<p>This driver release supports X screens with screen depths of 30
|
|
bits per pixel (10 bits per color component). This provides about 1
|
|
billion possible colors, allowing for higher color precision and
|
|
smoother gradients.</p>
|
|
<p>When displaying a depth 30 image, the color data may be dithered
|
|
to lower bit depths, depending on the capabilities of the display
|
|
device and how it is connected to the GPU. Some devices connected
|
|
via analog VGA or DisplayPort can display the full 10 bit range of
|
|
colors. Devices connected via DVI or HDMI, as well as laptop
|
|
internal panels connected via LVDS, will be dithered to 8 or 6 bits
|
|
per pixel.</p>
|
|
<p>To work reliably, depth 30 requires pixman 0.11.6 or higher.</p>
|
|
<p>In addition to the above software requirements, many X
|
|
applications and toolkits do not understand depth 30 visuals as of
|
|
this writing. Some programs may work correctly, some may work but
|
|
display incorrect colors, and some may simply fail to run. In
|
|
particular, many OpenGL applications request 8 bits of alpha when
|
|
searching for FBConfigs. Since depth 30 visuals have only 2 bits of
|
|
alpha, no suitable FBConfigs will be found and such applications
|
|
will fail to start.</p>
