The TCL FS3750 doesn't look bad but its added labeling at the bottom part of the television frame and its fair thickness doesn't make it stand out.

Picture Quality

TCL FS3750 Picture Quality Main Picture

The TCL FS3750 offers a good but basic picture quality. It appears sharp no matter the content and dark scenes offer good details. The FS3750 has accurate colors. HDR, 4K, 3D, local dimming and other extras usually found on more expensive TVs are absent. It deals quite well with reflections. Unfortunately the picture quality degrades even when viewed from a slight angle.

Smart OS : Roku

With the integration of the Roku platform, the TCL FS3750 delivers excellent smart features with an overwhelming amount of available apps and very straightforward menu navigation. Even the TV settings, although scarce, are very simple to use and understand. The remote also helps with the simple experience with its minimalist design. People that likes to fiddle with a lot of options might be turned down by this approach but for the others, even the non-techy ones, the experience is great.

Compared to other TVs

TCL FS3750 Group Shot Picture
Top row, from left: Sony W600D (KDL32W600D), TCL FS3750 (48FS3750), TCL FS3800 (40FS3800). Bottom: Sony R510C (KDL48R510C), Vizio D Series 1080p (D50-D1), LG LF5500 (49LF5500). Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

TVs in the same price range of the TCL FS3750 usually don't offer as much smart features which makes the FS3750 kind of unique and somewhat hard to compare. Something is clear though, that amount of features combined with a picture quality this good is really hard to beat for the price.

Vizio E Series 2015
32" 40" 43" 48" 50" 55" 60" 65" 70"

The Vizio E Series 2015 is slightly better for watching movies of high quality (1080p), especially in the dark but falls short when it comes to low resolution content and smart features. For a mixed usage, the TCL FS3750 is more versatile and an even better value.

Sony R510C
40" 48"

The Sony R510C doesn't get as bright and loses even more of its picture quality when viewed from the side. It also has a very basic smart offering. The TCL FS3750 is a way better offering.
