  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...

Understanding USB Types: Appearance and Bandwidth

The Universal Serial Bus (USB) has become the cornerstone of modern connectivity. With a variety of types available, it’s essential to understand the differences, especially when it comes to their physical design and data transfer capabilities.


USB Type-A

Appearance: The most common USB type, USB Type-A, is recognized by its flat, rectangular shape. It’s the standard connector found on many devices.

Bandwidth:

USB 1.x: Up to 12 Mbit/s

USB 2.0: Up to 480 Mbit/s

USB 3.x: Up to 5 Gbit/s


USB Type-B

Appearance: USB Type-B ports are mostly used on printers and other peripheral devices. They have a square shape with slightly beveled corners on one end.

Bandwidth:

USB 1.x: Up to 12 Mbit/s

USB 2.0: Up to 480 Mbit/s

USB 3.x: Up to 5 Gbit/s


USB Type-C

Appearance: The newest type, USB Type-C, is known for its small, reversible connector. It’s becoming the new standard for modern devices.

Bandwidth:

USB 3.1/3.2: Up to 10 Gbit/s

USB4: Up to 40 Gbit/s


Micro-USB

Appearance: Micro-USB connectors are small and were commonly used in older smartphones and small electronic devices.

Bandwidth:

USB 2.0: Up to 480 Mbit/s


Mini-USB

Appearance: Mini-USB ports are smaller than USB Type-A but larger than Micro-USB. They were used in earlier mobile devices.

Bandwidth:

USB 2.0: Up to 480 Mbit/s


Thunderbolt 3 and 4 (USB-C)

Appearance: These use the USB-C port but offer higher data transfer rates and are often found on high-end laptops and devices.

Bandwidth:

Thunderbolt 3: Up to 40 Gbit/s

Thunderbolt 4: Up to 40 Gbit/s and more features
