jaberwacky Posted September 6, 2013 Share Posted September 6, 2013 (edited) I found these functions on MSDN which control various aspects of monitors such as brightness, contrast, color temperature, etc. This works on my monitors on Windows7 x64. Your mileage may vary. Doesn't work on anything lower than Windows Vista. Not all monitors are supported.Requires the latest AutoIt3 beta.[10-17-2013] -- The VCPs described in the MCCS standard are now wrapped up into Monitor Configuration Wrapper.au3. BE CAREFUL WITH THESE! I made this UDF without any real understanding of why. I do not foresee myself using these, but I put them out here in case someone else does. These functions are all untested. I leave it up to you to decide if the functions that you want to use have been implemented correctly.

Bluesmaster Posted January 1, 2015 Share Posted January 1, 2015 Can I receive the (hardware-)serial of the monitor providing a HMonitor (from "_WinAPI_GetMonitorInfo" etc...)

jaberwacky Posted January 2, 2015 Author Share Posted January 2, 2015 (edited) Well, there are several problems with this UDF. Not surprising considering that I just did this to be able put out a UDF where I did not see one before, without a 100% understanding of monitor technology. I did download and follow the standard though. Hopefully someone can build on this and make it work correct. You may be able to do what you ask. I don't know if the function I coded is coded proper or not. Have you gave it a try yet? Also, which function is it that provides this serial? Edit: the function (I believe) is: EDIDOperation. Edit Again: In case you want to try the original function and this new version: Func EDIDOperation(Const $physical_monitor, Const $block_number) Local Const $return = SetVCPFeature($physical_monitor, 0x78, $block_number) Return (@error ? SetError(1, @extended, False) : $return) EndFunc Edited January 2, 2015 by jaberwacky Helpful Posts and Websites: AutoIt3 Variables and Function Parameters MHz | AutoIt Wiki | Using the GUIToolTip UDF BrewManNH | Can't find what you're looking for on the Forum?

Bluesmaster Posted January 2, 2015 Share Posted January 2, 2015 Hi jaberwacky, At the beginning of my research I saw your UDF, I didnt work so 2-day journey of research followed. I was on WMI > "WmiMonitorID" which can read the serial but cannot associate it with a monitor number (this was hard to swallow) Now I took a deeper look into your UDF again. It the capabilities are amazing...but: GetNumberOfPhysicalMonitorsFromHMonitor() fails. Argh...it returns 0 for all handles. And throws no errors. I thought it might be a problem in your implementation so I tried implementations in other programming languages but all the same. ( I am on Win8.1x64 autoit v3.3.10.0 ) It might have something to do with my Monitor Configuration (DisplayPort > Adapters > Monitor) But on the other hand I found a c# project which can successfully save my monitor configuration using the dxva2: http://sourceforge.net/projects/monitorswitcher/ Do you have any idea what we can debug here to find the root of the problem? best regards Bluesmaster My UDF: [topic='156155']_shellExecuteHidden[/topic] Link to comment Share on other sites More sharing options...
MikahS Posted January 2, 2015 Share Posted January 2, 2015 Could have something to do with OP's first post. Edit: I found some issues with this UDF.

Bluesmaster Posted January 2, 2015 Share Posted January 2, 2015 @ Community Can some of the community test the following code quickly and post the results? I would like to know if it is a specific problem to my computer configuration #include <WinAPIGdi.au3> $physical_monitor = DllStructCreate("handle physicalMonitor;wchar physicalMonitorDescription[128]") DllCall( "Dxva2.dll" , "bool", "GetPhysicalMonitorsFromHMONITOR", "handle", _WinAPI_EnumDisplayMonitors()[1][0], "dword", 1, "ptr", DllStructGetPtr( $physical_monitor ) ) ConsoleWrite( @OSVersion & @OSArch & @LF & DllStructGetData($physical_monitor, "physicalMonitor") & @LF & DllStructGetData($physical_monitor, "physicalMonitorDescription") & @LF ) @ jaberwacky I used the "EDIDOperation". ...ok It reads the EDID-Block ( 12-15 = monitor serial number > http://en.wikipedia.org/wiki/Extended_display_identification_data ) But it only tells me that it succeded...now where is the data ? I know you are not an monitor expert...but honestly...who else should know if not you If we solve the problem we can also answer this thread: '?do=embed' frameborder='0' data-embedContent>> btw i recommend linking this in the op: http://msdn.microsoft.com/en-us/library/windows/desktop/dd692964(v=vs.85).aspx ( as I had my problems figuring out which api you are using firstly ) My UDF: [topic='156155']_shellExecuteHidden[/topic] Link to comment Share on other sites More sharing options...

