How to adjust image settings on WebOS and Tizen TVs – A complete guide
Modern LG and Samsung smart TVs offer an impressive range of picture options that often go unused. Anyone who wants to take their streaming enjoyment to the next level should know how to use the available settings deliberately. In this article, we show you how to adjust image settings on WebOS (LG) and Tizen (Samsung) TVs – step by step, clearly and with a practical focus.
Why the right picture settings matter so much
Many users open their new streaming app, start their favourite channel and wonder why the picture looks flat, overly bright or unnatural. The reason: factory settings on smart TVs are optimised for the showroom – not for your living room. Only those who understand how to adjust image settings correctly will unlock their TV’s full potential.
This is especially true when streaming through services such as Zenova TV, where it pays to fine-tune the picture parameters carefully. Incorrectly configured brightness or exaggerated sharpness can noticeably degrade the experience.
Optimising picture settings on LG WebOS
Step 1: Choose the right picture mode
LG WebOS offers several predefined picture modes: Cinema, Standard, Sports, Expert (Bright Room) and Expert (Dark Room). For everyday streaming, we recommend Cinema or Expert (Dark Room). These modes deliver lifelike colours and a balanced contrast range.
How to navigate: Settings → All Settings → Picture → Picture Mode
Step 2: Fine-tune OLED brightness and contrast
If you own an LG OLED device, you have access to OLED brightness. Set this value to 80–90 for dark rooms and 100 for bright environments. Contrast should be around 85. This gives you deep blacks without losing detail in dark scenes.
Step 3: Adjust colour temperature and white balance
Colour temperature determines how warm or cool the picture looks. For streaming content, we recommend Warm2 – it comes closest to the standard cinema white balance (D65) and is documented in ITU-R BT.709, the official colour standard for HDTV content.
Step 4: Turn off TruMotion
The so-called soap opera effect is caused by LG’s TruMotion function. This motion smoothing is intended for sports events but significantly distorts film and series content. Set TruMotion to Off or Film Recording to preserve a natural motion flow.
Optimising picture settings on Samsung Tizen
Activate Filmmaker Mode
With Filmmaker Mode, Samsung has introduced a particularly practical function. This mode automatically switches off all picture-distorting post-processing and delivers the picture as the director intended. Anyone who wants to know how to adjust image settings on Samsung Tizen should activate Filmmaker Mode as their first step.
Path: Settings → General → Picture → Picture Mode → Filmmaker Mode
Adjust brightness, contrast and gamma
On Samsung devices too, factory values are excessively bright and saturated. Recommended baseline values for a typical living room:
- Brightness: 45–55
- Contrast: 80–90
- Sharpness: 0–10 (less is more)
- Colour: 45–50
- Tint (Green/Red): Keep neutral
Disable Auto Motion Plus
Just like LG’s TruMotion, Samsung’s Auto Motion Plus creates the unwanted soap-opera effect. Turn this feature off under Settings → Picture → Expert Settings → Auto Motion Plus to display filmic content true to the original.
HDR and Dolby Vision settings
If your content is in HDR10 or HDR10+, Samsung Tizen activates HDR mode automatically. Important: disable manual brightness sliders in HDR mode, as the system manages the tone curve itself. That is the simplest and most effective way to adjust image settings for HDR content.
Shared tips for both platforms
Whether you use WebOS or Tizen, universal principles apply when it comes to how to adjust image settings reliably and permanently:
- Always calibrate under your usual room lighting.
- Use test patterns (e.g. THX certification clips or calibration discs) for precise tuning.
- Save your settings separately per input source – HDMI 1 and HDMI 2 may need different values.
- Check your settings after firmware updates, as updates sometimes reset values.
With the right settings, your streaming experience with Zenova TV becomes considerably richer – from vivid colours to precise blacks.
Frequently asked questions (FAQs)
1. Do I need a professional to adjust image settings?
No. With our guide you can make the adjustments yourself. Professional ISF calibrations are possible for absolute perfection, but for home use manual adjustments are entirely sufficient.
2. How often should I check my picture settings?
A check is advisable after every major firmware update and seasonally, when the natural light conditions in your room change.
3. Does maximum brightness damage the TV set?
On OLED TVs, sustained maximum brightness can affect pixel lifespan. Keep brightness at a sensible level, especially with static on-screen content.
4. Why does the picture look darker after I adjust it?
That is a good sign. Factory settings exaggerate brightness and contrast for showroom conditions. The calibrated picture looks more subdued at first, but it is easier on the eyes and closer to the source.
5. Do these settings also apply to IPTV streaming via Zenova TV?
Yes, absolutely. Once you know how to adjust image settings on your Smart TV, every type of content benefits – including live TV, VOD and all channels in the Zenova TV line-up.
