snagsy Posted July 9, 2017 Share Posted July 9, 2017 (edited) Hi guys first time posting here. I'm hoping for a little help. I have a m17xr4 quite a few years old now which has gone through a couple of GTX675m's now. So recently I purchased a GTX680m from ebay and after installing I am getting a blank screen, with no back lighting or signs of life.Fans/Lights run and I hear windows start fine, but I'm unable to switch to internal graphics after pressing the Fn F7. If I hit enter I hear an error menu so something pops a new window up. If i remove the GTX680m it displays fine with its internal hd4000 graphics. I have been speaking to the seller and found that the card is from the M17xr4 120hz wide FHD 3D. My model only has the 60hz screen but I didn't think this was a concern. With the card fitted the GTX680m warms up a little. I removed the Nvidia drivers before installation through the control panel and also DDU. I have tried Blind flashing the vbios with a stock bios sent from the original owner and also one from techpowerup with no change. I used nvflash v5.14.1 Dos version, I get 1 chime when I press 'y' 20 seconds in and get another chime 20 seconds later so I feel it has flashed but cant be 100% certain as I cant see. Any help is greatly appreciated. Many thanks.

AleksR17x Posted July 29, 2017 Share Posted July 29, 2017 Sounds to me like the 680m you got has a problem with the output. If you buy another i would buy a 770m and get a 3D screen. The 120hz refreshrate is relaxing to look at compared to 60. I wouldnt mess with stock bios to modified then go stock again. Leave it modified so you can upgrade from 680m and set Display to PEG for 3D display. Quote Link to comment Share on other sites More sharing options...
