Sharp’s LC-57D90U LCD is a full 1080p (1920 x 1080) capable high definition LCD widescreen television with a built in HDTV tuner. Along with its other Sharp 90U series siblings, it has a titanium finish and twin detachable speakers. The television comes with a stand which can be removed for wall mounting.

The Sharp AQUOS line has been recognized by awards as setting a standard for LCD panel performance. However, a detraction with this model worth noting is that neither digital input type provided will accept 1080p signals removing the possibility of enjoying the latest high definition DVDs.

Some standout features of the LC-57D90U Sharp AQUOS are:

• Sharp’s new Four Wavelength Backlight System that adds a vivid crimson red to the traditional three-wavelength Red, Green and Blue LCD backlight. Sharp advertise that the result is a vast improvement in natural color reproduction minus any over saturation that can occur with LCD TV panels. To quote Sharp, “This added color wavelength reproduces red scale colors that were once difficult to reproduce, such as those found in the deep red of wine, or a stunning red dress…” It is a development that brings these LCDs closer to the performance of the best plasma televisions for color performance.
• Excellent viewing angles have been delivered by Sharp’s proprietary Multi-Pixel Technology. Multi-Pixel Technology divides each pixel into two sections and adds an advanced driving system for improved color reproduction at wide viewing angles. The viewing angle for the LC-57D90U is an excellent 176 degrees.
• CableCARD slot with an integrated TV Guide On Screen program guide allows viewing of digital cable programs, including premium channels, without the need for an external cable box.
• Sharp’s proprietary Advanced Super View (ASV) / Black TFT Panel with multi-pixel technology for decreased colorshift.
• Built-in ATSC, QAM and NTSC tuners for access to DTV and analog TV channels.
• Low reflection black TFT panel to reduce ambient light glare
• A suitably high contrast ratio of 1500:1
• Further improved response times with Sharp’s Enhanced Quick Shoot video circuitry delivering a very fast pixel response time of 4 ms that promises excellent picture quality in fast-moving action video. Something gamers will note.
• Enhanced black levels
• Long lamp life of 60,000 hours.
