Read & show resolution and frequency of the screen.

[FCB38]

Hello,

I want to know the frequency and the resolution of my screen using EventGhost. I just want to press a key and see an message via the OSD.
Some body know how I can do this? I don't find a function in EventGhost.

Can you help me please?

Regards.

Hello,

Nobody can help me?
Actually it's to choose the good parameters to see my movie via XBMC :

• Bluray => 72Hz
• DVD Pal => 50Hz
• DVD NTSC => 60Hz

Perhaps there a solution to do this automatically but for the moment I think it's easier to choose the good fr├®quency manually.

Regards.

Decompress the EG_DB_site-packages.zip from viewtopic.php?f=2&t=4005#p23194 to your sitepackages directory. (C:\Eventghost\lib26\site-packages\) then restart EG. Once this is done, create a python script with below. You can then just feed the variables to the screen anyway you want. I just print them to give you an example.

Hope that helps!

Code: Select all

import wmi
d = wmi.WMI ()
for s in d.Win32_DisplayConfiguration ():
    # If you want to see everything uncomment below
    # print s
    eg.globals.displaywidth = s.PelsWidth
    eg.globals.displayheight = s.PelsHeight
    eg.globals.displayfrq = s.DisplayFrequency
    eg.globals.displaypix = s.LogPixels
    eg.globals.displaybit = s.BitsPerPel
    eg.globals.displayname = s.Caption

print "Device: ",eg.globals.displayname
print "Resolution: ",eg.globals.displaywidth, "x", eg.globals.displayheight
print "Frequency: ",eg.globals.displayfrq
print "Pixel Density: ",eg.globals.displaypix
print "Color Depth: ",eg.globals.displaybit,"bit"

There is an option in XBMC for this here, it's called "Adjust display refresh rate to match video".

Hello,

Thank you Eatmeimadanish & Jonib.
I've seen before the option in XBMC in the past but I forgot it. I will try.
I will try the solution of Eatmeimadanish. It can be useful to know if the screen really change his frequency.

Regards.

OK, I decompress the file "EG_DB_site-packages.zip" in my folder (C:\Logiciels\Utilitaires\EventGhost\lib26\site-packages).
I create the new python script at the begining of my XML file:

Code: Select all

    import wmi
    d = wmi.WMI ()
    for s in d.Win32_DisplayConfiguration ():
        # If you want to see everything uncomment below
        # print s
        eg.globals.displaywidth = s.PelsWidth
        eg.globals.displayheight = s.PelsHeight
        eg.globals.displayfrq = s.DisplayFrequency
        eg.globals.displaypix = s.LogPixels
        eg.globals.displaybit = s.BitsPerPel
        eg.globals.displayname = s.Caption

    print "Device: ",eg.globals.displayname
    print "Resolution: ",eg.globals.displaywidth, "x", eg.globals.displayheight
    print "Frequency: ",eg.globals.displayfrq
    print "Pixel Density: ",eg.globals.displaypix
    print "Color Depth: ",eg.globals.displaybit,"bit"

Now I can read this in the log file:

Code: Select all

   Device:  NVIDIA GeForce 8600 GT 
   Resolution:  1024 x 768
   Frequency:  60
   Pixel Density:  96
   Color Depth:  32 bit

How can I read this and put it in an OSD message?

Thank you for your help!

How can I read this and put it in an OSD message?

Putting this in the ShowOSD {eg.globals.displaywidth} should show the displaywidth, just change it to one of the other eg.globals. for other data.

It' me again. I've got a problem. I execute the script to show me information in the log file. But If I change resolution (after EventGhost starts), the script doesn't see the new values.
What's wrong? How can I repare it?

Can you help me?

Thank you.

Your command Jonib is functionning perfectly. Thank you for this.

I always got my problem of reading values for frequencies and r├®solution. The script given by eatmeimadanish seen to return always the same values.
I don't know where I have too put the script. For the moment I put it at the begening of my configuration tree with an other one:

Code: Select all

#Script "Minimize XBMC"
from win32gui import FindWindow, GetWindowPlacement
try:
    if (GetWindowPlacement(FindWindow('XBMC','XBMC'))[1] == 2):
        eg.result = True
    else:
        eg.result = False
except:
    pass

#Script "Read screen's state"
    import wmi
    d = wmi.WMI ()
    for s in d.Win32_DisplayConfiguration ():
        # If you want to see everything uncomment below
        # print s
        eg.globals.displaywidth = s.PelsWidth
        eg.globals.displayheight = s.PelsHeight
        eg.globals.displayfrq = s.DisplayFrequency
        eg.globals.displaypix = s.LogPixels
        eg.globals.displaybit = s.BitsPerPel
        eg.globals.displayname = s.Caption

    print "Device: ",eg.globals.displayname
    print "Resolution: ",eg.globals.displaywidth, "x", eg.globals.displayheight
    print "Frequency: ",eg.globals.displayfrq
    print "Pixel Density: ",eg.globals.displaypix
    print "Color Depth: ",eg.globals.displaybit,"bit"

One more time I need your help. THANK YOU!

Code: Select all

import wmi
d = wmi.WMI ()
for s in d.Win32_VideoController ():
    # If you want to see everything uncomment below
    # print s
    eg.globals.displaywidth = s.CurentHorizontalResolution
    eg.globals.displayheight = s.CurrentVerticalResolution
    eg.globals.displayfrq = s.CurrentRefreshRate
    eg.globals.displaybit = s.CurrentBitsPerPixel
    eg.globals.displayname = s.Name

print "Device: ",eg.globals.displayname
print "Resolution: ",eg.globals.displaywidth, "x", eg.globals.displayheight
print "Frequency: ",eg.globals.displayfrq
print "Color Depth: ",eg.globals.displaybit,"bit"

You could try the video controller WMI lookup

Hello,

It's me. I try you solution and I'm sorry but it doesn't work.
In attached you can find 2 files:

• First

  2012-10-10 - XBMC.xml

  (27.9 KiB) Downloaded 181 times

  give no error but the returned resolution and frequency are alwayys the same.
• Second

  2012-10-19 - XBMC.xml

  (27.63 KiB) Downloaded 278 times

  give errors and return nothing:

---> Welcome to EventGhost <---

It seems to be hard, I don't understand what I do, but if you can help me I'll be happy.

Thank you and regards.

[eatmeimadanish]

That error is when a value is empty. Just declare the variables at the top of the script, and give them empty values. This should resolve that issue.

Like:

eg.globals.displaywidth = "NA"
eg.globals.displayheight = "NA"
eg.globals.displayfrq = "NA"
eg.globals.displaybit = "NA"
eg.globals.displayname = "NA"

Hello,

I have no more errors but the returned values are always the same. I change resolution and the values don't change.

If you don't understand let it fall.
Thank you very much for your help.

PS : I put the new configuration file.

Hello,

I find what's wrong. In fact I was using "Win32_DisplayConfiguration" instead of "Win32_VideoController".
I can read the good values now.

Thank you and see you later.
