Question about Samsung PN42A450 Plasma TV

1 Answer

I have a Samsung PN42A450 TV and on HD channels there is pixelation on up close images that are moving. For example during the superbowl whenever a player was up close the image would degrade, get boxy, till the camera panned back.

I have a 47 inch Philips HD TV. I switched to FioS and for some reason, some channels come in very choppy or pixelated. It is not consistent but by analog TNT is fine but my HD TNT is pixelated. But my...


Long story short, it is not your fault. Your provider will blame you, TNT, will blame your provider, and both are wrong.

The most likely cause is HD TNT is not a "real" HD channel. It is probably an SD recording TNT is upscaling from SD to HD. This can occasional create a dirty HD signal being broadcasted. Some TVs have trouble decoding this signal and end up with pixelated images because the image has been pre-stretched to fix the format.

Temporary solution would be to change the resolution of you TV for just the TNT channel. Some TV will let you select a preferred mode for a channel. If you can do this, set it to 720p instead of 1080p or try 1080i for TNT to see if this improves the image.

Also make sure that only one tuner is altering the images you are receiving if you have a FIOS box. If it is processing the image image in any way (color correct, resolution, etc.) turn those features off and let the TV do it.

Vizio pixelation in hd nt all channels


Usually a TV that pixelates only on some channels is a problem with the signal levels coming into the TV or the cable box. If you are using a cable box then definatley the signal is the issue..

Can I see the difference


Visually, there is very little difference to the eye of the average consumer between 720p and 1080. However, 720p can deliver a slightly smoother-looking image, due to the fact that lines and pixels are displayed in a consecutive pattern, rather than in an alternate pattern.your tv is display format is 720p and blu ray is 1080p. what happen is it will be scaled into 720p. old tv set format is 480p 720p represents 1,280 pixels displayed across the screen horizontally and 720 pixels down the screen vertically. This arrangement yields 720 horizontal lines on the screen, which are, in turn, displayed progressively, or each line displayed following another. 1080p, on the other hand, represents 1,080 horizontal lines displayed sequentially. This means all lines are displayed during the same pass. 1080p is the highest quality HD display format. 480p represents 720 pixels displayed across the screen horizontally and 480 pixels down the screen vertically. This arrangement yields 480 horizontal lines on the screen, which are, in turn, displayed progressively, or each line displayed following another.

Coloured Pixels in or around black areas when watching TV


This is know as a diffusion issue. Most times this can be corrected with some minor alignment on the pots on the YSUS pwb. Sometimes the YSUS pwb has failed and will need to be replaced.
