Adjust brightness, contrast and sharpness to create a cleaner, more balanced Roku TV picture.
Choose suitable color temperature and picture modes based on your room and viewing preferences.
Fine-tune local dimming and motion settings for better contrast and smoother moving scenes.
Buying a new Roku TV does not always mean you are getting the best possible picture from it. Out-of-the-box settings are designed to work for a wide range of viewers and rooms, but a few simple adjustments can make colors look more natural, improve contrast and make movies or sports easier to watch.
You do not need to be an expert to make these changes. Roku TVs offer several picture controls that can be adjusted directly from the settings menu.
The exact options can vary depending on the TV model, but these seven changes are a good place to start:
Picture mode is the easiest setting to change and can immediately affect how your TV looks. Roku TVs can offer modes such as Standard, Vivid, Sports, Movie and Low Power, while some models also include Roku Smart Picture.
For everyday viewing, Standard can be a good starting point. If you mostly watch movies in a darker room, the Movie mode may provide a more comfortable and natural-looking picture.
If your TV looks washed out, the brightness setting may be too high. On the other hand, setting it too low can make details disappear in dark scenes.
Try adjusting the brightness while watching a scene with shadows and darker areas. The goal is to keep those details visible without making black areas look grey.

Contrast affects how bright the lighter parts of the picture appear. Increasing it slightly can make the image look more lively, but pushing it too far can cause bright areas to lose detail.
Watch scenes containing white shirts, clouds or bright lights while making small adjustments. If those areas start looking completely white without visible detail, lower the contrast.
More sharpness does not always mean a sharper picture. In fact, setting it too high can make edges look unnatural and create visible outlines around objects.
If faces, buildings or text appear overly processed, try lowering the Sharpness setting. Compare the result with the original setting to see which looks more natural.
Color temperature can have a noticeable effect on the overall appearance of your TV. A cooler setting can make whites appear more bluish, while a warmer setting can give the picture a softer, more natural tone.
For films and TV shows, the Warm setting can be worth trying. However, personal preference matters here, so spend a few minutes comparing the available options.
If your Roku TV supports local dimming, this setting can improve contrast by adjusting different areas of the backlight separately.
You may find options such as Off, Low, Medium and High. Start with a lower setting and increase it if you want deeper blacks and stronger contrast. The result can vary considerably between TV models.
Motion smoothing is designed to make fast-moving scenes appear smoother. It can be useful for sports, but some viewers may find that it makes films look unnatural.
If you notice the so-called soap-opera effect while watching movies, try reducing Action Smoothing or turning it off. For sports and other fast-moving content, a low level of motion processing may be more useful.

Getting a better picture from your Roku TV does not require hours of calibration. Start with the picture mode, then make small changes to brightness, contrast, sharpness and color temperature. If your TV supports features such as local dimming and motion controls, adjust those according to what you watch most.
There is no single combination that will look perfect on every Roku TV. Your room, TV model and personal preference all play a role. The best approach is to make one change at a time and compare the picture before deciding whether to keep it.
How do I improve picture quality on my Roku TV?
Start by selecting the appropriate picture mode, then adjust brightness, contrast, sharpness and color temperature. Fine-tune motion and local dimming if available.
Which picture mode should I use on Roku TV?
Standard works well for everyday viewing, while Movie can suit darker rooms. Sports may help with fast-moving content, depending on your television model.
Should I turn down sharpness on my Roku TV?
Yes, if the picture looks artificial or objects have visible outlines. Lowering sharpness can create a more natural image while preserving important details.
What does local dimming do on Roku TV?
Local dimming adjusts different backlight areas independently, helping compatible Roku TVs produce deeper blacks and stronger contrast, particularly when watching content in darker rooms.
Should I turn off motion smoothing for movies?
If motion smoothing makes films look unnatural or creates a soap-opera effect, reduce or disable it. Lower motion processing can provide a more cinematic appearance.
