming desk. The aluminum connectors resist wear at the pivot point where cable and port meet. This cable also works with Mac and iPad Pro models that support DisplayPort Alt Mode over USB-C.

Amazon Basics HDMI 2.0 Cable -- Best Budget Secondary Screen

For secondary gaming monitors at 1080p 144Hz, HDMI 2.0's 18 Gbps bandwidth is sufficient and cables cost under ten dollars. The Amazon Basics HDMI 2.0 is not spectacular, but it is consistently well-built at this price and works reliably for secondary screens, capture card feeds, and HDMI 2.0 console setups. If your primary display uses DisplayPort and you want a secondary screen for Discord or a stream preview, HDMI 2.0 is all you need.

What to look for

What to consider

Check your GPU's available outputs first, then match the cable standard to your monitor's highest supported refresh rate. Most RTX 40-series and RX 7000-series cards include DisplayPort 2.1 and HDMI 2.1 ports. For 1440p 165Hz: any DP 1.4 cable works. For 4K 144Hz: DP 1.4 or HDMI 2.1. For 4K 240Hz: DP 2.1 required. Buy cables from brands that publish bandwidth certifications, not just claimed specs. A cable that looks correct but underperforms causes flicker and resolution drops that are easy to mistake for GPU or monitor defects.

FAQs

Is DisplayPort or HDMI better for gaming monitors?

DisplayPort 1.4 is generally better for PC gaming monitors because it supports higher refresh rates at 1440p and 4K and includes adaptive sync (G-Sync/FreeSync) natively. HDMI 2.1 matches DisplayPort bandwidth and is required for console gaming at 4K 120Hz on PS5 and Xbox Series X. For PC-only setups, DisplayPort 1.4 is the default choice.

Can USB-C replace DisplayPort for gaming?

USB-C with DisplayPort Alt Mode can carry a full 4K 60Hz or 1440p 144Hz signal over a single cable, which is ideal for laptop gaming setups that need one cable for power and video. It cannot currently match DisplayPort 1.4's full 32.4 Gbps bandwidth for 4K 144Hz. For desktop GPUs with dedicated DisplayPort outputs, a direct DP cable is still the better gaming connection.
