26lx2r dvi-d problem

kamz · 16 Apr 2006 at 08:56

I received this lcd about a week ago and I have made small progress in getting dvi-d digital output. I had to use a nvidia based (geforce 2) pc via vga to dvi (analogue) to get a picture, but anything via dvi-dvi will not post.

I heard that the edid is the problem and also read topics on how people used a dvi-hdmi converters to run their pc on initial start up then swap to dvi-dvi cable.

I followed the steps listed on the forum above, I managed to get the edid from the vga – dvi connection, I then changed the edid code from analogue to digital and saved the new edid file. The file flashed fine as I now have dvi-d picture when I use dvi-dvi, even on re boots, but when the machine starts I get garbled text via the bios screen and windows loading screen, but once I get into windows the display if fine.

However when I swap to my ATI gaming machine it’s the other way round, when using dvi- dvi I get perfect bios screen and initial boot up, but when the windows logo screen finishes loading the screen shuts off and goes into power saving mode, this has happened both time in dv-dvi, or dvi-hdmi, I do not have a vga port on my ati gfx card.

Does the LG have a none issue with ATI cards, does anyone here have a LG 26lx2r running fine with either a x800, or x1800 series gfx card???

any help would be gratefully appreciated

Some early morning findings:

I uninstalled the ati drivers using my old crt monitor and placed it on one fo the dvi on my gfx card (x1800xl), and placed the LG 26LX2R on the second dvi. I used driver cleaner and got rid of all ati and CCC registry items and removed ati tray tools, i did this in safe mode and am sure i have removed all traces of ati drivers and componeents perfectly.

I then started up my PC and i now get full picture on bth screens, windows run perfectly on the lcd, but i need to get the ati drivers on.

Everytime i install cats 6.4 or cats 6.2 i end up being unable to enter windows during load up.

Anyone know a way around this issue by any chance, or any info on what i could be doing wrong???

I have tired booting the lcd with no gfx drivers and it runs fine, as soon as i install ati drivers and reboot its a no goer, i cannot get into windows at all...

I am having the exact same problem!

Please see my post here:

I think if you have another monitor, you should be able to fix it.

Good luck, I certainly need it too! I am working as hard as I can with ATI tech support but they are rather slow when it comes to replying.

it could be that horrendous tick box in ati ccc about "alternate DVI frequency" or something that could be causing this - this potentially needs to be unchecked for it to work

as stated above you will need a second screen or use a dvi to vga converter on your gfx card to get to see windows to untick said box
