The term quad buffering is the use of double buffering for each of the left and right eye images in stereoscopic implementations, thus four buffers total (if triple buffering was used then there would be six buffers). The command to swap or copy the buffer typically applies to both pairs at once, so at no time does one eye see an older image ...
Direct3D does not implement a most-recent buffer swapping strategy, and Microsoft's documentation calls a Direct3D swap chain of three buffers "triple buffering". Triple Buffering as described above is superior for interactive purposes such as gaming, but Direct3D swap chains of more than three buffers can be better for tasks such as presenting ...
In Windows 7 and later, significant hardware changes (e.g. motherboard) may require a re-activation. In Windows 10 and 11, a user can run the Activation Troubleshooter if the user has changed hardware on their device recently. If the hardware has changed again after activation, they must wait 30 days before running the troubleshooter again.
1 = with serrations (H-sync during V-sync). Bit 1: Sync on red and blue lines additionally to green 0 = sync on green signal only; 1 = sync on all three (RGB) video signals. Bits 4–3 = 10 Digital sync., composite (on HSync). If set, the following bit definitions apply: Bit 2: Serration. 0 = without serration; 1 = with serration (H-sync during ...
The most common solution is to use multiple buffering. Most systems use multiple buffering and some means of synchronization of display and video memory refresh cycles. [3] Option "TearFree" "boolean": disable or enable TearFree updates. This option forces X to perform all rendering to a back buffer before updating the actual display.
The original FreeSync is based over DisplayPort 1.2a, using an optional feature that VESA terms Adaptive-Sync. [9] [10] This feature was in turn ported by AMD from a Panel-Self-Refresh (PSR) feature from Embedded DisplayPort 1.0, [11] which allows panels to control its own refreshing intended for power-saving on laptops.

A framebuffer (frame buffer, or sometimes framestore) is a portion of random-access memory (RAM) [1] containing a bitmap that drives a video display. It is a memory buffer containing data representing all the pixels in a complete video frame . [ 2 ]
In digital electronics, a tri-state or three-state buffer is a type of digital buffer that has three stable states: a high output state, a low output state, and a high-impedance state. In the high-impedance state, the output of the buffer is disconnected from the output bus, allowing other devices to drive the bus without interference from the ...
