Every model from the new Samsung Touch of Color series leaves a highly positive impression with their beautiful exterior, good ergonomics and neat setup. All of this makes them a good choice as all-purpose monitors for home. It is the 21.5-inch and 23-inch models with a Full-HD resolution of 1920x1080 pixels that deserve more interest. They are good for work, movies, games, everything. The 20-inchers should be viewed as inexpensive solutions because of their rather odd resolution of 1600x900. Thus, they are only suitable for games. You want a larger picture for watching movies today and even for working with documents (try opening two documents side by side on monitors with resolutions of 1600x900 and 1920x1080 pixels, and you will see the difference right away). The difference in price, for example, between the P2050 and P2250 is only about $50, which is negligible considering that you choose a monitor that is going to serve you for the next few years.
A 21.5-inch monitor with a resolution of 1920x1080 will have a very small pixel pitch. This ensures better sharpness and smoothness of lines, but fonts and other interface elements will look small. You should take this into account when making your shopping decision.
So, what is the difference between the 50 and 70 series besides their design? The following table contains the results of my tests for them.
Here are the points of difference:
- Brightness: the 50 series is somewhat better. However, a brightness of 200 nit is already high enough for every application unless you are going to watch movies under direct sunlight.
- Contrast ratio: almost the same
- Response time: the 70 series is faster, especially in the Fastest/Movie mode, but has a higher level of RTC-provoked visual artifacts. The difference in the Faster/Still mode is smaller whereas the Fastest/Movie mode cannot be recommended for use in any model, except for the XL2370, due to its high level of RTC errors.
- Color gamut: identical (a little different in the LED-based XL2370)
- Backlight nonuniformity: the 50 series has a very small advantage in average values and a larger advantage overall because brighter zones are more conspicuous on the 70 series.
Thus, it turns out there is no fundamental technical difference between the 50 and 70 series. The 50 series is even a tiny bit better in some aspects. This also refers to the newest XL2370 with its backlight based on white LEDs.
Summing it up, it is the exterior design that you should evaluate when choosing between the 50 and 70 series. You may like the bold contours of the 50 series or the elegance of the 70 one. Or perhaps you will be enticed by the extra-slim stature of the XL2370.
