Guest Blahman Posted October 14, 2007 Report Share Posted October 14, 2007 This is for Westinghouse LVM-37w3se owners with the wrong EDID (recognized as W4207 or WDE4207). This is basically a repost from HardForums and AVSForums, so there may be some redundancies. I've been testing another way to get 1080p out of NVIDIA cards for those of us stuck with a bugged EDID. It's not perfect (shifts the screen left 5 px, 1366x768 still default resolution on first detection) but other than that it works well for me. It involves modding the nv4_disp.inf (OR equivalent OEM-named INF file, e.g. NVDM.inf for DELL mobile drivers) in the driver installation package and reinstalling the drivers. Here's how: Download Driver Cleaner PE or Driver Sweeper if you don't already have one of these cleaners Download and run the installer for the drivers you want to install, extract them to a location you can remember (anywhere but the default C:\NVIDIA, because Driver Cleaner PE will erase that folder), but instead of installing them straight away, cancel out, and open the folder you extracted them to. If using LaptopVideo2Go drivers download and copy Pieter's modded INF into the folder, overwriting the original INF. Open the INF file with notepad Search for the section labeled [nv_SoftwareDeviceSettings] Look for a series of lines starting with HKR,, NV_R&T, Select all of those lines and replace with: HKR,, NV_R&T,[tab][/tab][tab][/tab][tab][/tab][tab][/tab] %REG_MULTI_SZ%, "R&T0000=1920,1080,*,60,*,WDE4207,OEM,14850,2200,72,44,1125,4,5,++" What this does is it tells the NVIDIA drivers to look for a monitor called "WDE4207" (as reported by the faulty EDID), and gives it a timing for 1080p. Uninstall current drivers. Reboot into safe mode. Run Driver Cleaner PE or Driver Sweeper Locate the folder you extracted the new drivers to and run setup.exe and install the drivers. Reboot. After Windows boots up, set the Westy as your primary monitor and change resolution to 1920x1080. If all went well it should be running in 1080p. Let me know if anyone tries this and their results. I'm also looking into another similar INF mod that overrides the faulty EDID data with correct EDID data, which would potentially be a much nicer fix. But I need help. I need one of you with one of the new SE's WITHOUT the bugged W4207 EDID to download and install softMCCS, and do the following: Install and run softMCCS From the yellow drop down box make sure your Westinghouse monitor is selected Do File-Save EDID As... Change the "Save as type" box to "ASCII text file (*.txt) Save the file somewhere and open it with Notepad Copy and paste the contents of the file and post it here on the forums. Wrap in CODE tags for proper formatting. e.g. (my buggy "W4207" EDID data)00FFFFFFFFFFFF005C85074200000000 16100103805D34782A3130A256499C25 10484BA1080081C0810081808BC00101 0101010101019D1C5692500028303020 3500A20B3200001A000000FD003B481E 440F000A202020202020000000FC0057 657374696E67686F75736520000000FC 0057343230370A20202020202020018C Referencing this thread and this thread at LaptopVideo2Go.com, it should be possible to have the drivers override the faulty EDID with the proper EDID by adding a line to nv4_disp.inf. I need to figure out how to convert "WDE4207" to bytes (four bytes to be exact) as in the above threads. Any clues? I should probably be able to figure it out but its been a while since I took my comp sci classes. :o Quote Link to comment Share on other sites More sharing options...
