I just looked through the Windows 7 driver list and there is no E228WFP. If your monitor is not in the Drivers for Microsoft Windows 7 drop down list, there will not be one. Windows 7 will load its generic PNP driver for the monitor.

its really unfortunate that Dell doesnt choose to update a driver for this relatively new monitor. I will definitely look elsewhere the next time I need a monitor.

I got it to work.

I have a dell e228wfp that I used on a new custom built PC.  I understand why dell wouldn't support legacy peripherals... they want you to spend money.  Bad ethics, good business. Anyways, I'm guessing they're not going to tell you that you can get it to work somehow.  Hopefully this doesn't get erased, so it can help others.
------------

Before starting, go ahead and go to dell's support page and download the XP drivers for the monitor.

1) Windows Key + Pause gets you to System Properties > go to Hardware Device Manager, look for monitors on the list of devices on your PC, expand it and it'll probably say something like a Generic VGA something or other.

2) Right click that > Update Driver > Search somewhere on my computer > !! "Don't search, I will choose the driver to install" > Have disk > locate the XP driver you downloaded > install.

3) It should work, nothing will happen.

4) Reboot.  Now the Monitor should show at 1680 x whatever.

I updated my computer to Windows 7 Professional 64 bit that has a E228WFP monitor and a Galaxy GT 220 PCIe video card.  I went to Dell's monitor drivers web site and downloaded the Vista 64 bit driver for the E228WFP as Win 7 did not list the E228WFP monitor.  The driver came in a zip file and I had to unzip it and move the files into a new folder in order for shin_tre instructions to work.  I followed shin_tre instructions and after rebooting I was able to set screen resolution to 1680 x 1050, the highest I have ever gotten on my 2 year old monitor.

Glad I could help!

WOW! AND THANKS! THIS WORKED FOR ME AND SAVED ME ABOUT $400 ON MY DUAL MONITOR SYSTEM!

I upgraded to Win7 PRO 64 Bit with a new GeForce GTX 560 Ti (1024MB,256-BIT) Video card and for the life of me could not get Windows 7 to recognize max resolution on either monitor... so i googled the issue of "DELL E228WFP Not Recognizing Max Resolution on Win 7 pro 64bit" for about a day and a half when low and behold i found this post on getting DELL E228WFP Monitors to recognize Max Resolution of 1680 x 1050. I almost had to buy 2 new monitors but this post bought me some time and SUPPORT would not tell me the secret. DELL PLEASE DO NOT ERASE THIS POST IF YOU VALUE CUSTOMER SATISFACTION.

I followed your instructions exactly and WOW... IT WORKED!!!!

THANK YOU! Now i can save the money for my kids.

I can't seem to find ANY of the drivers for the 228WFP on the Dell site anymore.  Any chance one of you saved it off and has it handy and could email it to me or something?

Thanks in advance!

I found a list of monitor drivers here: http://ftp.dell.com/monitors/.  R144815.zip and R137889.zip both apply to E228WFP monitor but neither would let me set it to 1680 x 1050.  Is there a list somewhere that shows which drivers at the ftp site apply to which monitors?  Many of the files give no clue as to which monitors they support.

fcambel,

No, the FTP site does not have such a listing. What operating system are you running? Is the video card driver loaded and does the video card appear in the Device Manager?

I tried the Dell PC Diagnostics web utility and after granting all permissions it does't even recognize the existence of the E228WFP monitor.
