I have calibrated my tcp60st60 using the cnet settings and the picture looks good overall but the brightness is lacking. My main gripe is that there is a considerable difference is brightness when viewing the TV's menu compared to everything else (HDMI, netflix app, youtube, etc). Say I plug in my macbook and look at a white background. The white is a dull grey colour and it's a bit hard to read things. If I then bring up the TV menu, the change in brightness is extreme. All the menu text is a vivid white and the part of the background image that isn't covered by the menu (right side) becomes a vivid white as well. See the attached pictures for an example.
Any idea why this happens and is this the expected behaviour for this tv? I hope I can improve the picture as I can't really make use of the TV right now until the evening and my room isn't even that bright during the day!
