GTG and MPRT specs in monitors - why they lie you about them

  GTG vs. MPRT: What These Monitor Specs Really Mean (and Why They’re Often Misleading) When you shop for a gaming monitor, you’re bombarded with numbers: 1 ms response time , 0.5 ms MPRT , 165 Hz , 240 Hz , 360 Hz . It all sounds impressive — but most of it is marketing smoke and mirrors. Two of the most misunderstood specs are GTG (Gray‑to‑Gray) and MPRT (Moving Picture Response Time) . They both relate to motion clarity, yet they measure completely different things. Understanding the difference helps you avoid buying a monitor based on inflated numbers and instead choose one that actually fits how you use your PC. What Is GTG (Gray‑to‑Gray)? GTG measures how fast a pixel can change from one shade of gray to another . This is a pixel transition time , not a motion clarity measurement. Key points about GTG It measures static pixel transitions. It’s usually measured under ideal conditions with aggressive overdrive. Manufacturers often quote the fastest transition, not the averag...

HDMI vs Display Port

 


DisplayPort vs HDMI: Understanding the Differences

When it comes to connecting your computer to a monitor or television, the two most common interfaces you’ll encounter are DisplayPort and HDMI. Both serve the purpose of transmitting audio and video signals, but they have distinct features and capabilities that may make one more suitable than the other depending on your needs.

Physical Design

DisplayPort typically features a 20-pin connector with an asymmetrical shape, often including a latch to prevent accidental disconnections. HDMI, on the other hand, has a 19-pin connector with a symmetrical shape, but usually lacks a locking mechanism, which can lead to loose connections over time.

Version History and Capabilities

HDMI

HDMI 1.4: Supports up to 4K resolution at 24Hz or 30Hz, and 1080p at 120Hz.

HDMI 2.0: Increases support to 4K at 60Hz, with later versions adding HDR support.

HDMI 2.1: Offers up to 10K resolution at 120Hz, enhanced audio return channel (eARC), and variable refresh rate (VRR) capabilities.

DisplayPort

DisplayPort 1.4: Supports 4K at 120Hz, 8K at 60Hz, and includes support for HDR.

DisplayPort 2.0: Significantly increases bandwidth, supporting 8K at 60Hz and 10K resolutions, with a higher maximum bandwidth compared to HDMI 2.1.

Use Cases

HDMI is widely used for TVs and gaming consoles, providing a simple solution for high-definition audio and video transmission. It’s also commonly found in laptops and PCs.

DisplayPort is often the preferred choice for computer monitors and professional displays, especially for users who require high refresh rates and resolutions for tasks such as gaming or detailed graphical work. It also allows for daisy-chaining multiple monitors from a single port, a feature not available with HDMI.

Conclusion

The choice between DisplayPort and HDMI will largely depend on the devices you’re using and your specific requirements. For high-performance gaming or professional displays, DisplayPort might be the better option due to its higher refresh rates and resolutions. However, for general use, such as watching TV or standard office work, HDMI is more than sufficient.


Remember to check the specifications of your devices to ensure compatibility and to select the appropriate cable and port that meets your needs.
