Great colors and excellent picture quality are two of the main factors that help create immersion while you’re gaming. Despite the importance of good color, monitor manufacturers don’t always calibrate the color of 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 scenarios.
Here are the results for the Gigabyte FV43U.
NOTE: Gigabyte has pre-calibrated this monitor to an average DeltaE <2 – see image below
Like always, we started the color accuracy performance section by running a preliminary test on the FV43U right out of the box. For this monitor, the ‘Standard Mode’ preset was installed, setting the brightness to 152.77 candelas – slightly over the recommended luminance for everyday usage.
Looking at the results above, the Gigabyte did seem a little disappointing when compared to the IDEAL figures. For a start, the White point measured in at 7478K, almost 1000 over the 6500K ideal. That said, black depth was pretty impressive, resulting in a 0.0353 score. Contrast ratio was above the marketed specifications (4331:1), but average deltaE fell short of the mark, only offering an average of 3.82 – making the ‘Standard mode’ preset poor for any form of color-accurate work. Gamma measured in at 2.25.
I decided to load the factory-calibrated sRGB preset hoping for better results. As you can see, the FV43U did become much more accurate in this color mode. We measured a 1.75 average deltaE which, despite not being the best we’ve ever tested, was still under the <2 that Gigabyte specified. White point was still poor and contrast ratio took a dip to 3688:1. That said, black depth was still solid at 7820K. Gamma measured in at 2.29.
There was a tonne of other presets inside the monitor’s OSD, but few offered accuracy that was close to the sRGB spectrum. That said, we did take some notes on the preset which are below:
FPS – The FPS mode offered up a blueish hue and more saturation in the blue and green regions. The colors weren’t nearly as accurate as the sRGB preset, but FPS did off good contrast for the most part.
RTS/RPG – This color mode was the most dramatic, offering up a darker profile that focused more on contrast ratio than color saturation.
Movie Mode – Colors seem to have a slight saturation applied when compared to FPS and RTS modes. The colors seem well balanced, offering a more pleasant viewing experience.
After testing the various presets, I wasted no time and decided to calibrate the panel – recording color gamut, panel uniformity, and overall color accuracy.
I selected the ‘User’ settings for the calibration, changing the RGB values to 99/87/97.
Here are the results:
Like always, after testing the monitor in various preset modes, we calibrated it to see how accurate the color reproduction could be. As you can see from the graph above, the results were a little bit disappointing once again. Normally we expect to see average deltaE drop to around 0.2-0.4. However, for this monitor, the best we recorded was 1.12 – decent, but by no means the best we’ve seen. We still recorded a maximum deltaE of 3.18 – more than what is deemed acceptable for color-accurate work within the sRGB spectrum.
That said, black depth and contrast ratio still remained strong – something that is not always the case after calibration. White point was still a little low, but overall was an improvement over out the box and sRGB presets.
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.
The panel uniformity for this monitor was OK but did have some obvious anomalies – as you can see from the results above. The majority of the screen showcased a ‘green’ score – offering good panel uniformity in both luminance and deltaE. The corners were the obvious anomalies, showcasing poor scores when compared to the rest of the panel. This is fairly standard on VA panels. However, with a 30% deviation in luminance, it can often be seen via the naked eye.
Viewing angles were to be expected from a panel of this technology. The VA technology doesn’t offer the best viewing angles, with color shift and brightness deviating on a fairly obvious scale. See video below.
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:
Taking a closer look at the color gamut measurements, the FV43U clearly exceeds the sRGB, Adobe RGB, and DCI-P3 spectrums. After calibration, the monitor exceeded 174% sRGB gamut volume – equating to a 99.5% coverage. Both Adobe RGB and DCI-P3 spectrums were exceeded by 19.9% and 23.3% respectively. That resulted in a 99.6% Adobe RGB and 94.1% DCI-P3 color gamut coverage.
Looking at the physical gamut graph, you can see where on the color chart the FV43U exceeds the sRGB spectrum – showcased by the dotted line. The FV43U color gamut didn’t quite cover the blue corner of the sRGB space, often the case in modern LED panels.
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:
|100% Brightness||735.46 cd/m²|
|0% Brightness||75.21 cd/m²|
|7 Brightness||120 cd/m²|
