How to use NVAPI

My project is very simple one to all of you. I have 2x2 set with NVS510. Upper two displays are flipped and the lower two are landscape position. I am intending to make one big screen using mosaic. But the mosaic can only handle landscape position displays.

Here, I checked Nvidia page and got to the point of downloading NVAPI to use NV_Rotate command in NVAPI.h.

My question is

  1. where am I supposed put Nvapi.h file

  2. what path to specify

  3. do I have to compile/

My OS is WIN7 pro 64 display resolution is 1920x1080

thank you for reading


I reached out to one of our engineers about your questions. The only way to support what you are asking for is via Warp & Blend API (which is part of NVAPI). Sample code/project files can be found here:

Also, note that you can point your project files to wherever you have put the NVAPI files. It doesn’t need to be “installed”.

Hi TomK,
Thank you for your reply. To tell the truth, there were some other users who had the same problem that I had and someone commented the same answer!!
This was how I got to NVAPI.
If you read through Warp and Blend page and kindly go through download process, I am sure you will see what I am trying to convey to you.
you are provided with download file, which is actually NVAPI files. with some samples. Before I ask my question on this page,
I have read through pretty much all the NVIDIA mosaic and display pages, including funky display introducing how to write coordinates and how to rotate. I have spent many hours reading web pages without any new valuable findings.

I have read your advised page and downloaded files, I got that. But the biggest problem to me is " how to put my NVAPI.h file so that my setting is interpreted".
Could you possibly show me a little bit more example. please.

I am not a computer specialist but I have at least enough graduate education in science from U.S. appropriate university. So I cannot help evaluating Nvidia web page very user “Unfriendly.”

Help me someone
