The connection panel includes four HDMI inputs but only one component video input. You also get a PC input and an RF input to access the internal ATSC and Clear-QAM tuners. The HDMI inputs accept both a 1080p/60 and 1080p/24 signal, and one is located on the side panel for easy access. Also located on the side panel is a USB port for JPEG and MP3 playback. The back panel sports an Ethernet port for a wired network connection; this model does not come with the USB-based 802.11n adapter that you get with higher-end lines like the UX600 Series.
The 40G300U offers a solid assortment of picture adjustments but lacks some advanced options, like precise white-balance controls, the Auto Brightness sensor that adjusts the backlight based on the room's ambient light, and the ColorMaster system that lets you individually adjust each color point. You do get five preset picture modes, as well as the option to enable a Gaming mode that improves response time when mating the TV with a gaming console. The menu includes three preset color-temperature options, as well as Blue and Green Drive adjustments that provide limited ability to fine-tune the TV's white balance. You can adjust the TV's backlight brightness via either a fixed backlight control or the DynaLight mode that automatically tailors the backlight to suit the source content. The setup menu also offers gamma adjustment and MPEG noise reduction. The ClearFrame control addresses the issue of motion blur, while the Film Stabilization mode deals with the problem of judder in film sources, using motion interpolation to produce smoother movement. Finally, the TV has eight aspect-ratio options, including a Native mode for viewing images with no overscan.
The 40G300U has a black frame with a tapered bezel and subtle gradation around the edges, as well as a rounded base and invisible speakers. The audio setup menu includes bass, treble, and balance controls, as well as QSound audio processing. It does not offer the Dolby Volume sound-leveling technology you'll find in higher-end models.Read more about the 40G300U on Page 2.
