Yes this is dumb, since 1920x1080 is a native res and shouldnt be scaled at all, but for some reason, one out of three aspect modes in OSD, results as "true direct" and two others are buffered.RealNC wrote:So let me get this straight: when using 1080p, which should just always use the same path through the scaler since it's the native res, doesn't use the same path and is tied to the scaling option selected in the OSD?
That's just not right. Somebody screwed up at LG :-/
I dont see a reason why that was made, I was supposing that Original mode may be somehow related to advertised on LG's site "Dynamic action sync" and e.g. enables that hidden feature due to dedication of Original mode to CS 4:3 resolution gamers.
But, DAS shouldnt work along with the strobing (again, according to LG's site), but in Original mode measured input lag decreases regardless if strobing is on/off. So I think its just an "true direct" mode without any buffering, thats also why it shows yourself more stable in raised VT operation, then buffered modes.
It also may be that Original is just a wrong name and it was supposed to be named more straight.
Also, its clear that LG uses an Mstar scaler just like many others, its an Mstar having different paths for 1080p which are tied to some OSD-controllable options, not LG. E.g. Benq implement that direct path with their "instant mode", when LG hides their advertised DAS mode and ties direct path to another OSD option. There'll be not such a case, if Mstar scalers and firmwares didnt have different paths for a native res signals. But sure, LG's implementation is unclear for users and reviewers.
