I Need Advice.Am Buying Mom An HDTV.Samsung TX-R3079WH

:confused: There's a new type of tv that just came out from Samsung and it was in the CES Convention back in January in Las Vegas,Nevada.
It just started to be sold at retail stores.
It's Samsung's model Number TX-R3079WH
Samsung's 30" Wide SlimFit HDTV With Built-In HDTV Tuner.
When I read reviews about it ..it said it has a Maximum of 800 Lines of Horizontal Resolution. IS That A Bad Thing????
Would I still get a great HDTV picture on this? Does ANyone Here Know?

That's 800 lines horizontal, per picture height... for a total of about 1400 pixels across. Not bad for an inexpensive TV.

"Lines of resolution" for video include both the black lines and the white spaces between them in a test pattern but not the gaps if any between scan lines or between phosphor dots/stripes
That's 800 pixels -maybe 1050 - not HDTVfor digital video the number of lines of horizontal resolution is smaller than the stated number of pixels across. This is because the scan lines or dot positions can straddle subject detail so as to reproduce nothing. Experts disagree on the ratio of lines of resolution to scan lines or pixel positions, some say as little as 70%.see: http://members.aol.com/ajaynejr/vidres.htm

:confused: the customer service person on the phone said the tv picturewas 1280X1200 or something.
Yet it has 800 horizontal lines of resolution?
I'm totally confused.
I appreciated the information you linked me to about what pixels mean and other things mean.
Will this tv give me a sharp picture?

Those high deflection angle (short) CRTs have convergence problems - try a dot pattern from a DVD to see if the convergence is acceptable. The Invar mask is supposed to be more bulletproof (heat resistant)but also is harder to manufacture so has more ragged holes compared to "regular " masks --so that is a minus for sharpness - the native resolution of NTSC (analog video) is considered to be between 400 and 640 pixels -I'm assuming that is based on 440 lines of horizontal resolution obtainable with modern comb filters. So it looks like this set is around twice as sharp in horizontal resolution as a good analog set. - If you have a good magnifier and a millimeter rule why not measure the stripes (red to red) on your Sony (I think you will find them about .9mm apart-11 per cm) - Then go to the store and measure the distance between the red dots or stripes on the Samsung -that should tell you the relative size of the pixels. multiply by the width of the tube - about 750mm to get the horizontal pixel count. --I have been trying to download the PDF User manual for the set but so far my pdf reader wont open it.- The way horizontal lines of resolution should be expressed is mentioned in that link but is often exaggerated by about 1/3 - so this tube could display more than 800 black and white vertical lines horizontally (400 black and 400 white) - if the conservative method is used - or maybe less - I notice the specs say 800 lines MAX -The horizontal resolution spec is for luminance (Black and White) - color transmitted is half that or less- - for $999 -- with a HDTV tuner and HDMI input in a small room??? - mom's eyesight like mine isnt getting any better - do it sooner rather than later -

But do you think this tv will have a sharp picture in HDTV?

Not as good as your Sony - Mom deserves better :thumbsup:

Maicaw,
The Sony and the Samsung Both have the same HD resolution though-1080i.
Why aren't they both just as good as each other? You wrote that my mom deserves the Sony.
This new Samsung is the first of it's kind ..it's the slim fit model...less of a back to it..instead of 24 1/2 inch back..it has 16 1/2.

Total horizontal res would be the '800 lines', but that is 'per vertical height'... you've got to multiply the 800 x 16/9 for total pixels... about 1400+.

You can also calc the horizontal pixels by dividing the screen width in mm by the dot pitch in mm. This number may be less than the on above based on the response of the electronics.

There is a good article in the May Scientific American about the new slim CRTs & their issues... next gen may scan vertically instead of horizontally.

High Definition is the definition of life.
There was a difference in the HD sharpness of the Sony 34XS955 that I use to own and later on I owned a Sony KV-34HS420 which does'nt have as good a picture in HD. My question to YOU is"if all these HDTV'S are in 1080i and all the SAME as you said...then why would a Sony be better than a Sumsung HDTV? Example: I want a 30 inch tube HDTV for my mom...are you saying that the Sony's picture will be better than the 30 inch Samsung for the same price?
