Nitro 5 AN515-45 has an HDMI 2.1 port capable of driving high-end external monitors. Hdmi port has Backward compatability mean You can connect HDMI 1.4 or 2.0 devices to your Acer Nitro 5 AN515-45, be aware that you will not be able to utilize the full capabilities of your laptop’s HDMI 2.1 port. For the best performance, especially if you're gaming or using high-resolution displays, it's recommended to use HDMI 2.0 or 2.1 cables and devices.

Key Points on HDMI 2.1

HDMI 2.1 introduces significant advancements over previous versions, enhancing video and audio capabilities:

• Increased Bandwidth: Supports up to 48 Gbps, allowing for higher resolutions and refresh rates, including 8K at 60Hz and 4K at 120Hz. It can theoretically handle up to 10K resolution with compression.
• Dynamic HDR: Enables scene-by-scene or frame-by-frame optimization of brightness, contrast, and color depth for a superior viewing experience.
• Enhanced Gaming Features:
  • Variable Refresh Rate (VRR): Reduces lag and screen tearing for smoother gameplay.
  • Auto Low Latency Mode (ALLM): Automatically switches to low-latency mode for gaming.
  • Quick Frame Transport (QFT): Minimizes latency for real-time applications.
• Enhanced Audio Return Channel (eARC): Supports advanced audio formats like Dolby Atmos, improving sound quality.
• Backward Compatibility: HDMI 2.1 ports are compatible with older HDMI versions, though with limited features

Key Points on Backward Compatibility

1. Resolution and Refresh Rate Limitations:
   • HDMI 1.4: Supports up to 4K resolution at 30Hz. This means that if you connect a 4K monitor using an HDMI 1.4 cable, you will be limited to 30 frames per second, which may not be ideal for gaming or fast-moving content.
   • HDMI 2.0: Supports up to 4K resolution at 60Hz. This is a better option for connecting to 4K monitors, providing a smoother experience, especially for gaming.
2. Audio Features:
   • Older HDMI versions may not support advanced audio formats available in HDMI 2.1, such as eARC (Enhanced Audio Return Channel) or object-based audio formats like Dolby Atmos.
3. Other Features:
   • Some features unique to HDMI 2.1, such as Variable Refresh Rate (VRR), Quick Frame Transport (QFT), and Auto Low Latency Mode (ALLM), will not be available when using older HDMI versions.

Tip- Avoid cheap cables and look for ones branded as HDMI 2.0 or 2.1 for best performance
