HP 2509m HDMI image to big for screen

[gslabbert5119]

I have a new HP2509m  monitor connected to a hp DV6T notebook via HDMI and the image is too large for the screen. It seems that the image overlaps the monitor by about 3/4" on all sides. When I connect the monitor to the notebook using the VGA cable the image is sized correctly.

There appears to be no way to resize the image while using the HDMI connection (auto-sense I guess). I can make the image fit if I use an image smaller than the factory recommended 1920 x 1080 but that is not what I purchased.

Monitor is connected as external monitor and the notebook is closed, and the notebook screen is disabled so I am only using 1 screen and there is no conflict that I am aware of between the internal screen and the external screen. No dual screens here.

All settings are factory and are 1920 x 1080. 60 hertz.

Spend 4 hours online chatting with tech support to no avail.

All drivers are up to date, we checked and rechecked them, we replaced the monitor with a Dell 24" and connected that via HDMI and it sized correctly, we replaced the HDMI cable and that made no difference to the 2509m.

If you have an ATI card (with the latest updated drivers)....

Right click desktop...

Left click Catalist Control Center should bring up Monitor Properties...

Left click adjustments

adjust

The notebook has an intel chipset and no ati video adapter in it.

I found this...I'm not sure what it means, and if it's applicable to you but it makes for interesting reading...and of course I wouldn't recommend any modification without consulting an expert...which I am NOT....

Manual modesetting for xf86-video-intel

The new x86-video-intel-2.0.0 driver (known in Gentoo as xf86-video-i810-2.0.0) does automatic modesetting: instead of relying on the video BIOS for a list of resolutions your laptop’s screen supports (which is always the wrong list on modern machines), the new driver reads the information directly from the monitor using DDC over i2c. Which is in theory better - unless, of course, your monitor lists the wrong resolution in its DDC.

My Dell Inspiron 6000’s flat panel’s DDC happens to list the following resolutions: 1920×1200, 1024×768, 800×600, and 640×480. The latter three do not match the screen’s 16:10 aspect ratio, so there is no good reason for them to be in the list. On the other hand, the list doesn’t contain 1680×1050 and 1280×800 (which are 16:10 resolutions that enable one to achieve better framerates on one’s puny Intel 915GM graphics card). With the old non-modesetting driver, one could use 915resolution to hack the video BIOS and write in custom resolutions. Unfortunately, there is, AFAIK, know way to modify a monitor’s DDC. Furthermore, the draditional xfree86 and xorg method of setting resolutions (Section "Screen" -> SubSection "Display" -> Modes "1680x1050" "1280x800" etc) no longer has any effect, probably thanks to the randr-1.2 black magic in xorg-server-1.3. So what is an Inspiron 6000 owner supposed to do?

By reading the past few months of the xorg@fdo mailing list and extrapolating from the information therein, I have arrived at a workable solution. Edit your xorg.conf to look something like:

Section "Monitor"
        Identifier   "Dell LFP"
        Option       "DPMS"
        HorizSync    31.5-100
        VertRefresh  58-61
        DisplaySize  331 207
        Modeline     "1920x1200" 162.00 1920 2020 2108 2160  1200 1201 1204 1250 -hsync +vsync
        Modeline     "1680x1050" 149.00 1680 1760 1944 2280  1050 1050 1052 1089 -hsync +vsync
        Modeline     "1280x800"  83.46  1280 1344 1480 1680  800 801 804 828 -hsync +vsync
        Modeline     "1024x640"  52.83  1024 1072 1176 1328  640 641 644 663 -hsync +vsync
        Modeline     "800x500"   31.33  800 824 904 1008     500 501 504 518 -hsync +vsync
        Modeline     "1024x768"  65.00  1024 1048 1184 1344  768 771 777 806 -hsync +vsync
        Modeline     "800x600"   40.00  800 840 968 1056     600 601 605 628 -hsync +vsync
        Modeline     "640x480"   25.20  640 656 752 800      480 490 492 525 -hsync +vsync
        Option       "PreferredMode" "1680x1050"
EndSection

Section "Device"
        Identifier  "Intel 915GM"
        Driver      "intel"
        BusID       "PCI:0:2:0"
        Option      "DRI" "true"
        Option      "XVideo" "true"
        VideoRam    131072
        Option      "XAANoOffscreenPixmaps" "true"
        Option      "Monitor-LVDS" "Dell LFP"
EndSection

The first key point is Option "Monitor-LVDS" "Dell LFP". Without this option, the Intel driver will override any custom resolution you may have defined. You need to use "Monitor-LVDS" for your laptop’s built-in screen and "Monitor-VGA" for external VGA output. For external DVI output, it’s either "Monitor-DVI" or perhaps "Monitor-TMDS-1". Naturally, the Monitor-* option is not documented anywhere.

The second key point is Option "PreferredMode" "1680x1050". This guarantees that gdm etc. starts at the resolution you want instead of at the highest one.

The third key point is VertRefresh 58-61. The problem is that your LCD screen may report that it only supports 60Hz, and although you generated 60Hz custom modelines, some of them might actually have a vertical refresh of, for example, 59.97Hz or 60.002Hz, which will cause X to complain and fill your Xorg.0.log with messages like

(II) intel(0): Not using default mode "1280x800" (vrefresh out of range)

So you need to override the 60Hz to account for rounding errors.

Oh, and to create all those custom modelines, I used the highly useful cgi script at http://www.sh.nu/nvidia/gtf.php (C version).

Now, the next task is to figure out why the new driver gives me a 30% lower framerate in glxgears…

Hi,

You might be running into an overscan issue.  This is not uncommon. However be sure that the below driver are up-to-date before making and adjustments.

HP 2509m monitor driver update.  Look over the utilities.

I had the same issue with my HP laptop and my ViewSonic 24inch monitor. Simple fix for me, go into the monitor's menu (using the physical buttons on the side of the monitor) and then 'Input Select' --> 'HDMI (PC)' instead of 'HDMI (AV)'. Hope that helps
