How to Get the Best Picture Quality From Your 4K TV
A new television does not always deliver its best picture straight out of the box. These five practical adjustments cover HDMI cables and ports, gaming features, picture presets, and connected devices, helping you enjoy sharper, smoother, more natural-looking movies, sports, and games.
Five Easy Fixes for Better TV Picture Quality
1. Choose a Certified Ultra High Speed HDMI Cable
A reliable HDMI connection is the first step toward getting the picture quality your television and source devices support. If you use a PlayStation 5, Xbox Series X, or gaming PC at 4K and 120Hz, choose a certified Ultra High Speed HDMI cable rated for up to 48 Gbps. The HDMI 2.1 feature set can include 4K at 120Hz, variable refresh rate (VRR), and enhanced audio return channel (eARC), but the actual features depend on your equipment. An older 18 Gbps cable may still work perfectly for 4K at 60Hz, so there is no need to replace every cable automatically.A cable that cannot reliably carry the selected signal may cause brief black screens, sparkles, intermittent dropouts, or a lower negotiated refresh rate. A more expensive cable does not inherently improve colors when a digital connection is already working correctly. Instead, the goal is a stable connection at your chosen resolution, refresh rate, and HDR format.
Look for the official Ultra High Speed HDMI Certification label and verify its QR code using the HDMI certification verification process. The presenter recommends a braided, metal-housed cable described in the video as Silkland and reports testing it with a PS5, a soundbar, and a gaming PC. Those are the presenter's observations rather than independent product certification results.
2. Connect Devices to the Right HDMI Ports
Not every HDMI input on a television offers the same capabilities. Some models reserve 4K at 120Hz, VRR, or ALLM for only one or two inputs. Check the labels on the TV or its user manual before connecting a console. Look for markings such as 4K 120Hz, 144Hz, or HDMI 2.1.
In the video, the presenter identifies HDMI inputs 3 and 4 as the gaming-capable inputs on his Hisense U6-series Pro television, while HDMI 1 is labeled eARC. Port assignments vary by model and region, so confirm the layout for your own television.
If you use a compatible soundbar, connect it to the TV's eARC port to access supported higher-bandwidth audio formats. Dolby Atmos availability also depends on the television, soundbar, app, source, and audio settings.
3. Enable Gaming Features and Enhanced HDMI Format
For compatible gaming equipment, enable VRR to help reduce tearing and uneven motion when frame rates fluctuate. ALLM (Auto Low Latency Mode) lets supported devices request the television's low-latency gaming mode. Some TVs also support AMD FreeSync Premium Pro, which may improve the experience with compatible hardware.
Check for the enhanced HDMI signal setting on the specific input used by your console. Menu terminology varies by brand and model:
| TV brand | Common setting name |
|---|---|
| Samsung | Input Signal Plus or HDMI UHD Color |
| LG | HDMI Deep Color or HDMI Ultra HD Deep Color |
| Sony | HDMI Signal Format: Enhanced format |
Enable only the features your TV and source device support. A device that does not support 120Hz or VRR will not gain those capabilities simply by changing a menu setting.
4. Adjust Picture Modes, Color, Motion, and Sharpness
TVs often ship with Standard or Vivid picture presets that look striking on a showroom floor but can appear overly blue, sharp, or processed at home. For films and television programs, try Filmmaker Mode, Movie, Cinema, or Theater mode. These are often a better starting point for natural color and film-like motion. For games, choose Game Mode to reduce input latency.
- Eco mode and ambient light sensor: Disable them while evaluating the image if they make the picture too dim or inconsistent. You can turn them back on if you prefer automatic brightness or energy savings.
- Color temperature: Try Warm for a more natural white balance than the cool, blue-leaning appearance of many vivid presets.
- Motion smoothing: Turn it off for movies if you dislike the artificial soap-opera effect. For sports, modest judder or blur reduction may help; try low settings and compare.
- Motion clearness: Consider leaving black-frame insertion off if it causes noticeable flicker or reduced brightness.
- Sharpness: Start at the neutral setting, which may be zero on some models, and avoid artificial edge enhancement.
- Noise reduction: Generally disable it for clean 4K sources, although lower-quality broadcasts can sometimes benefit from a small amount.
Adjust brightness in small increments for your room rather than copying an exact number from another TV. Some televisions store separate picture settings for SDR, HDR10, Dolby Vision, and individual inputs. Check each mode while the relevant type of content is playing, and use Apply to All Inputs only when appropriate.
5. Match the Output Settings on PS5, Xbox, Apple TV, and Roku
Even a correctly configured television may not display the expected result if the connected device uses the wrong output settings. Review the device settings after confirming that the HDMI cable and input support the intended signal.
| Device | Recommended checks |
|---|---|
| PlayStation 5 | Under Screen and Video, use Automatic resolution, enable 120Hz Output and VRR when supported, enable ALLM if available, and complete Adjust HDR. |
| Xbox Series X/S | Under TV & display options, select 4K UHD and 120Hz if supported, then review VRR and auto low-latency options. |
| Apple TV 4K | Under Video and Audio, enable Match Dynamic Range and Match Frame Rate to preserve content's original presentation where supported. |
| Roku | If the model offers Auto-adjust display refresh rate, enable it to match supported content frame rates. |
Menus and available features differ by device generation and firmware version. If a setting is missing, check compatibility rather than assuming the hardware is malfunctioning.
Quick TV Picture Settings Checklist
- Confirm that your HDMI cable supports the signal you want to send.
- Use the correct HDMI port for high-refresh-rate gaming or eARC audio.
- Enable VRR, ALLM, and enhanced input format where supported.
- Choose a natural picture preset, then review motion, sharpness, and color temperature.
- Match video output settings on each connected device.
These adjustments are a useful starting point, not a universal calibration. Your best settings depend on the specific TV, the source material, and the lighting in your room. Watch the full demonstration for the presenter’s hands-on tests and on-screen menus.
