Hi all, any help out there?? First some details; I have 64-bit Ubuntu 11.10 installed from a LiveCD and am having problems getting the resolution I know the hardware is capable of. GFX card: $ lspci grep VGA 01:00.0 VGA compatible controller: nVidia Corporation GF110 [GeForce GTX 580] (rev a1) My monitor is an LG Flatron W2243S, which unfortunately doesn't seem to have a Linux driver. Fisher rs 717 manual pdf. I know it supports up to 1920x1080, but via the 'Displays.'

GUI I can only select 1024x768. Yet more information! Strangely I had to hack my way into Ubuntu via 'nomodeset' - I suspect this is to do with an nVidia driver problem, and since then I've installed the nVidia driver. OK, so progress. Seems the NVIDIA driver doesn't get the EDID info.

From /var/log/Xorg.0.log: [ 6.757] (WW) NVIDIA(GPU-0): The EDID read for display device CRT-0 is invalid: [ 6.757] (WW) NVIDIA(GPU-0): unrecognized EDID Header. Welcome to the forums. It looks that your display has a corrupt EDID. Since I was 'blessed' with a laptop with a similar problem, I've learned a few tricks that can help you. I can't promise you that they will work, but I would gladly help you as much as I can. My first idea would be to try to use another input. Sometimes there are more chances of retrieving the EDID data from a DVI, or HDMI input.

Check this as a point of reference. If that don't work, we need to get the correct EDID data. There is a reasonable chance that other people had faced the same problem, and may be you can find in the web a downloadable fixed EDID file that we can 'hardcode' into xorg.conf The last resort would be to try to fix it ourselves.

I would gladly help you with that if it comes to it. This is an example of the work the would need to be done:. I hope those references point you in the right direction, and tell us if you need more help with this. Thanks Papibe! I think you hit the nail on the head, but unfortunately I'm not at a solution just yet.

In fact, I was looking at the possible effects of different inputs - this monitor ships with an SVGA output, which I'm having to use an adaptor to plug into the DVI port. Short of buying a new monitor, I'm not going to be able to switch that.

So, I spotted your useful tip on (dare I say it) using my Windows OS to get hold of the EDID file. Phoenix EDID Designer, installed and used. Interestingly there are two EDIDs on there: IV46BA is an Iiyama EDID.

HSD899A appears to be just a generic one, but also no fail on CRC.
