The Quick Answer

Use HDMI 2.1 if you:

  • • Game on PS5, Xbox Series X, or both PC and console
  • • Need one cable for video, audio, and ARC/eARC
  • • Run 4K at up to 120 Hz (most common gaming scenario)

Use DisplayPort 2.0 if you:

  • • Game exclusively on PC with a modern GPU
  • • Want 4K 240 Hz+ without compression
  • • Plan to use 8K displays or daisy-chain monitors

Understanding Bandwidth: Why It Matters

Bandwidth determines the maximum amount of display data that can be pushed through a cable per second. Higher bandwidth means higher resolutions at higher refresh rates without needing compression. Here is what each standard can handle natively.

Bandwidth Requirements by Resolution & Refresh Rate

Resolution @ Refresh Rate Bandwidth Needed HDMI 2.1 (48 Gbps) DP 2.0 UHBR 20 (80 Gbps)
1080p @ 240 Hz ~14.9 Gbps Native Native
1440p @ 165 Hz ~17.8 Gbps Native Native
1440p @ 240 Hz ~25.9 Gbps Native Native
1440p @ 360 Hz ~38.8 Gbps Native Native
4K @ 60 Hz ~17.8 Gbps Native Native
4K @ 120 Hz ~35.6 Gbps Native Native
4K @ 144 Hz ~42.7 Gbps DSC needed Native
4K @ 240 Hz ~71.1 Gbps DSC needed Native
8K @ 60 Hz ~71.1 Gbps DSC needed Native

Note: "DSC needed" means Display Stream Compression is required. DSC is visually lossless -- most users cannot distinguish DSC-compressed output from native. Both HDMI 2.1 and DP 2.0 support DSC.

Variable Refresh Rate (VRR) Support

HDMI 2.1 VRR

  • HDMI Forum VRR: Built into the HDMI 2.1 spec. Supported by PS5, Xbox Series X, and most modern GPUs.
  • AMD FreeSync over HDMI: Many monitors support FreeSync Premium/Premium Pro via HDMI 2.1.
  • ALLM (Auto Low Latency Mode): Automatically switches the display to game mode when gaming content is detected.
  • NVIDIA G-Sync over HDMI: NVIDIA supports G-Sync Compatible over HDMI 2.1 on RTX 30/40/50 series, but full G-Sync (hardware module) typically requires DisplayPort.

DisplayPort 2.0 VRR

  • Adaptive-Sync: Native part of the DisplayPort standard since DP 1.2a. Mature, widely supported by AMD and NVIDIA GPUs.
  • NVIDIA G-Sync Compatible: Full support for G-Sync Compatible over DisplayPort on all modern NVIDIA GPUs.
  • G-Sync Ultimate (hardware): Monitors with dedicated G-Sync modules require DisplayPort -- they do not work over HDMI.
  • No console support: VRR over DisplayPort is PC-only since no consoles have DP outputs.

Console Compatibility Guide

This is the deciding factor for many buyers. If you use a console, HDMI is your only option. Here is what each console supports.

Console HDMI Version Max Output VRR DisplayPort
PlayStation 5 HDMI 2.1 4K @ 120 Hz Yes (HDMI VRR) No
Xbox Series X HDMI 2.1 4K @ 120 Hz Yes (HDMI VRR + FreeSync) No
Xbox Series S HDMI 2.1 1440p @ 120 Hz Yes (HDMI VRR + FreeSync) No
Nintendo Switch 2 HDMI 2.1 4K @ 60 Hz (expected) TBD No

Console Buyer Takeaway

If you own or plan to own any gaming console, your monitor must have at least one HDMI 2.1 port. HDMI 2.0 will limit you to 4K 60 Hz or 1440p 60 Hz, missing out on the 120 Hz gaming modes that define the current console generation. Both the LG 27GP950-B and Samsung Odyssey Neo G7 include HDMI 2.1 ports specifically for this purpose.

