### **Pros and Cons of buying a Sony AP-P397AM-1 (KD-55A85/KD-48A9) TV with Power Supply (Model: 2955063901 / 100640312)**

#### **Pros**

1. **High-Quality Display** The A85 series features Sony s **X1 Extreme processor**, delivering excellent color accuracy, HDR (HDR10, HLG), and dynamic contrast for a premium viewing experience. The **4K UHD resolution** ensures sharp image quality, ideal for movies, gaming, and streaming.

2. **Strong Gaming Performance** The TV supports **HDMI 2.1**, **120Hz refresh rate**, and **VRR (Variable Refresh Rate) with FreeSync Premium**, making it suitable for **PS5, Xbox Series X/S, and high-end gaming PCs**. The **low input lag** enhances responsiveness.

3. **Sony s Image Processing** The **XR processor** enhances motion clarity, reduces motion blur, and improves upscaling for non-4K content. The **Acoustic Surface Audio ** system provides immersive sound without external speakers.

4. **Smart TV Features** The **Google TV OS** offers a user-friendly interface with access to **Netflix, YouTube, Prime Video, and more**. Voice control via **Google Assistant** and **Siri** adds convenience.

5. **Durable Build & Design** The **slim bezel, premium finish, and sturdy construction** make it a stylish addition to any room. The **wall-mounting options** (VESA 600x400) are also available.

6. **Reliable Power Supply** The included **Sony-branded power supply (2955063901 / 100640312)** is designed to match the TV s specifications, ensuring stable power delivery and reducing the risk of damage from incompatible adapters.

---

#### **Cons**

- **Less perfect blacks** (though still deep compared to LED-LCD).

- **Potential burn-in risk** (though less severe than OLED).

- **Lower peak brightness** than some OLED TVs in very bright rooms.

2. **Limited HDR Performance** While it supports **HDR10 and HLG**, the **HDR contrast ratio is not as extreme as OLED**, meaning HDR content may not look as impactful in dimly lit rooms.

3. **No Dolby Vision** The TV uses **HLG (Hybrid Log-Gamma)** instead of **Dolby Vision**, which is a drawback for HDR content that relies on Dolby Vision (e.g., some Netflix, Disney , and gaming HDR).

4. **Average Local Dimming** The **VA panel has moderate local dimming**, which can lead to **ghosting or blooming in dark scenes** (though better than basic LED TVs).

5. **No Built-in Sound Enhancements** While the **Acoustic Surface Audio ** is decent, it **cannot compete with soundbars or AV receivers** for the best audio experience.

6. **Potential for Overheating** Some users report that the TV can get **warm during prolonged use**, especially in poorly ventilated spaces. Proper placement (away from walls) is recommended.

7. **Google TV Limitations** While Google TV is user-friendly, it **lacks some third-party app exclusives** found on other smart TV platforms (e.g., TCL s Roku TV or Samsung s Tizen).

8. **Price Sensitivity** If budget is a concern, **entry-level OLEDs (like LG C2 or Samsung QN90C)** or **high-end LED TVs (like TCL 6-Series)** may offer **better value** depending on specific needs.

---

### **Conclusion**

The **Sony KD-55A85/KD-48A9 (AP-P397AM-1) with the included power supply** is a **solid mid-range 4K TV** that excels in **gaming, HDR, and overall picture quality** while maintaining a **premium build**. It is an **ideal choice for:**

- **Gamers** (thanks to HDMI 2.1 and VRR).

- **Movie enthusiasts** who prioritize **color accuracy and HDR**.

- **Consumers who prefer Sony s processing** over raw OLED contrast.

- **Those who want a reliable, branded power supply** included.

However, if **perfect blacks, Dolby Vision, or extreme HDR contrast** are non-negotiable, an **OLED TV (like Sony A95K or LG C3)** may be a better investment. For **budget-conscious buyers**, a **TCL 6-Series or Samsung QN90C** could offer **similar performance at a lower cost**.

### **Recommendation**

You prioritize **gaming performance** and **Sony s image processing**.

You want a **premium 4K HDR experience** without OLED s high cost.

You prefer **Google TV s interface** and **Sony s ecosystem**.

You need a **reliable power supply** included in the purchase.

You **require Dolby Vision** for HDR content.

You **need the deepest blacks** (OLED is better).

You are on a **tight budget** (check TCL, Samsung, or LG mid-range options).

You **prioritize sound quality** (a soundbar would be a better addition).

**Final Verdict:** The **Sony KD-55A85/KD-48A9 is a well-rounded 4K TV** that delivers **great value for its price**, especially for gamers and those who value Sony s processing. If these features align with your needs, it is a **strong purchase**. Otherwise, explore **OLED or budget-friendly alternatives** for a more tailored experience.
