Warp and Blend are interfaces exposed in NVAPI for warping (image geometry corrections) and blending (intensity and black level adjustment) a single display output or multiple display outputs
Many display applications benefit from combining multiple projectors or displays into one larger display surface. If all the displays are aligned in a grid with no overlap, features like Mosaic make it easy to create a single unified display from multiple physical displays. When the displays are rotated at odd angles or the display surface is an irregular shape, multiple projectors need to overlap, blend together and be mapped or adjusted to the display surface. The Warp and Blend SDK provides an easy way to bring this functionality to any application with minimal performance impact and no incremental latency.
Released in July 2011, NVIDIA Quadro 4000 for Mac desktop workstation Graphics Processing Unit makes use of Fermi architecture, and is produced on 40 nm manufacturing process. The card's processor and graphics clock speeds are 950 MHz and 475 MHz respectively. It also features 256 CUDA cores, 32 texture units, as well as 32 ROPs. In order to run macOS Applications that leverage the CUDA architecture of certain NVIDIA graphics cards, users will need to download and install the driver for Mac located here.
In the example above both warp and blend are used to achieve a seamless, blended picture from two projectors illuminating a curved screen. A standard practice when using multiple projectors is to overlap the seams where each projected image touches another. Since optics and screens are never perfect and overlapping can create hotspots (regions gets twice amount of light) blend is used to adjust the intensity of the overlapping region. Warp is used to modify geometry so that it matches the curve of the projection wall.
Traditionally, warp and blend operations are done with custom hardware using features built into the projector or with direct modifications to an application. The Warp and Blend SDK provides an easy way to bring this functionality to any application with minimal performance impact and no incremental latency.
Warp and Blend is part of NVAPI
NVAPI is NVIDIA's core software development kit that allows direct access to NVIDIA GPUs on windows platforms. Warp and blend is implemented as an interface in NVAPI that programmably exposes warping and intensity adjustment features before the final scanout. Working in conjunction with a supported NVIDIA Display Driver, the warp and blend features works on a single screen, multiple screens and multi-gpu configurations and are available only with NVIDIA Quadro GPUs.

Why do Warp and Blend on the GPU?
Traditionally, warp and blend is integrated into the projector or done using custom hardware appliances which adds performance delay to the display pipeline. It can also be done using software applications but that may not conform to all use cases. Since the pixel information is already available to the GPU, the GPU is the natural place to do this work. GPUs also bring additional benefits to warp and blend:
- GPUs are inherently parallel for fast image processing operations
- Ability to perform transformation in the display pipeline before the pixel get scanned out
- Minimal performance delay to display pipeline compared to external boxes using FPGAs
- Cost effective and easily scalable

Release 342.01 is an update from the R340 ODE driver branch, the ‘Optimal Drivers for Enterprise’ [ODE]. ODE branches are dedicated to relatively long term stability for ISV certification, OEMs, and Enterprise customers. View full NVIDIA Quadro NVS 295 specs on CNET.
• Added support for the following GPUs: • VGX K1 • VGX K2 • Added a missing 32-bit compatibility library for libnvidia-opencl.so to the 64-bit Linux installer package. • Fixed a regression in backlight control functionality on some notebook configurations. • Fixed a performance issue with recent Linux kernels when allocating and freeing system memory. • Fixed a bug that sometimes prevented the display device / X screen selection menu from being displayed in nvidia-settings. • Fixed a bug that prevented X driver gamma manipulation from working after a VT-switch on some configurations. • Added the option '--output-file' to nvidia-bug-report.sh to allow specifying a custom filename for the log file.
• Fixed a hang when using OpenGL programs with some SLI Mosaic configurations on pre-Fermi GPUs. • Added sections to the 'Supported NVIDIA GPU Products' list for NVS, Tesla, and VGX products.
Note that many Linux distributions provide their own packages of the NVIDIA Linux Graphics Driver in the distribution's native package management format. This may interact better with the rest of your distribution's framework, and you may want to use this rather than NVIDIA's official package. Also note that SuSE users should read the SuSE NVIDIA Installer before downloading the driver. Installation instructions: Once you have downloaded the driver, change to the directory containing the driver package and install the driver by running, as root, sh./NVIDIA-Linux-x86_64-304.64.run One of the last installation steps will offer to update your X configuration file. Either accept that offer, edit your X configuration file manually so that the NVIDIA X driver will be used, or run nvidia-xconfig Note that the list of supported GPU products is provided to indicate which GPUs are supported by a particular driver version. Some designs incorporating supported GPUs may not be compatible with the NVIDIA Linux driver: in particular, notebook and all-in-one desktop designs with switchable (hybrid) or Optimus graphics will not work if means to disable the integrated graphics in hardware are not available.
Ntfs driver for mac. Hardware designs will vary from manufacturer to manufacturer, so please consult with a system's manufacturer to determine whether that particular system is compatible. See the for more detailed instructions.
For people who have Dell T3500/R5500 and anything in that era of computers that use the NVidia Quadro NVS 295 you have download a Windows 10 x64 driver from NVidia.com. I have attached a driver link below however if you wish to obtain it your self you have to go to the driver download page specific options listed below. Product Type: 'Quadro' Product Series: 'Show all Product Series' then select 'Quadro NVS Series' Product: 'Quadro NVS 295' Operating System: 'Windows 10 64-bit' Select the options that are applicable to your use and search.
It should return Driver 342.00 released on 2016.10.27. Yes I did get an error message but I apologize I did not capture it as it was a splash screen and then rebooted several times before allowing me the option to try something else. IE advanced boot options. No I did not try installing in compatibility mode as it was NVidia's driver stating it was for Windows 10 and the Microsoft Update download driver didn't even give me a choice. Since this was my work computer I had to revert back to the original OS installed.
