Sharp LC-40LE700UN Comparison

The Toshiba outperformed the Sharp LC-40LE700UN in most tests, and it’s cheaper than the Sharp (depending on the retailed). With those facts in hand, the Toshiba seems like the stronger contender. For it’s part, the Sharp had internet streaming content and photo/video/music playback. Of course, the streaming content on this particular Sharp is terrible.

The Toshiba 46XV648U had a much lower black level as well as a significantly brighter peak white. As a result, the contrast ratio is nearly twice as wide as the Sharp LC-40LE700UN.

The color performance of both the Toshiba and the Sharp was very good, and the scores are close enough to consider being tied. You won’t be disappointed with either.

The motion performance of the Toshiba 46XV648U was distinctly better than the Sharp LC-40LE700UN, thanks in large part to the Toshiba ClearFrame feature, which helped maintain fine detail in objects in motion. Sure, there were still some instances of artifacting, but we really liked what we saw in the Toshiba.

The viewing angle is one of the few areas of core performance where the Sharp outperformed the Toshiba. The Sharp had a viewing angle of roughly 55 degrees, while the Toshiba clocked in at 48 degrees.

The Sharp undoubtedly has a better array of ports than the Toshiba, including an additional HDMI, an ethernet port for streaming content, and an infrequently used but nevertheless present RS-232C port.

With its reasonably good performance in many categories and more internet features than you can shake an e-stick at, that question might be hard to answer if it weren't for this review.
