Sharp LE830 / LE835 review

Sharp has released the LE830 / LE835 range of Edge LED based TVs as a successor to last year’s LE820 range that was the first to incorporate Sharp’s new Quattron panel technology. Last year’s LE820 model performed well but we hope to see further improvements in the new LE830 range that now comes with a matte panel instead of the glass front. LE830 also comes with Internet functionality plus 3D (called LE835 in the US) and will be available up to 70 inches later this year.US readers notice: LE830 comes without 3D in the US. LE835 is the same TV with added 3D functionality in the US. The European LE830 comes with 3D. There is no LE835 in Europe. Sharp LE830 / LE835 is available in 40, 46, 52, 60 and 70 inches called 40LE830, 46LE830, 52LE830, 60LE830 and 70LE830 in the US and EU. Some EU countries have a LE831 variant.But how good is LE830? Is it a real alternative to Samsung’s D8000 LED model? And has Sharp improved 3D picture quality compared to last year’s LE925 TV? rev-conf.org will find out in this Sharp LE830 review.

Our first impressions

Sharp LE830 is extremely slim and the bezel is thinner than ever. Sharp has also chosen to ditch the glass front design from last year’s LE820 range, creating LE830 with a matte panel instead.

The stand is made from metal with a plastic layer in top but it feels solid. It also has a manual swivel function.

Only a few analog inputs such as s-video, component and scart are pointing out towards the wall. All other “important” inputs such as the TV signal plug, HDMI, USB and Ethernet are pointing to the side or down. Fair enough.

Test tools

Our TV signal is DVB-S (satellite) from Canal Digital and DVB-T (terrestrial). We also have an analogue TV connection. Testing is done with the DVE (digital video essentials) and Peter Finzel test DVD. Testing is also done with DVD, TV, Blu-Ray and Media center/PC.We use our own monitorTest. The software supports some of the traditional test patterns used to evaluate displays as well as some new and unique test patterns developed by the people here on rev-conf.org.Sony PlayStation 3 is our Blu-Ray player.All contrast measurements are based on the ANSI methodology.

Functionality

The remote control has not changed much and it is pretty much identical to last year’s version. I still feel that it lacks weight and quality but it is far more elegant that Sharp’s previous remote controls that were nothing short of hideous.

Time Shift recordingLE830 comes with Time Shift functionality which basically means that you can set live TV broadcasts on pause. But unlike last year’s LE820 and LE925 models, LE830 needs an external USB stick. It has no built-in memory. The USB stick is easily installed on the back of the TV with one of the three USB inputsAfter formatting the USB stick (it will be formatted to work only with the TV – you cannot transfer anything to a PC) you are set ready. Now you can press the pause button to pause live TV or you can press rewind to catch up if you were distracted in the middle of a show.DLNADLNA is accessed through the source menu and Sharp supports streaming of music, pictures and a range of video codecs (see Sharp’s web site for the full list).

I used Twonky to get a working DLNA connection and it ran pretty smoothly. Navigation is fast and east but loading time is too long. You can see the DLNA interface in the picture above.NET+Together with Philips and Loewe, Sharp has developed the so-called NET+ internet platform. The three TV giants hope to attract developers by using a common platform but unfortunately – or so it seems – they have not had much luck yet. Sharp’s NET+ platform only has a few services (Apps) and none of great importance. Sharp promises a new video store with movie rentals in July. However, we were not able to test the video store functionality. A video store could add much more value to the platform depending on the catalogue but we still hope to see more Apps on Sharps’s internet connected TVs in the future.

We were connected through an EU link so obviously we did not have access to for example Netflix. But it seems that Sharp has better offerings in the US with Vudu, CinemaNow and Netflix.There is also a built-in web browser. Below you see the rev-conf.org web site. Please notice that the flash menu to the left and the flash header at the top have not been loaded because the web browser has no native flash support.

Besides that I am not really impressed with the NET TV platform. The loading screen pops up often and we could wish for a more user friendly navigation. Samsung ((here) and LG’s ((here) Smart TV offerings seem to offer more value.Calibration settingsIn the menus I found these calibration setting options: OPC, backlight, contrast, brightness, color, tint, and sharpness.In the advanced menu you”ll find CMS hue, CMS saturation, CMS value, color gamut range, color temp, scanning backlight, gamma adjustment, film mode, active contrast, DNR, monochrome and range of OPC.You can also select from these picture modes: Auto, Dynamic, Dynamic, Standard, Movie, Game, PC and User.

Energy consumption

Compare power consumption measurements on different TVs and monitors with our interactive power consumption applet here.Below I have measured energy consumption on the 46 inch version.

Standby 0.1 W 0.1 W
SD+HD 71 W 69 W
3D 81 W 81 W

After calibration I measured power consumption to just 69 W. That is impressive for a 46-inch TV and lowerhan Samsung’s D8000 LED model.I have also included a 3D energy consumption. In the 3D mode the backlight is often maxed out to compensate for the reduction in light from the 3D glasses. Therefore the 3D mode also typically consumes more energy. In the 3D mode LE835 consumes 81 W.Also, please note that the flat panel TVs uses less power after calibration. This is common on flat panel displays because many picture parameters are reduced during calibration.

Calibration on Sharp LE830 / LE835

Below you can see an out-of-box measurement in the Standard picture settings without the Eco mode.

*

The graph says this:The number on the left is the delta value. Delta is a difference between two factors; here it’s the difference between the measured color on the panel and the actual color that is our target.A delta value lower that 2 results in a visible deviation from the actual color.A delta value over 4 or 5 results in wrong colors.A delta value between 1 and 2 results in precise but not perfect colors. A delta value lower than one results in almost perfect colors. The target is 0.Everything between 0 and 1 is barely visible to the human eye.The out-of-box settings are not very accurate and that is very common on TVs nowadays. The bright colors are too bright and the dark colors are too dark. Brightness is measured to 263 cd/m2 which means that pictures are too intense.The color temperature is also too high at 10834 Kelvin, which means that colors are too cold and bluish.I selected the Movie picture preset next and took a new measurement.

*

The movie preset is much better and actually quite good. It does not compare to for example THX presets but if you compare the movie preset to last year’s movie preset on Sharp LE820, you will definitely see that Sharp has made progress. Last year we criticized LE820 and the Quattron panel technology for having a green push in color reproduction and we were not able to eliminate it even after calibration. But LE830 is better and it seems that Sharp has focusing on improving the sub pixel color correlation in the Quattron panel technology with the new 2011 range.LE830 has no such green push and instead pictures on LE830 are too warm and reddish because of the too low color temperature – this is very common on TVs so this is no problem really. In the movie preset we measured gamma rising from 2.25 in the bright tones to 2.4 in the dark tones, meaning that both dark and bright colors are a bit too dark – nothing critical.I was therefore interested to see how accurate colors I would be able to achieve after calibration and below you can see my measurement.

After calibration I managed to improve color accuracy even further. Gamma is now also very close to our 2.2 target, which ensures accurate color accuracy.We also managed to get the color temperature closer to our 6500 Kelvin target and measured 6478 Kelvin after calibration.I am very satisfied with the calibrated result. Sharp has improved the color reproduction compared to their first generation of Quattron panels that had a distinct green push. LE830 has far more accurate colors and we are always happy to see accuracy in color reproduction because it is one of the most important aspects of picture quality.Also, please notice that I only used the basic RGB (red, green, blue) gain (called HI) and subset (called LO) color settings during my calibration. LE830 has more advanced 10 IRE color settings options and if these are taken into use I am sure that color accuracy on LE830 can reach near-perfection.Below are my calibrated settings.
