Download Driver Optoma Projector
Donnie Ehlen
Hi, would anyone happen to either have a serial (preferably) or IR driver for a Optoma HD66 projector or know a compatible model that the driver would work for basic functionality (on/off is really the only function I need) please? I tried 2 different Optoma serial drivers and 2 different IR and neither appear compatible with on/off codes surprisingly.
Hi, thanks for the offer, I appreciate it, but that projector ended up developing several stuck pixels (as you noticed the original post was from almost a year ago) so i replaced it with a BenQ w1070. Alan Chow had developed a serial driver which he posted in another thread which works great.
The Optoma Universal Driver for RTI allows for full control over most of the available Optoma projectors from the high end laser projectors, down to the entry level DLP's. The driver supports control over IP or RS-232 and is fully tagged and ready for quick programming in Integration Designer Apex.
In addition to comprehensive control, the driver provides feedback for current input and power state, lamp hours and system messages. Depending on the model you will have access to advanced features like HDR modes, 3D control, Audio control, setting triggers, even sending messages to the screen.
Optoma uses the same protocol for control over almost their entire range of projectors making this driver suitable for almost any configuration that you need.
DriverGuide maintains an extensive archive of drivers available for free download. We employ a team from around the world which adds hundreds of new drivers to our site every day. How to Install Drivers Once you download your new driver, then you need to install it. To install a driver in Windows, you will need to use a built-in utility called Device Manager. It allows you to see all of the devices recognized by your system, and the drivers associated with them.
If you are having trouble finding the right driver, stop searching and fix driver problems faster with the Automatic Driver Update Utility. Many computer problems are caused by missing or outdated device drivers, especially in Windows 11. If your deskttop or laptop is running slow, or keeps crashing or hanging, there is a good chance that updating your drivers will fix the problem. Automatic updates could save you hours of time.
Optoma, as any other manufacturer with RS232 interface, has a table of commands I can use. What is the most direct way to send these commands to the projector from HA that I can configure in simple yaml to have various buttons in my lovelace? Thanks!
As Tom above argues, of course the USB>RS232 worked. Tom Thanks!. Be careful, my problem was in Big Sur that has some bug that causes sending only two characters instead of the whole hex, so Mac OS Big Sur is not proper OS for testing. Windows needed some drivers. HA running on RP4 works like a charm. I used coolterm for testing from OSx, that worked once probably because of the bug (bug was identified by the author of coolterm app who helped me as well, thanks Roger!)
With that alone i do not get a 3D effect (i.e., viewing with the shutter glasses gives no 3D effect). In the vtk application i can see that there is a flickering (left/right image). You can also see that in the second image the Desktop mode hast the desired resolution and refresh rate BUT there is a active signal mode which is 3840x2160, 29,97Hz. The Beamer also displays that its set to 3840x2160, 30Hz.
Thats why i tried setting the parameters through the Nvidia Control Panel. There it gets set to 4kx2k, 1280x720 with 29Hz. If i try to set it here to something different, for example from the tab Ultra HD, HD,SD to 1280x720 on the PC tab with 120Hz it resets itself. Even other refresh rates or resolution just end up in a reset back to 4kx2k, 1280x720 with 29Hz. The projectors state for PC-3D-Timing that they can use 1920x1080 with 120Hz. I also checked the global 3D settings in the Nvidia Control Panel. Here i set stereo to ON and selected generic active stereo but i also tried Displayport In-Band Stereo. Do i need a different/additional setting?
What settings should i set and where should i set them. In Windows or only in Nvidia or somewhere else? And is there a tutorial to connect multiple projectors via one/two graphics cards which could help me here?
Personally I have no idea how to help you sadly, besides suggesting to start simple first to verify any working setup. For example just using one GPU with one projector and try out simple 3D video playback to find correct settings.
I am actively testing various combinations. I have also taken out the sync card and will now try it with just one graphic card.
Regarding 3D support, there is the option to enable stereo in the settings and different display modes (see picture).
So i hope the projector is then able to detect the 3D Input and can utilize DLP-Link for the shutter glasses.
