As a conclusion and just for fun, my properly working spectrum-like system.Make 1680x1050 and 1440x900 resolution available on Intel 8285282855 GMGME Chipset.
Syncmaster 2243 Lnx Drivers Were InstalledAfter installing fresh MS Windows copy using the 226cw connected through VGA (CRT) port (actually it was only way I found to set output to external monitor as default option for normally staring Windows), I was realized what there is no way to set native 1680x1050 resolution for 226cw even after latest SyncMaster drivers were installed.
There was no problem to figure out what the trouble is in the graphical chipset which is Intel 8285282855 GMGME. Syncmaster 2243 Lnx How To Overcome ThisBut it was unclear how to overcome this and is it possible at all. Intel has this problem solved only in more new chipsets no straight way to fix. And by the way the problem was almost solved, but almost only. There was still one unknown artifact, so called Modeline or DTD from 226cw. So now I can describe how to force 852855 chipset to work properly with your monitors native resolution. Getting things done First of all go to the Intel Download Center, type IEGD into the search window, choose the chipset you have (852855 in my case): and then OS System. Press New DTD. Now you supposed to enter specific technical parameters of the monitor you a going to use. Here I provide you with DTD for 1680x1050 and 1440x900 resolutions for 226cw. You can google it using your monitors model name and Modeline word. The common Modeline looks like this: Modeline 1440x90060.00 106.47 1440 1520 1672 1904 900 901 904 932 -HSync Vsync. I guess you are really dont care what does other numbers mean, so I just show you how transfer Modeline values to DTD: Then you have DTD parameters, you are ready to fill the New DTD form in IEGD. Here is filled DTD for 1680x1050 on 226cw: and 1440x900 on 226cw: DTDs are prepared, you a ready to proceed with New Configuration now. Enter the Configuration File Name and select your Platform Chipset, disable the Display Detection. If you are going to use the external monitor as secondary one, your option is Dual Independent Head. The Port Order in this case is LVDS (1st, corresponds to laptops display) and CRT (2nd, it is for external monitor connected through VGA port). Syncmaster 2243 Lnx Free To ExperimentIn case you connect monitor using DVI, then instead of CRT take one DVO, not sure which one, you are free to experiment). Anyway if you are to use two monitors, the main one should have its port at the first line in Port Order. I was forced to use the same CRT as main and only monitor in my system, so my configurations were: Click next. Check both Use user-defined DTDs boxes, type Readable Port Name (the name itself has no matter), for each monitor select both DTDs, DVO Device and mark Native DTD Flag. Proceed with New Package: Generate Installation: The further process is clear with no comments: You may have more than one display adapter listed, update all (obviously two) Intel chipset display adapters as shown below: After restart go to Display Properties (through right click on desktop, then Properties) and set external screen resolution to its native: Postscript I am not pretending to be the first person who has found this solution and described it. I just want to make it easier for ordinary user to understand, because I know how frustrating it is when your new monitor is able to show only blur text and stretched images.
