Can we re-use the scaler's 8bit palette to use as LUT?

Sorgelig wrote:In many cases "professional monitor" means some specific feature and completely disregards many other features. I've bough Lilliput monitor which is also called "professional" It has many buttons and rockers on face plate, it comes with sunshade and battery options, It has many digital and analog inputs. So it pretends to be a professional but:
- glossy screen - only this option should remove this monitor from professional category.
- it doesn't lock to input frame rate. So it's locked internally to 60Hz regardless input frequency.
- dark levels are quite rubbish regardless the settings.
Otherwise it's professional
