The default picture settings on most TV’s and projectors today are adjusted for best appearance when watching satellite TV. Unfortunately, these settings decreasing the quality when showing a computer screen. So to get the best image, try some of the mentioned configurations.
The resolution shown on the TV is the resolution of your computer screen scaled to your TV screen. This means that if your computer has a 720p monitor, the image streamed to your TV will also be 720p even though the TV is 1080p.
Many TVs and Projectors still use a setting called "Overscan" for standardizing a picture send from satellite or terrestrial TV, and this may be enabled by default.
Symptom: The picture edges seem to continue past the screen's edges.
To Correct Overscanning:
- Start a stream
- Open your TV's screen settings
- Look for "Screen Size" or "screen Adjustments" or "Aspect Ratio"
- Cycle through the various options until the image fits the screen correctly. Usually, the correct option is "Native", "Full" or "Unscaled.
If the TV has a PC mode this often both disables Overscan and adjust the image settings for the optimal when receiving a digital signal from a PC. On top of that, it also disables many image processing that will lower the latency when streaming.
To get the best image settings, start streaming to the screen and open a spreadsheet, since this includes different gray scales in the rows/columns and the menu bar that can be used as guidelines for the adjustments, then follow these steps:
- Find the best looking standard mode (Can be named Natural)
- Reduce contrast until all the lines in the spreadsheet are visible (Often around 70-80% of max value)
- Reduce sharpen until the text looks good and is easy to read (Often 0-20% of maximum)
A setting called “Black levels” in advanced settings can be useful for getting the light gray tones look good.
Disabling 100 Hz and other image processing settings will remove latency caused by the TV. This will make it feel more responsive. The downside will be that playing can look less fluent because the TV doesn't process extra frames.
