Sir question, I used to own a Samsung S71 before and using it with a DVI-VGA cable as a primary monitor, it gave me a resolution of 1366x768 only but when I used my DVI - HDMI cable, my resolution settings increased upto 1920x1080 (or even more) but using the max resolution will give you ghosting especially when moving the mouse cursor. Do you have any idea why did that happen and what will happen if I sticked to the 1920x1080 resolution knowing my required resolution only is 1366x768?
Before flat panel TVs became commonplace, the old concept for flat panel TVs was that a higher resolution would always be better than a lower resolution.
Now that more owners have actually seen the result, the new concept is that a higher resolution would not necessarily produce a better picture; it will depend on how the signal is handled by the components used.
The different resolution capabilities of your former TV depended on the resolutions supported by the TV's internal scaler. No support, no display. It just so happened that the TV supported higher resolutions via HDMI connection.
Now, using a 1920 x 1080 setting via HDMI, would the picture be better on a TV with a 1366 x 768 native resolution?
Not necessarily. There's just no way to determine in advance how the TV's scaler will handle the signal, considering that the TV manufacturers don't publish how their scalers are actually processing the different video input signals. It's probably a trade secret, so we might never know.
The only way to know if a higher rez signal will produce a better image would be by actually testing the input signal and eyeballing the resulting image. In your case, you already gave the 1080 signal an eyeball test and determined that the picture is actually worse with a 1080 signal because the scaler produces ghosting artifacts on small moving objects.
Why so? The panel's scaler is not doing a good job of converting the 1080 input to its native resolution. A good rule of thumb would be to feed the panel a resolution closest to its own native resolution. But this is not an absolute rule. Again, it depends on how the panel's scaler handles the input, and the only way to know which is better is by actually testing and comparing for yourself.
... what will happen if I sticked to the 1920x1080 resolution knowing my required resolution only is 1366x768?
OK lang. The panel supports a 1920 x 1080 input, so walang problema. You just get the motion artifacts, pero walang masisira.
