Recognise what the menu describes
NVIDIA’s Control Panel documentation distinguishes Full and Limited RGB output ranges. Intel’s explanation gives the familiar nominal 8-bit values: 0–255 for full range and 16–235 for limited black-to-white. These are signal interpretation conventions. They are not screen resolution, bit depth or a direct measure of a television’s brightness, and a menu titled dynamic range in this context is not automatically an HDR on/off control.
Match both ends of the connection
The source and receiving display need a compatible interpretation. Selecting one range at the computer while the display expects another can affect how picture levels are shown. Check the exact television or monitor documentation for its input setting rather than assuming every brand calls it Full, Low or Normal. The safest answer is a matching documented pair, not whichever option sounds more impressive.
Compare without stacking picture changes
Record the original output and display settings, then use a suitable lawful test image or familiar scene. Change one relevant control at a time. If you also alter brightness, contrast and HDR mode, it becomes difficult to identify which change caused the result. Avoid diagnosing a range mismatch from one deliberately dark film scene; the source itself may contain artistic choices or other picture characteristics.
Keep device scope explicit
The cited NVIDIA controls concern a computer graphics-driver interface. A streaming box and a television may expose different options or manage the choice automatically. Do not copy a computer menu path into an unrelated device guide. If a specific input looks wrong, report the source device, connection route and both range settings where available. This establishes a focused display question without implying a defect in every stream.
Questions, answered
Should I always choose Full RGB?
Choose a range that the display correctly accepts and interprets. The label alone does not establish a universal improvement; check both ends of the connection.