jaberwacky Posted January 3, 2015 Author Share Posted January 3, 2015 (edited) I don't really know. Some forum posts seem to indicate that it can't be read this easily. But it seems that Windows can read it because it stores the EDID in the registry. So, I tried: Func EDIDOperation(Const $physical_monitor) Local Const $return = GetVCPFeatureAndVCPFeatureReply($physical_monitor, 0x78) Return (@error ? SetError(1, @extended, False) : $return) EndFunc ConsoleWrite(EDIDOperation($physical_monitor)[0] & @CRLF) To no avail. If the standard says that 78h is the VCP then I can't just say 0x78 can I? I have to convert it from hex to decimal, so 120? I tried it but I don't know if this is the reason it won't work or some other reason. Answered my own question. I follow the 0x convention in the example in the OP and that works fine so I assume I can just turn the h into a 0x.

Bluesmaster Posted January 3, 2015 Share Posted January 3, 2015 (edited) 1. OP example didnt work because GetPhysicalMonitorsFromHMonitor didnt work. (I thought but I tried with manual monitorNumbers "1", "2"...which is what GetPhysicalMonitorsFromHMonitor returns???) 2. 78h means 78hex means 0x78 3. You changed EDIDOperation to from GetVCPFeature in to GetVCPFeatureAndVCPFeatureReply which is better but for me returns [ 0 0 0 ] for any blocks and any monitorNumbers (and for you???) *found a small mistake in your GetVCPFeatureAndVCPFeatureReply > it returns [ $VCPCodeType $CurrentValue $CurrentValue ] instead of [ $VCPCodeType $CurrentValue $MaximumValue ] 4. Its no problem to read the EDID from registry but they are not in PhysicalMonitorNumber-order so I cannot correlate them to my monitors, which I intend 5. I tried it in virtual machine, doesnt work either. I think I will give up for the moment, which is very hard after so much time spend Edited January 3, 2015 by Bluesmaster My UDF: [topic='156155']_shellExecuteHidden[/topic] Link to comment Share on other sites More sharing options...
Bluesmaster Posted January 3, 2015 Share Posted January 3, 2015 what I forgot to mention is that GetPhysicalMonitorsFromHMonitor delivers the monitor name ( 2. DllStruct Entry ) which indicates that it is working somehow.. My UDF: [topic='156155']_shellExecuteHidden[/topic] Link to comment Share on other sites More sharing options...
jaberwacky Posted January 5, 2015 Author Share Posted January 5, 2015 Run this code please: #include "Monitor Configuration Wrapper.au3" Const $h_monitor = _WinAPI_EnumDisplayMonitors()[1][0] Const $_physical_monitor = GetPhysicalMonitorsFromHMonitor($h_monitor) ConsoleWrite(GetMonitorCapabilities($_physical_monitor) & @CRLF) If it returns 0 then your monitor doesn't support these functions.

Bluesmaster Posted January 5, 2015 Share Posted January 5, 2015 Hi, It returns 0. But that might be because of GetPhysicalMonitorsFromHMonitor returns 0 before. Also the c#-Project I meantioned (http://sourceforge.net/projects/monitorswitcher/) does use the same API with success. And I have several ( 7 ) very modern LED-Monitors which must support this standards. However, Monitorconfiguration is a very complex topic, and it might have somethink to do with my computer config. Anyway I dont die without these functions, and for everyone else this is great work done here and I could highly recommend this powerful udf. I just fear, your "I code the 0.9-version and anyone else will pick up and maintain it" is a bit illusive, and I would encourage you to take the main responsibility for the udf. But thats just my opinion (in bad english ) thank you & best regards Bluesmaster My UDF: [topic='156155']_shellExecuteHidden[/topic] Link to comment Share on other sites More sharing options...
