Other panel-related specifications are what you’d expect from a 4K IPS monitor at this price range, and include a 300-nit peak brightness, a 1,000:1 contrast ratio, 10-bit color depth support and 178° wide viewing angles. The difference in pixel density (157 PPI) in comparison to the 27″ 4K models (163 PPI) is barely noticeable in fact, most people will prefer the slightly larger 28″ screen. The Samsung U28R550U covers 90% of the DCI-P3 color space, which is equivalent to around 125% sRGB gamut size, resulting in more saturated in rich colors. The Samsung U28R550U has a bit larger 28″ screen, so you get a tad lower pixel density than that of the Dell S2721QS, but you get a wider color gamut for more vibrant colors! Image Quality Basically, you can ignore its ‘HDR support’ as it can only accept the HDR10 signal and display it, which doesn’t really improve the viewing experience, nor does it increase the monitor’s price. HDR (High Dynamic Range) is supported as well, but due to the monitor’s limited color gamut, contrast ratio, and brightness, HDR is just simulated.

Luckily, most applications don’t have this issue, but it is something that you should keep in mind.īut here’s the kicker: other panel-related specifications include a 350-nit peak brightness, a contrast ratio of 1,300:1, 99% sRGB color gamut, and 10-bit color depth support for 1.07 billion colors! Note that the monitor is factory-calibrated! Note that if you plan on using the monitor for work, you need to make sure that your applications are able to handle scaling for instance, some apps can only scale by 100% or 200%, which would make your toolbar either too small or too big. Scaling will make these items larger (thus reducing screen real estate), but also sharper!

Now, such high pixel density will make everything tiny on your desktop, so you will need to use scaling to make small items such as text and icons readable. On a 27″ monitor, the 4K resolution pushes the pixel density to 163 pixels per inch! Want even sharper details on a 27″ monitor? Then check out the Dell S2721QS with 4K UHD resolution! Image Quality

IPS glow and mediocre contrast ratio (as expected from this panel technology).
