A:AnswerHello there, Bob. We understand your inquiry about whether your LG 55" Class 85 Series QNED 4K UHD Smart webOS TV (Model 55QNED85TUA) can run 120 Hz at 4K when connected to gaming systems. Below is detailed information on how to enable and troubleshoot 4K @ 120 Hz gaming on this TV, along with a helpful step you can take to ensure everything is configured correctly.
1. HDMI 2.1 Inputs for 4K @ 120 Hz
Your 55QNED85TUA comes equipped with four HDMI inputs (all HDMI 2.1), which are capable of handling 4K @ 120 Hz signals from the latest gaming consoles (such as PlayStation 5 and Xbox Series X). By design, HDMI 2.1 supports a peak bandwidth up to 48 Gbps—enough to carry uncompressed 4K video at 120 Hz with HDR. To make use of 4K @ 120 Hz, you must:
Plug your gaming console into one of the HDMI 2.1 ports (HDMI 1, 2, 3, or 4 all support HDMI 2.1 signal bandwidth).
Use a certified Ultra High Speed HDMI cable (included with most consoles, or sold separately) to ensure the full HDMI 2.1 bandwidth is available for 4K @ 120 Hz + HDR.
2. Enabling “HDMI Ultra HD Deep Color” (Troubleshooting Step)
Even though the physical ports are HDMI 2.1, the TV’s software requires you to turn on “HDMI Ultra HD Deep Color” for the port you’re using. This setting allows the TV to open the full HDMI 2.1 pipeline; otherwise, it defaults to a lower data rate that only supports 4K @ 60 Hz. Here’s how to enable it:
On your TV remote, press Settings (the gear icon).
Navigate to All Settings → Connection → HDMI Input Settings → HDMI ULTRA HD Deep Color.
Find the HDMI port number (e.g., HDMI 1, HDMI 2, HDMI 3, or HDMI 4) where your console is connected, and switch “HDMI ULTRA HD Deep Color” to On.
Power-cycle both your TV and gaming console: turn them off, unplug for 30 seconds, then plug back in and power them on (TV first, then console). This ensures the console negotiates a new “handshake” with the TV at 4K @ 120 Hz.
If your console’s video output is set to 4K @ 120 Hz and its HDMI cable is firmly plugged into an HDMI 2.1 port with “HDMI Ultra HD Deep Color” enabled, your TV should automatically detect the higher refresh rate. You can verify this by:
Going to the TV’s Settings → All Settings → Sound & Picture → Picture Mode → Game Optimizer. Within Game Optimizer, look for “4K @ 120 Hz” to confirm the resolution and refresh rate currently being received.
On your console (for example, on an Xbox Series X), go to Settings → General → TV & Display Options and confirm that “4K UHD” and “120 Hz” are active under “Refresh Rate.”
3. Using Game Optimizer & Game Dashboard
To ensure the smoothest experience, place the TV in Game Optimizer mode once 4K @ 120 Hz is enabled. This automatically adjusts input lag, disables unnecessary post-processing, and optimizes colors for gaming. Access it via:
Settings → All Settings → Sound & Picture → Picture Mode and select Game Optimizer.
Inside Game Optimizer, you’ll see an on-screen “Game Dashboard” overlay. It displays real-time information—such as resolution, refresh rate, VRR (Variable Refresh Rate) status, and HDR mode—so you can confirm that 4K @ 120 Hz is active.
4. Confirming VRR / AMD FreeSync Compatibility
Your 55QNED85TUA also supports AMD FreeSync (VRR) to prevent screen tearing at higher refresh rates. In Settings → All Settings → Sound & Picture → Picture Mode, after selecting Game Optimizer, scroll down to Game Adjust and turn on AMD FreeSync Premium. If your console or PC supports VRR over HDMI 2.1, this will further enhance responsiveness and visual smoothness when running games at 4K @ 120 Hz.
5. Potential Issues & Additional Tips
If you still see “4K @ 60 Hz” instead of 4K @ 120 Hz:
Double-check that your console is set to output at 4K @ 120 Hz (verify in the console’s video settings).
Confirm the HDMI cable is firmly seated in the TV’s HDMI 2.1 port (removing and re-inserting can help the handshake).
Make sure the TV’s firmware is up to date: Settings → All Settings → General → About This TV → Check for Updates. Updating can fix HDMI handshake bugs.
If you experience screen flicker or loss of video when switching to 4K @ 120 Hz, try toggling “HDMI Ultra HD Deep Color” Off and then back On, and repeat the power-cycle step above.
6. Summary
Yes, the 55QNED85TUA supports native 4K @ 120 Hz for gaming systems via any of its four HDMI 2.1 inputs—provided you enable HDMI Ultra HD Deep Color on the chosen port and use a certified Ultra High Speed HDMI cable.
Use Game Optimizer mode to view real-time confirmation of 4K @ 120 Hz operation, and enable AMD FreeSync Premium if you want VRR support.

A:AnswerHello there. Thank you for sharing your inquiry with us. We understand your situation regarding which model might be better suited for your needs between the 55QNED85TUA (Class 85) and the 55QNED80TUC (Class 80).
The 55QNED85TUA offers a higher native refresh rate of 120Hz compared to the 60Hz of the 55QNED80TUC. This means the Class 85 model delivers smoother motion handling, which is especially beneficial for fast-paced content such as sports and gaming. Additionally, the 85 model features a more advanced α8 AI Processor 4K and Dynamic Tone Mapping Pro, providing enhanced picture processing, better upscaling, and superior HDR performance. It also includes additional HDMI inputs and advanced gaming features like FreeSync™, all of which elevate the overall viewing experience.
On the other hand, the 55QNED80TUC still delivers excellent picture quality and smart features that are typical of LG’s QNED series, making it a solid option for everyday viewing if ultra-high performance isn’t your primary focus.
As a troubleshooting step, if you have the opportunity to experience both models in a showroom or through a demo, we recommend comparing features such as motion smoothing, game mode, and HDR performance. This hands-on evaluation can help you determine which model aligns best with your viewing preferences.

A:AnswerHow long have you had the LG 55" Class 85 Series QNED 4K UHD Smart webOS TV (2024), Model # 55QNED85TUA and have you always had this issue or is this something recent?
A service technician will need to inspect and diagnose the TV to determine what is causing the "tiny horizontal dark lines across the screen"...^Ivan.
A:AnswerHi, there. Thanks for reaching out with your question about the LG TV (55QNED85TUA) model. The absence of a headphone jack, external speaker ports, and composite in/output on this model is a result of the design trend in modern TVs, which focus on more advanced and streamlined connectivity options. Many newer models, including the 55QNED85TUA, are moving towards wireless audio solutions, such as Bluetooth. This allows you to connect Bluetooth headphones or speakers, offering a cleaner design without the need for a physical headphone port. For external sound systems, the TV likely supports HDMI ARC (Audio Return Channel) or eARC, which provides better sound quality and flexibility with soundbars or external speakers. You can also use optical audio output for high-quality audio connections to external speakers. Feel free to reach out if you have any other questions, or if you need assistance setting up audio or connectivity. You can always send us a private message on social media @LGUSSupport, and we’ll be happy to help. ^Juvy
