inf 56.54

[®®®]

hi, just had my quick first look on 56.54 (TS) inf.

What i found out is that the nvsysrot.dll is responsible for the Rotation feature and some systray icon i think. I had not the possibility to test it thoroughly, if there is a icon in the systray or not or how it looks like or if there are bugs or issues (to much other things to do in the last days). I mean it's not THE important feature, but good to know what the nvsysrot.dll is good for...

It's easy to tell, because of this setting in the inf

[RotateSysTray_AddReg]

HKLM,SOFTWARE\Microsoft\Windows\CurrentVersion\Run,"NVRotateSysTray",,"rundll32.exe %11%\nvsysrot.dll,Enable"

Another thing i noticed is the "OverrideEDIDFlags0" setting for exclusively NV34_LSR (DEV0328.3). I still have no clue what the EDID exactly is and why it only is "overrided" for the device 0328.3. I know it's some manufacturer information integrated in the panels/LCDs, but...

Then we have a new "BroadcastDisable"=YES setting for ALL GPU models. I wonder what type of "Broadcasting" has to be disabled, so that all mobile GPUs are working correctly and why it has to explicitely implemented in the new (mobile) 5x.xx series (this setting does not exist in 56.55/53.03/53.04/53.06)?

The same with "MutuallyExDevs" for ALL GPU models under SoftwareDeviceSettings.

Things to think about and implement (maybe) in future infs ????????

Interesting! The Dell version doesn't use, or seem to need, any of those four settings. But it does include some other new settings including (if I remember correctly), DrvOptions, ResetPolicy, CopyKeys, MediaCenterLoadPolicy, and ControlsOverride. It also had several new values for some of the older settings.

I may play with some of those Tosh settings to see if they have any effect on my Dell.

I have also been pulling apart the drivers, but at a more basic level.

I've discovered more enables, disables and some other features (that don't do anything on a GF2g, but might do things higher up the food chain)

I'll post my findings later.

Good work guys, with all our different interests in how drivers work, we should be able to get a good database of what does what.

EDID = Extended Display Identification Data

"VESA, as the prominent standards organization for graphic sub-systems, has developed the EDID data format as a compact method to specify the capabilities of various types of monitors as well as integrated displays."

Basically, built in data to tell you what the monitor can handle.

[Guest Guest]

ok, basically the EDID tells the OS or driver what (for example) refresh rates, resolution, polarisation or even size the panel/LCD supports??? My or our problem is that we can't "read" those values, because there are some weird numbers when i look into the registry

[Teraphy]

For the most part yes. The EDID will do those things. Issue one being the EDID can't always be read because it's not always supplied -- laptop LCD's for example don't seem to have one while all CRT monitors do. Second not all the information in the EDID needs to be specified. To be honest I don't know which is needed.

When properly read you'll get the manufacturer or type of monitor. When not found NVIDIA drivers have to makeup or read the data stored in the BIOS for EDID info. The madeup data will have info such as:

                   EDID Version # 1,  Revision # 3
             DDCTest For: NVD Nvidia Default Flat Panel

This is the one for my 19" Dell CRT (P991)

The data at the top is the EDID info found in the registry.

                   EDID Version # 1,  Revision # 2
                     DDCTest For: DEL DELL P991

That IS interesting alright...
