Samsung U28H750 ‘4K’ UHD monitor with Quantum Dots
For users interested in a reasonably large screen that supports the ‘4K’ UHD resolution (3840 x 2160) but doesn’t break the bank, the 28” models with TN panels are often popular choices. In fact the first ever UHD model we reviewed, the Samsung U28D590D, used such a panel. A newer model was released that was rather similar aside from the addition of AMD FreeSync support; the U28E590D. The U28H750 (UH75 series) builds on these models with re-worked aesthetics and the use of a new panel. The monitor has a brushed-metal effect bottom bezel and Y-shaped stand, with a standard and moderately thick (by modern standards) bezel design. This is dictated by the panels themselves, which tend to have a fairly chunky panel border compared to some panels. The OSD (On Screen Display) is controlled by a JOG button or joystick at the rear of the monitor, towards the right side.
The monitor uses a 27.9” panel, likely a newer variant of the InnoLux M280DGJ-L30 used on previous 28” TN UHD models. This likely includes a medium (or ‘relatively light’) matte screen surface, like the older models, which provides effective glare handling. A 1000:1 static contrast ratio is specified and 170°/160° horizontal/vertical viewing angles as typical for a TN panel. A refresh rate of 60Hz is specified, although Adaptive-Sync is also supported and therefore so is AMD FreeSync on compatible GPUs. The variable refresh rate range of this is currently unknown, but it’s possibly the upper limit is slightly above the specified 60Hz. 10-bit colour is supported, likely through 8-bit + FRC dithering, and a flicker-free Quantum Dot LED backlight is employed. This provides a typical maximum luminance of 250 cd/m². It also gives a superior colour gamut than previous models, enriching vibrancy and enhancing oversaturation. It will avoid the sort of heavily saturated look of conventional wide gamut models (i.e. even wider colour gamut) displaying standard sRGB content, however. A 1ms grey to grey response time is specified, as with the previous models, which should of course be taken with a grain of salt.
The monitor includes the ‘Eye Saver Mode’, which is a specialised Low Blue Light (LBL) setting which creates a warmer, dimmer and significantly lower contrast image which should be more relaxing to look at. For users who wish to retain decent contrast and brightness control, the alternative ‘Warm2’ setting will also be included. This also reduces blue light output, making for more relaxing evening viewing for example. The included stand is tilt-only, but 100 x 100mm VESA holes are included for alternative mounting. The ports include; HDMI 1.4, HDMI 2.0, DP 1.2 (supports Adaptive-Sync), 3.5mm headphone jack and a DC power input (external power brick). The HDMI 2.0 port may also support Adaptive-Sync and hence AMD FreeSync, although that is currently unknown. It will at least allow this model to be used with ‘4K’ capable games consoles, however.
Further information on the monitor can be found on Samsung’s website. Global availability is expected shortly, with a retail price of around $400 USD. If there is sufficient demand, we’ll look to review this model.
