Samsung LCD Not Showing 1080p

by floyd855 / January 15, 2009 7:41 AM PST

I have a samsung 46 inch lcd tv, model number ln46a550p. I am having trouble determining if my tv is outputting 1080p.

When my hd cable is plugged in, the tv shows 1920 x 1080i @ 60hz. This is good. When I plug in my blue ray player (using an HDMI cable) the tv shows 1920 x 1080 @ 60hz. I would have expected to see 1920 x 1080p @ 60hz.

I have taken my blue ray player and the same HDMI cable onto another tv, and the other tv (the other tv is an aquos) does show 1920 x 1080p @ 60hz. So at this point, I do not believe that it is a problem with my blue ray player or my hdmi cable.

How can I confirm that I am in fact receiving 1080p when I watch a blue ray movie?

Thank you in advance.

only shows INcoming resolution
by washburn27 / January 15, 2009 8:42 AM PST

The TV only shows INcoming resolution (what you're feeding IN to the TV, otherwise known as the resolution of your SOURCE).
The TV never displays the OUTresolution. so although you're seeing 1080p (because the tv does upconvert anything you feed into it to 1080p), you will never see the real output numbers (1080p) displayed.

only time you'll ever see "1080p" DISPLAYED when you press "info" is if your SOURCE is ALREADY 1080p.

set your dvdp or bluray player to 1080p output and then check on the TV. (still it's showing what's coming IN; what you see, coming OUT of the tv is ALWYAS 1080p, so there;s no need to display that really)

p is assumed to be the default
by clicq / January 15, 2009 12:23 PM PST

The incoming signal can either be progressive (p) or interlaced (i). You only need to indicate one, so the other is assumed -- in this case, the TV indicates when you have interlaced input with an i after the resolution. Anything without the i is progressive, so it's 1080p, they just decided to leave off the p.

So basically, 1920x1080 @ 60Hz is 1080p.

Thanks guys....

Yes, indeed, the Info Button, as washburn noted, shows the incoming signal.

Clicq was right, also:

1080i on the input bar denotes 1080i.
1080 on the input bar denotes 1080p
1080p on the input bar also denotes 1080p for some units.

You guys are good. Thanks! Happy
