Samsung UN40EH6000F LED LCD HDTV Review$779.00
There are two motion processing modes on the Samsung UN40EH6000, Auto Motion Plus, and LED Motion Plus. Neither of these functions were commendable in any fashion. The Auto Motion Plus feature suffered from the many problems we frequently discuss, regarding the Soap Opera Effect. While causing problems for film based content, it also showed significant errors in our motion tests. The smoothness of the motion was excellent, retaining very fine details while in motion, but you would hardly notice this detail for all of the artifacts introduced to the picture.
Artifacts are any part of the picture that are not supposed to be there; images not inherent in the input signal that are displayed on the screen. At the start of every motion was some crazy pixel freakout, where chunks of pixel clusters showed some entirely opposite frame. We wanted to see if this jumbling of the picture was obvious when watching content, and we saw it there too. The noise we saw in our motion tests carried over into actual content, though it was less noticeable. Once we caught it though, it was hard not to see it in just about every moving object from people waving their hands to cars rolling down the street. We turned the Auto Motion Plus function off, and it corrected the pixel freak out, but the slanting and jagged edges increased.
The LED Motion Plus function claims to make for smoother motion in fast moving scenes. What we saw instead was just a dimmer screen. We tested this actually, and found that this function dropped the peak brightness by about 100 cd/m2 . That is almost half of the total brightness recorded on the screen, which would drastically reduce the contrast ratio. Further, we couldn't see any actual adjustment in the motion processing. Our best guess is that, by making the screen dimmer, it will be harder to notice all the damn artifacts. More on how we test motion performance.
3:2 Pulldown & 24fps
Standard film content is shot at 24fps (frames per second). 3:2 Pulldown refers to how well a television scales its native frame and refresh rates to match film-based content. The UN40EH6000 has a refresh rate of 120Hz, twice the refresh rate of standard television screens (60Hz), which means that natural film content must be imbued with numerous extra frames per second in order to maintain its original appearance. The Samsung UN40EH6000 suffered a lot of flickering and jittering when put up against our 24fps SMPTe pattern, but otherwise the image maintained an impressive smoothness. The UN40EH6000's Film Mode did little to correct these difficulties, but was definitely noticeable during moving, video-based content; in fact the UN40EH6000 scored higher than average during this test--with or without Film Mode--with very little noticeable frame rate correction or lagging content. More on how we test 3:2 pulldown and 24fps.
The Samsung UN40EH6000 is a native 1080p television, and naturally shows no problems with 1080p content. But since most broadcast content is not yet processed at 1080p quality, we tested how well the UN40EH6000 maintained its resolution at 720p and 480p, the broadcast resolution for high-definition and standard-definition content. More on how we test resolution scaling.
The Samsung UN40EH6000 tested at 3% vertical overscan and 2% horizontal overscan, with screen settings such as 16:9 or Screen Fit doing nothing to fix this. There was a little banding during our moire interference test, but overall the UN40EH6000 maintained top legibility and resolution for 480p content. To achieve the best picture (with 0% overscan!), it is recommended that you set the screen to 4:3 aspect ratio, as this is the natural setting for all 480p content.
720p resolution is where the Samsung UN40EH6000 really tripped over its cables. While initially eschewing some overscan problems, we discovered that changing the resolution from native 1080p to 720p also changed the Screen setting from "Screen Fit" to "16:9". Changing back to Screen Fit fixed the overscan, but nothing could be done in the way of pixel banding. The 720p setting is much better than some HDTVs we've seen, but the Samsung UN40EH6000's overall score was dropped in this area due to some of the worst pixel reproduction (short of total illegibility) possible. Despite this, the 720p content resolution was as good as its 1080p resolution, and text legibility was (surprisingly) even better.
1080p is the native resolution of the Samsung UN40EH6000, and thus its score in this area is just shy of perfection. There was (obviously) no overscan, no pixel banding, and perfect resolution. The only complaint we had was that text below a 9-point font was slightly less legible than we'd have liked.