Cable Buying Guide: Getting the Right Cable

HDMI 2.1 Cables

What to Buy

Look for "Ultra High Speed HDMI" certification and the official hologram label. These cables are rated for 48 Gbps and support all HDMI 2.1 features.

What to Avoid

Do not buy generic "HDMI 2.1" cables without the Ultra High Speed certification. Many cheap cables claiming HDMI 2.1 only deliver HDMI 2.0 bandwidth (18 Gbps).

Recommended Lengths

  • • Under 3 m: Standard passive cable works fine
  • • 3-5 m: Look for active or fiber-optic cable
  • • Over 5 m: Fiber-optic HDMI required

Expected Cost

$8-15 for 2 m certified cable; $30-60 for 5 m active cable

DisplayPort 2.0 Cables

What to Buy

Look for VESA-certified DP40 (40 Gbps) or DP80 (80 Gbps) cables. The DP80 cable supports the full UHBR 20 bandwidth for maximum future-proofing.

What to Avoid

Standard DisplayPort 1.4 cables (HBR3 rated) will not deliver DP 2.0 bandwidth. They are physically compatible but will limit your bandwidth to 32.4 Gbps.

Recommended Lengths

  • • Under 2 m: Standard DP80 passive cable works
  • • 2-4 m: DP40 cable recommended (80 Gbps harder at length)
  • • Over 4 m: Active or fiber-optic cable required

Expected Cost

$15-25 for 2 m DP80 cable; $40-80 for active long cable

Which Connection Should You Choose?

Choose HDMI 2.1 if you:

  • • Play on PS5, Xbox Series X, or any gaming console
  • • Need a single cable for both video and high-quality audio (eARC)
  • • Game at 4K 120 Hz or lower -- HDMI 2.1 handles this natively
  • • Connect to a TV or AV receiver in a living room setup
  • • Want the widest device compatibility (consoles, PCs, streaming boxes, laptops)

Choose DisplayPort 2.0 if you:

  • • Game exclusively on a PC with a modern NVIDIA or AMD GPU
  • • Want 4K 240 Hz or 8K 60 Hz without any compression
  • • Need to daisy-chain multiple monitors from a single output
  • • Use a G-Sync Ultimate monitor (hardware G-Sync requires DP)
  • • Want maximum future-proofing for next-gen displays

Best approach: Get a monitor with both

  • • Use DisplayPort for your PC (best bandwidth, G-Sync support)
  • • Use HDMI 2.1 for your console (only option, works perfectly)
  • • Switch inputs as needed -- no adapter hassles

Our 2026 Recommendation

For the vast majority of gamers, HDMI 2.1 is the more important port to have. It covers consoles, supports 4K 120 Hz natively, and works with every modern device. DisplayPort 2.0 offers more headroom for extreme resolutions and refresh rates, but adoption in monitors and GPUs is still ramping up. The ideal monitor in 2026 has both HDMI 2.1 and DisplayPort -- use DP for your PC and HDMI for everything else.

DisplayPort 2.0 vs 1.4: Is the Upgrade Worth It?

Many current monitors still use DisplayPort 1.4 rather than 2.0. Here is a quick comparison to help you decide if DP 2.0 is necessary for your setup.

Feature DP 1.4 DP 2.0
Max Bandwidth 32.4 Gbps 80 Gbps
4K 144 Hz (native) DSC required Native
4K 240 Hz DSC required Native
8K support DSC at 30 Hz Native at 60 Hz
Monitor Availability Very common Growing in 2026
GPU Support All modern GPUs RTX 50-series, RX 8000+

Verdict: For 1440p and 4K 120 Hz gaming, DP 1.4 with DSC is perfectly adequate. DP 2.0 becomes relevant if you want 4K 240 Hz without compression, plan to use an 8K display, or want to daisy-chain multiple high-res monitors. Most gamers do not need DP 2.0 today, but it is a nice future-proofing bonus.
