Display Database: naming a monitor [ SOLVED ]

Hello.

Given a certain display ID of an opened screen (SA_DisplayID), how to retrieve the name of its associated monitor?
For example having a display ID corresponding to the mode "Radeon 9250:800x600 ARGB32", I need to get "Radeon 9250".

Thanks, regards

This is probably not quite what you're looking for, but here's what Composite3DDemo does to get the screen mode name:

struct MonitorInfo monitor;
IGraphics->GetDisplayInfoData(NULL, &monitor, sizeof(monitor), DTAG_MNTR, screenModeReq->sm_DisplayID);
 
printf("Opening screen: %s\n", monitor.Mspc->ms_Node.xln_Name);

There is a way to get just the graphics card's name, but I can't remember that right now.

I just remembered that GfxBench2D extracts this info. Here's the snippet:

		ULONG boardNum = IP96->p96GetModeIDAttr(displayID, P96IDA_BOARDNUMBER);
		const char *boardName = NULL;
		const char *boardDriverName = NULL;
		ULONG boardDriverVersion = 0;
		ULONG boardDriverRevision = 0;
		const char *chipDriverName = NULL;
		ULONG chipDriverVersion = 0;
		ULONG chipDriverRevision = 0;
		uint64 totalInternalMemory = 0;
		ULONG cardVendorID = 0;
		ULONG cardProductID = 0;
		ULONG cardSubVendorID = 0;
		ULONG cardSubProductID = 0;
		IP96->p96GetBoardDataTags(boardNum, P96BD_BoardName, (ULONG)&boardName, 
				P96BD_PCIProductID, (ULONG)&cardProductID,
				P96BD_PCIVendorID, (ULONG)&cardVendorID,
				P96BD_BoardDriver, (ULONG)&boardDriverName, 
				P96BD_ChipDriver, (ULONG)&chipDriverName, 
				P96BD_InternalMemorySize, (ULONG)&totalInternalMemory, TAG_DONE);
 
		if(!boardName)
		{
			boardName = "Unknown";   
		}

THe code above extracts more than you're looking for, but I figure that it might be useful for someone else.

@Hans Retrieving the screen

@Hans

Retrieving the screen mode name should definitively help me and also this should include the monitor name.

Thanks for the helpful and handy responses, as usual.

@Hans I actually solved the

@Hans

I actually solved the problem using
IGraphics->GetDisplayInfoData( ..., struct NameInfo, DTAG_NAME, ... )
which allows to get a string like for example "Radeon 9250:800x600 ARGB32".
