What is True Color Mode? True Color Mode (4:4:4) is an exclusive feature of the performance version. For basic personal and professional versions, without ultra-high definition and high frame rates, the effects of True Color Mode are limited. This feature is primarily suitable for various types of designers, effectively solving color distortion problems caused by performance differences between the master and slave hardware devices during remote operation.
As we all know, when choosing a TV in a store, even though the salesperson used the same source file for the projection display, different models and screens show color differences. For example, if we're working overtime at home, the master device A might display a magenta color, but when we return to the office the next day, the slave device B might display a pinkish hue, completely changing the texture. This requires time and effort to readjust and recreate; it's annoying and might even delay task delivery, causing a chain reaction.
True Color mode utilizes 4:4:4 color image processing technology, a high-performance image processing technique that combines high-bandwidth transmission and high-quality color sampling to provide excellent image quality and color accuracy, reproducing more delicate colors than the original.
4:4:4, 4:2:2, and 4:2:0 represent chroma sampling methods. Chroma sampling is used when digitally sampling analog component video or YUV signals; we can also see these values in camera parameters. Regarding 4:4:4 sampling, let's understand what these numbers represent: the first "4" represents 4 columns of pixel information, the second "4" represents the first pixel information, and the third "4" represents the second row of pixel information.
The effect of sampling 4 luminance values corresponding to 4 chroma values is shown below. It can be seen that the image information obtained through 4:4:4 sampling is identical to the original information, with no information loss, and the image quality is the best. The corresponding result is that the image quality is as follows: 4:4:4 > 4:2:2 > 4:2:0; 4:4:4 is lossless sampling, 4:2:2 sampling loses half of the image information, and 4:2:0 sampling loses three-quarters of the image information.
How to enable True Color Mode? First, you need to upgrade your ToDesk account to the performance version. After successfully establishing a remote connection, click to enable it in the [Display] section. Note: The master and controlled devices must be upgraded to version v4.6.0 or higher, and the controlled device must support an NVIDIA dedicated graphics card. If the graphics card version is insufficient, you need to upgrade the graphics card driver.
When using it, enabling this mode in a timely manner will help make the color effect of remote operation more accurate; if there are other design modification needs, you can also connect a graphics tablet plugin as needed. The current user experience is basically the same as the experience in front of the controlled device.
The addition of True Color Mode (4:4:4) undoubtedly brings a more professional color solution to remote control scenarios. Whether you are a designer, photographer, or content creator with an extreme pursuit of image detail, this feature can help you break down device barriers and achieve "what you see is what you get" color reproduction.
