Samsung LN32A450 32-Inch 720p LCD HDTV
A sleek design with hidden speakers keep Samsung's Series 4 large flatpanel HDTVs one of the best 720p HD options around. Upgrades over last year's models include a 6ms response rate that's faster than many more expensive 1080p models for smooth motion even with fast-moving sports and action movies, and a higher dynamic contrast ratio of 10,000:1 (up from 8,000:1 last year) for deep blacks and crisp lines. Please note that this description applies to Series 4 models 32 inches or larger. Models 26 inches and smaller have slightly different specifications.
Samsung enhances the clarity of select LCD HDTVs by replacing the light-diffusing plastic face of traditional LCD HDTVs with a natural black panel with a clear anti-glare shield. Reduced reflection of external light creates a new dimension in image clarity, highlighting black and darkened areas, enabling vibrant, more compelling colors and a brighter, clearer picture. Black will never again appear grayish. Black details will show in vivid black even in dark scenes.The latest version of Samsung’s breakthrough super clear panel technology makes colors appear more vibrant and blacks even deeper than ever. Enhanced films reduce glare and optimize off-angle viewing.
Sony KE32TS2 32-Inch WEGA HDTV Integrated Flat Panel Plasma TV
Sony's second-generation KE-32TS2 16:9 widescreen gas-plasma TV offers elegant WEGA styling with improved performance features over its predecessor, including 38 percent higher peak brightness (though Sony has not disclosed the actual brightness rating). The set includes everything you need to get the set up and running in minutes, from an NTSC broadcast tuner to built-in stereo speakers and even a handy pedestal for tabletop positioning.
The set's native 852 x 1024 pixel resolution (vertical x horizontal) ensures detailed images, while 1,000:1 contrast ratio means you'll see deep black and vivid, dynamic images from just about any source. Use it with a DTV set-top receiver for viewing full high-definition programming (720p, 1080i scaled for 1024 display) or with your progressive-scan DVD player for seamless, flicker-free images at 480p. Onboard Pixel by Pixel I/P (interlace to progressive) conversion reconstructs interlaced (480i) film or video scenes one pixel at a time for fluid, life-like motion along with breathtaking image detail.
With a plasma screen you get vivid colors like you've never seen before, extremely wide viewing angles (wider, even, than those of most LCD screens), and easy placement due to a plasma monitor's slim profile--the KE-32TS2 is a mere 5.25 inches deep, perfect for desk or wall mounting. Brightness tends to be extremely uniform across plasma screens, which are also impervious to the picture distortion and negative color balances that afflict CRT monitors when placed near lighting or sound systems.
For 32-Inch TV, i think maybe you should be choose a LCD TV.

Contrast ratio
Even in a fully switched-off state, liquid crystals allow some light to leak through the shutters. This limits their contrast ratios, to about 1000:1 on the best modern sets. This is most noticeable in darker scenes, where the limited number of available shades of grey can lead to "posterizing" effects and bands of discrete colors that become visible in shadows. For contrast, CRTs and plasma displays offer peak contrast ratios on the order of 3000:1, and some plasma sets offer ratios as high as 20,000:1. Canon's prototype 55" SED offered a 50,000:1 contrast ratio.
