motion blur or ghosting on the picture. Can a low quality HDMI cable be the cause of this?

No, it is because of the TV. Low-cost brands such as Sanyo generally have a low response rate. Even older high-quality LCD sets have this problem, such as the Samsung LN-T3253H.

Fuzzy lines that are not all the time mean interference. Search Amazon for "ferrite bead" and get one of the ferrite clips. I have them on all of my HDMI cords. Usually the reason to buy more expensive HDMI cords is because they are more insulated to prevent interference, but it is cheaper to get a clip on ferrite bead. If you only have one, clip it on the side with the monitor/tv. You can clip it on both sides of the cord if you have multiple. I just want to note that if you have fuzzy letters or image, then there might be a resolution conflict. For example, you are outputting 1080p when your screen only supports 720p. Another common problem that causes blurryness is overscan in screens which cuts off the edges of the image and then resizes the image to fit full screen. They do this because cable television usually comes in with weird white lines on the edges and overscan removes that. You can sometimes disable this in the screen's settings. Hopefully this solves your problem!

Could be your receiver also. Check settings as you can toggle delay to smooth out picture as well as sync with audio. Previous plasmas from Panasonic suffered from pixelation (especially on dark colors) but I've been very happy so far with this model.

I have had no problems with picture quality. I would suggest rechecking all of the connections, but I am sure you did that already. Sorry; I am the original electronic idiot!

Make sure your mini display port is enabled. If you are using HDMI it causes that flicker because it's at a different frequency. If you use the mini display port it will be clear and very smooth motion that will help that eyestrain greatly.

No. Sounds like a problem with your video card or HDMI cable. First try using a "high speed" shielded HDMI cable, like the original that came with the monitor.

Have similar issue, seems the hdmi out port is to blame, changed all the cables (several times) to no avail. This started after only 6 days, bought because of a relative small number of problems, only to encounter one myself. I have yet to find a fix and not willing at this time to have it repaired will prob send back for a replacement

It's a source issue..plasmas handle fast motion better than other types of TV. Many sources are poor though. Make sure your motion smoothing is turned off too.

When I tried using the composite upconversion for the Wii, the picture looked terrible! It was very grainy and there were bars on all 4 sides. I have since bought a componet cable for the Wii and the picture quality is much better but there are still bars around the picture. When the Wii is connected directly to my 55" Sony LCD, it looks perfect. I called Sony support and they thought the receiver was defective so I exchanged it for a new DH820, and had the same results.

I made setting adjustments, updated the firmware and have since watched scenes with dark backgrounds and it seems to have gone away? Don't know why for sure but so far, so good. Thought the same. Perhaps it is a HDMI cable issue but was seeing it both on tv broadcasts as well as DVD so felt it must have been related to some sort of setting? Don't think both of my HDMI cables would have been bad! Thanks.

I have had my system for a year come the end of September. I use it for CaTV (1080P), Home Theater (1080 again), BluRay, DVD and several smart TV functions like Netflix and Amazon prime video, plus screen sharing from Android over WiFi. In other words it is getting a good workout. I do no have green dots, nor dots of any kind. What I would check first is the cabling. A lot of times, video noise (think VGA or SVGA here as an example) can be caused by cables that have become kinked or severely twisted, are picking up noise from adjacent power sources, or by a connector that may have damaged the HDMI receptacle. Even if you have to run a new cable over the floor to see if that is the problem (don't pull it into the same space as the existing cable just yet) between the video source and the TV. Before doing that, try Netflix or something that doesn't use the cables in question. If that is OK, look to your cables for the problem... I really hope that helps!

As has been mentioned, vibration and a lot of movement will cause distortion. Also extreme light or extreme darkness will cause a grainy picture. but keeping camera steady, not moving you head a lot, and average lighting should give you acceptable video.

Motion blur is a very subjective thing. Everyone seems to look at it differently. In my opinion, TV's that are built for a standard refresh rate (60hz) are generally the most consistent to how they deal with motion blur, because it's a well established standard, so everyone designs for it. If you're using a non-standard refresh rate (say 120hz), then the software has to deal with modifying the input, and you have some sort of conversion going on. I've seen TV's that look *terrible* even on simple camera pan's, because they use a non-standard refresh rate and the software deals with it poorly. On the other hand, the owner of that TV swears it looks great (maybe because he shelled out $$$ for it). The absolute best thing you can do is to see it in person. That's really the only way you can tell if it's going to work for you or not. Partially as well it depends on TV settings and input source (and settings), so this is something that can be really difficult to figure out before you pull the trigger on your purchase. Fortunately Amazon does have a good return policy, so the best thing may be to buy it, try it, and return it if you don't like it.

Try changing the resolution or the refresh rate. Maybe the cable is defective?

I'm assuming the picture lags behind the audio, which is fairly common with HDMI. Use the A/V sync feature on the receiver (it's under Audio Adjust); 40ms is usually a good starting point.

No. You might want to play with the settings. I have mine set on Vivid. I am assuming you had a good signal before. I would try regular HDMI cables. I tried 4k HDMI cable through my cable box and got a good picture but sound problems.

The picture on my set is nice and crisp. First off use only an HDMI cable. If you are using any other way to connect, you will not have the best picture. If you are using a cable box, make sure the resolution is set to 1920x1080I as many cable boxes default to a lower resolution setting. I had to adjust my setting even though it was a "high definition" box. Hope this helps.
