Can anyone comment on their sets -- especially viewing them in home lighting situations?
This is going to be an issue that will vary from set to set. My particular 42LB5D doesn't suffer from this, but that's no guarantee that if you buy one you won't have these issues. Based on what people are saying about this TV, your odds should be pretty good that you'll get uniform set.
2. Audio sync issues - some sets seem to not be able to sync up the audio and video coming through the HDMI cable very well. From what I have seen, it is usually the audio that is ahead of the video processing. I hear HDMI 1.3 has some sort of lip sync feature but I imagine it requires HDMI 1.3 on both ends to work. Anyone have comments on this issue with the LB5D and know for sure whether the LB5D series definitely has 1.3?
Like the other poster in this thread, I've not noticed this issue with my PS3 hooked up via HDMI, both in games and while watching Blu-ray movies.
3. USB connection - I would like to do slideshows of my 8 mp .jpg pictures through the USB connection. Anyone tried this and can comment on how fast the LB5D is able to switch photos and draw the images on the screen (some TVs take forever)?
I put a few slightly lower resolution images on a spare USB thumb drive I had and plugged it into the TV. The definition of "forever" is certainly subjective, but the pictures didn't take terribly long to load. Your best bet is to experiment with it. If you brought in a thumb drive with some pictures on it, the store should let you try it out.
4. Off center viewing - they all advertise 170+ degrees but some wash out badly at as little as 45% off center. Not so good if some of your prime seating is off center. The LB5D looked pretty good in the store but the lighting makes it hard to judge so I would like to hear from some folks who have checked it out in their homes - especially in the dark with minimal lighting.
By virtue of the way my living room is laid out, I have to sit at an angle from the TV, and it looks just about every bit as good as staring at it straight on.
5. Pixel issues - stuck, hot and dead pixel are defects to me no matter what the manufacturers say about being a normal occurance. I occasionally watch from less than 8 feet and can see a hot pixel on a 1080 set in a dark sceen at that distance which I find distracting. Can those of you who have purchased one of these comment on whether yours was pixel defect free?
Not a single dead or stuck pixel on my set.
6. Overscan - I have seen some comments that indicate there is no 1:1 pixel mapping on this series which I find kind of hard to believe. The spec sheet says there are 6 aspect ratio adjustments. Isn't one of them a "full" mode with no overscan? I am primarily interested in the HDMI connections but would like to hear about folks' observations through component and direct RF as well.
I don't think there is one on this set, but I'm not having much of an issue with overscan on my set. Maybe 1% at the absolute maximum. I'll have to dig around and see what I can find about a full mode.
