19 24-inch full hd monitors review: affordable view

Even with a limited budget you can purchase an excellent monitor


Colour quality

We perform a lot of measurements for the colour quality, but once again we keep to the most important tests here. The detailed results can be found on the product pages of the tested monitors, including screenshots of the Calman software. 

To start off we take a look at the coverage of the sRGB colour space. The better this is, the more saturated the colours are. We find that tn-monitors are primarily in the bottom half of the graph, although the Iiyama GE2488HS-B2 is a positive exception. The AOC i2475PXQU and the Philips 24E7QDSW perform the best here. That said,  the four models below that – which includes all three Samsung monitors – perform excellent as well.

We also take a look at the colour temperature of white with the standard setting. A value of 6500 K is preferred for a neutral colour quality that corresponds to what you can expect with daylight. Most participants perform well here, but the AOC i2475PXQU and the LG 24MP58VQ-P are clearly too high which results in a light blue cast. The LG 24MP48HQ-P and 24MP67VQ are slightly too low, with a ruddy cast as a result.

Following that we take a closer look at the colour deviation based on the CIE2000 norm. We conform to an upper limit of 3 for what we find acceptable for image editing, a limit of 5 for what is not yet bothersome – anything above that does not make us happy. The good news is that only four models are in this category. Of these, the Benq GW2470H clearly shows better results in sRGB-mode – for that reason we will show that graph as well. First with the standard mode:

And the results in sRGB-mode, if possible – which is the case with 8 models. Note that most only show small differences.

Next up: the grayscale deviation. This is often harder to truly get right, and deviations are less visible – except in white and grayscale. We do see quite a few models with very solid results, especially the Samsung S24F350FH and LG 24MP88HM-S, Samsung S24D330H and the C24F390FHU of the same brand perform well. The same can be said of the Philips 246E7QDSW, while the Benq BL2405HT and the Acer RT240Ybmid can also be classified as very good. LG can also be found at the bottom, but none of the seven models at the bottom of this graph perform well here.

You can find detailed results of the colour measurements on the individual product pages of every tested monitor.


The gamma value for sRGB is 2.2 ideally. Deviations smaller than 0.2 are still acceptable, anything more than that becomes bothersome. A gamma that is too high results in loss of detail in darker parts, while a gamma that is too low has the same problem only in lighter parts. We also show the absolute gamma deviation in ascending order in a separate graph.

Below you can find that most models perform within bounds, although four monitors do go over these. Especially the Benq GW2470H has a gamma that is too high.
