## How to Select 17.3 inch TFT LCD Displays For Purchase?
When selecting a 17.3 inch TFT LCD display, several factors need to be considered to ensure the display meets your requirements. Here is a clear and straightforward guide structured in a Q&A format to help you make an informed choice.
### 1. What are the key specifications to consider?
**Resolution:** Ensure the display offers the resolution you need. Higher resolutions provide clearer and more detailed images. Common resolutions for 17.3 inch displays include 1920x1080 (Full HD).
**Brightness:** Consider the brightness level of the display, measured in nits. A higher brightness level is beneficial for readability in various lighting conditions. Look for displays with at least 250 nits for general use.
**Contrast Ratio:** The contrast ratio determines the difference between the darkest blacks and the brightest whites. A higher contrast ratio improves image quality and color depth. Aim for a ratio of at least 1000:1.
### 2. How important is viewing angle?
Viewing angle is crucial if the display will be viewed from different positions. TFT LCD displays typically offer wide viewing angles which ensure that the image quality and colors remain consistent from different perspectives. Look for displays with at least 170-degree horizontal and vertical viewing angles.
### 3. Should I consider response time?
Yes, response time is essential, especially if the display will be used for gaming, video playback, or other fast-moving content. The response time, measured in milliseconds (ms), indicates how quickly a pixel can change colors. Lower response times (less than 10ms) help reduce motion blur and ghosting.
### 4. How do connectivity options affect my choice?
Ensure the display has the necessary connectivity options to match your devices:
- **HDMI:** For modern video and audio connections.
- **USB-C:** For versatile connectivity with power delivery.
- **VGA/DVI:** For older devices.
Check the ports available on your devices and select a display that offers compatible options.
### 5. What about the panel technology?
Different panel technologies impact image quality and performance:
- **IPS (In-Plane Switching):** Provides better color accuracy and wider viewing angles.
- **TN (Twisted Nematic):** Offers faster response times and is generally cheaper but with poorer color performance.
- **VA (Vertical Alignment):** Balances between IPS and TN with moderate response times and good color reproduction.
For general use, IPS is usually the best choice due to its superior color and viewing angles.
### 6. How should I approach the price vs. quality balance?
While budgeting is important, focus on the value rather than the lowest cost. Consider the display's durability, brand reputation, and warranty. It’s often worth paying a bit more for a quality product that meets all your requirements and offers reliable performance over time.
### 7. Do brand and customer reviews matter?
Yes, reputable brands and positive customer reviews can provide insights into product quality and customer satisfaction. Research brands known for their reliable LCD displays and browse customer feedback to identify any common issues or praised features.
### 8. Are there any additional features worth considering?
Other features may enhance your experience:
- **Anti-glare coating:** Reduces reflections from ambient light.
- **Touchscreen capability:** Useful for interactive applications.
- **Built-in speakers:** For convenience if external speakers are not preferable.
Ensure that additional features align with your specific needs.
## Conclusion.
Selecting a 17.3 inch TFT LCD display involves considering various factors such as resolution, brightness, contrast ratio, viewing angle, response time, connectivity options, panel technology, price vs. quality balance, brand reputation, and extra features. Following this guide will help you find a display that offers the best performance and meets your personal or professional needs.
