Gigabyte F127Q-X Gaming Monitor Review


Great colors and excellent picture quality are two of the main factors that help create immersion while your gaming. Despite the importance of good color, monitor manufacturers don’t always calibrate the color fo their panels to what is deemed accurate within specific color spectrums – sRGB/Rec.709 for example.

We like to test each monitor for color reproduction to see how they would perform in color-accurate 0scenarios.

Here are the results for the Gigabyte F127Q-X:

Like always, we started by testing the monitor right out the box. For users who don’t like to tamper with color settings in the OSD, this is a pretty important factor. The factory settings for this monitor are as follows; 110 candelas of brightness, ‘normal’ color temperature, and ‘low blue light’ set to 0. Out of the box settings are perfectly acceptable for long gaming sessions, putting little strain of your eyes.

Out the box, colors were not the best if truth be told. Whilst white point and black depth both showcases decent scores, average deltaE was pretty poor. On average, we saw a 4.91 color accuracy score, making it unsuitable for editing photo or video.

I tested the sRGB preset in the OSD next, expecting much better results. As you can see from the chart above, the sRGB seemed to be calibrated to a decent level, offering up excellent average deltaE. White point was a little high, but nothing overly substantial. Black depth and contrast ratio were both OK, with gamma set to 2.22.

This monitor comes equipped with an AORUS color preset that, despite not being very accurate, looks fantastic. It offers a vibrance boost and a gamma-rich viewing experience that really is very nice. It is a little on the blue side, but you soon get used to it. From a color accuracy stand point, this preset is far from accurate, posting a 5.91 average deltaE. Gamma wwas set to 2.17.

We finished the preset tests with the movie preset. It offers good white point and black depth – with a slight dip in contrast ratio. Average deltaE was again poor, measuring in at 5.15. Again, as this is a custom preset that tries to accentuate the viewing experience, there really isn’t anything wrong with this preset.

After testing the various presets, I wasted no time and decided to calibrate the panel, recording color gamut, panel uniformity, and overall color accuracy.

We chose the ‘Custom 1’ color setting and altered the RGB to 100/94/97. For users that like to save multiple presets, the F127Q-X offers 3 custom profiles that are saved to the onboard memory of the monitor.

Here are the results:

We calibrated the monitor and measured it against the sRGB preset the monitor already offered. The difference between the two was slightly noticeable, but not by much. We managed to increase the white point to 6598K and drop the black depth to 0.13. Contrast ratio was still a little low, but average deltaE was an impressive 0.26 – with a max reading of 1.35.

Despite getting a better score using the colorimeter, the F127Q-X’s sRGB preset offered an equal colour reproduction. Using this preset would be perfectly acceptable for color accurate work.

Panel Uniformity

Panel uniformity is a test we run to check how uniform the luminance and color is across the entirety of the screen. During this test, the center square is used as the reference space. Every other square is then tested to see how far it differentiates from the reference.

In an ideal world, we want every square to be green, meaning it hasn’t broken the differential threshold – something we can set at the start of the test.

Note: results will differ from panel to panel.

I was happy with the uniformity this panel offered, scoring highly in every quadrant we tested. As you can see from the results above, the F127Q-X offered a majority ‘green’ score – meaning the deviation was under deltaE of 2 (on average).  That makes this monitor extremely good for viewing content that has large blocks of solid color – sporting events or the likes.

Viewing Angles

Like other monitors making use of IPS panels, the Gigabyte F127Q-X provided extremely good viewing angles – well past what would be required for multiperson usage. Even at around 65+ degrees, you could still easily see the content on screen, with very little deviation in both luminance and color.

Color Gamut

As part of the calibration process, the DisplayCal will give an accurate measurement of the color gamut the monitor can provide. Below are the results of the color gamut test:

Color Gamut coverage

As you can see from the results above, the Gigabyte F127Q-X offers a wide color gamut that far exceeds the sRGB space. We recorded an impressive 163.3% sRGB coverage during tests, putting this at the top of color gamut spectrum –  for gaming monitors we’ve tested anyway. That equates to 99.8% sRGB, 99.7% Adobe RGB, and 91.6% DCI-P3 coverage.

Color Gamut Graph F127Q X

Looking at the physical color gamut graph, you can clearly see how far the color gamut of this monitor extends past the sRGB space – displayed by the dotted line. This simply means that the F127Q-X will be able to display a great range of colors when compared to lesser alternatives.

Maximum And Minimum Brightness

We ended the color accuracy and picture quality testing by checking the maximum brightness, minimum brightness, and 120 candelas points on this panel. The results are below:

Brightness Candelas
100% Brightness 435.83cd/m²
0% Brightness 41.79cd/m²
17 Brightness 120 cd/m²
