Yeah after tested some Sigma 8655 and 8643 based player, I can feel the image is much more sharper than the realtek...but one thing I sit quite close to the 42" TV la...
Finally had the chance to test a Realtek based media player.
Things to note, I found that the media player clipped both black and white. On this particular media player, there was no choice to change colour space, so no way to see if it can be fixed. There was no colour decoding error that was the positive part (but this is if u do not touch the internal settings). Unfortunately, there is some sharpening out of the box, even if u turn the sharpness on the display all the way down.
Because of the clipping the peak whites cannot hit as high as the display would allow. Another negative point, was that the image was shifted by about 2 pixels bottom and left. I did not know if there was a hidden feature to shift the image. So, if ur display does not have a way to shift, u will lose some info
There are differences between the Sigma and the Realtek chipset. Until I see the new RTK chip, I cannot conclude if these bugs have been fixed.
