How can I set wide screen resolution for external monitor with my thinkpad R52? I'm running Win-XP SP2.
My R52 is 1858-69G using Intel 915GM/GMS, 910GML chipset. The presentation director sometimes (no always!) show the wide screen resolution as an option but when selecting any wide screen resolution I get message 'the setting you have selected cannot be applied properly'.

The tried all the possible combination, updated to the latest version of bios, chipset drivers, presentation director version, etc. Nothing works.

Anyone has any idea? Click to expand.Does the display device you are plugging in, support DDC serial interface and provide EDID data? You can check that, by using this tool. When the monitor is connected, that utility should be able to display a page of info about the external display device.
It may list the max (native) resolution. (Mine lists 1280x1024.) The video driver needs that, to validate the max resolution. Without validation, the driver will limit resolution to a lesser (safe) value. My LCD monitor, also has a 'monitor driver' available for download. This is a 3KB.INF file, and it declares the max monitor resolution. If the DDC method was busted for whatever reason, installing the 'monitor driver' will keep the video driver for the laptop GPU, properly informed. Not all monitor makers provide a driver file, because they insists all is 'Plug and Play'.
Which is true if DDC is working, but not true if it is broken for some reason. The specs for 915GM, mention 16x9, so some modes other than the old ones should be available.

Click to expand.Well, that answers the first question. It seems your display has a full EDID. First, some display control panels have an option to 'show supported resolutions' or 'show all resolutions'. Sometimes, the less familiar resolution options are hidden.
In this article, they say: 'Normally speaking, the Intel drivers seem to provide the standard list of resolutions: 640x480, 1024x768, even some 'home theater' resolutions like 1920x1080 and 1280x720.' I'm not convinced you should have to hack the driver to get what you want. Also, when reading articles like that one, be aware that in discussions of notebook GPUs, there is driving the panel in the notebook itself, and then there is driving the external monitor. Intel goes to great pains in their documentation, to solve the first problem. So when you see an article like the above one, verify they are actually talking about the external monitor connection, and not solving an internal problem. I found the above article, as a link on this page. But this one may be describing the internal panel in the notebook, and I'm not sure about that.
I think the resolution should really be visible in the panel already. And your external monitor seems to be doing the right things. A couple more articles - none of this should be necessary: You wouldn't want to start this exercise in cloning mode, because that might restrict the available resolutions. You'd want the two displays to be independent.
I was hoping to find some pictures of the display control panel, to see what options are available. For example, one release note mentioned a 'custom resolution dialog'.
Paul, Thanks again for the help. I tried all the above options - the INF change of the driver had no effect - the new resolution never showed up in the options list. I tried creating my own driver using IEGD - followed the instruction and spent most of a day with different trials but all I manage to do is to get red and blue squares on the screen over a blank background. Then I tried PowerStrip and I managed to implement custom resolution of 1280X720. I don't' understand how exactly PowerStrip works and I wonder and there is a 'cost' in term of monitor performances to this solution? Note also that the original 915GM /GMS resolutions list doesn't include 1280X720 (I thought it does but I see now it was 1280 x 760). I wonder if this is only a driver issue or inherited property of the chipset?

Click to expand.I wasn't going to suggest PowerStrip, because in the past they didn't support chipset graphics (only ATI and Nvidia separate graphics cards had good support).
If you got it to work, there is no performance penalty. The Entechtaiwan site has a FAQ page. This is why I didn't suggest PowerStrip. For quite some time, display devices have had programmable registers for output resolution. Even the graphics card I built for my home computer in the 80's had programmable registers.
There are rules (like some have the restriction that horizontal must be divisible by 8, vertical divisible by 2), but other than that, you should be able to program them over a wide range.
Got a problem with my display/LCD panel on my IBM Thinkpad A31, approx. 3+ years old, running Windows XP.
It's a 1024x768 TFT LCD panel. It started to dim intermittently, almost a flicker, similar to when you're working on-and-off the battery, then it went dark. I checked the power and it was ok. I hit the Fn key and F7 twice and recovered the screen. It became more frequent and the recovery time gradually shortened until it went dark altogether. In case it makes a difference, when I boot up, the screen lights up for a short period of time before it goes dark.
And if I repeat the Fn/F7 cycle, the light comes on only for a second or two. I hooked up an external monitor and have been using that until I get a proper fix. Does anyone have an idea what's going on?
If yes, what do you suggest? Thanks in advance, El Viejo. I have an A31 and my backlight went out as well. Had it replaced under warranty though.
Tell me, when the screen goes dark, can you still make out the image on the screen? Perhaps in the right lighting condition you should still be able to see what's going on, even tell where you moue is etc. If the image is still there, then your backlight, or possibly some inverter board or power supply, is going bad. I've had this exact same problem on another laptop, where a full screen refresh, such as you do, brings it back for a bit. Something in there was bad. You will likely have to send it in to a repair shop. I suggest these guys: I believe you get a free diagnostic to tell you how much it will cost to fix.
We've sent probably 50 laptops to them, good work. Anyway, hope you get it fixed, but I don't think there is much you can do yourself. If it's one of those parts.
