HP 47 inch MediaSmart 1080p LCD HDTV "Out of the box" digital media platform. Enjoy videos, pictures and music from home network + digital media delivered over your broadband Internet connection + 3 x HDMI

Toshiba’s 19LV505 (black) and 19LV506 (white) are 19 inch LCD HDTV/DVD combo units which can act as a compact, space saving entertainment center. DVDs are side slot loaded and the stereo speakers are bottom mounted. Toshiba have included ATSC/NTSC/QAM digital tuning for tuning of standard cable channels as well as off-air digital broadcasts, in addition to digital “cable-in-the clear” broadcasts.

As these combo LCDs could likely be used as a monitor Toshiba have given them a high WSXGA+ (Wide Super Extended Graphics Array) or 1680 x 1050 pixel resolution. The contrast ration is 800:1 which short of the exceptionally high numbers some LCDs have been getting lately. Gamers will appreciate the sharper images the fast 5ms response time will deliver. The viewing angle range for the display is not a market beater but, an adequate 160/160 H/V. For convenience, given the locations it may be situated, there is a digital clock included.

For convenient viewing alignment adjustment the screen sits on a swivel pedestal stand.

Movies for the cinema shot on 35mm or 70mm film capture 24 individual images (frames) per second which are projected at 48 frames per second to reduce flicker. To achieve 48 frames per second each frame is projected twice.

Television broadcast systems are field based. For example, NTSC (National Television Standards Committee) Video is interlaced with each frame being constructed from two consecutive fields of video containing 50% of the 480 horizontal scan lines containing picture information. NTSC video displays at 29.97 frames or 59.94 fields per second.
