BringerOdeath Posted September 23, 2016 Share Posted September 23, 2016 Hello Everybody, I have a GT72 6QD that came with a GTX 970M and I swapped in an alienware M18 GTX 980m 8GB, but nothing comes up on the laptop screen. It does display video through the HDMI port to a tv or monitor. I updated the nvidia driver and now nothing comes up through HDMI or the laptop screen. I can tell it's booting since the caps lock keys and other F keys work, I just have nothing on the screen. Would this be related to the Alienware GTX 980 Vbios?

Bloetschkopf Posted September 23, 2016 Share Posted September 23, 2016 First You can try MSI Vbios for GTX 980M. Your GT72 have G-Sync or not? Quote Link to comment Share on other sites More sharing options...
BringerOdeath Posted September 23, 2016 Author Share Posted September 23, 2016 It does have G-sync. Is there a specific bios that it has to have because of G-sync? I put the 970m and the 980m in a 2 year old sager that had an 870 m and boards work perfect on that laptop. I am leaning towards the card bios or the motherboard bios.... Is there an msi G-sync gtx 980m bios I can flash on the card? Quote Link to comment Share on other sites More sharing options...
Bloetschkopf Posted September 23, 2016 Share Posted September 23, 2016 (edited) If the Card have G-Sync You must flash a G-Sync Vbios. Edited September 23, 2016 by Bloetschkopf Quote Link to comment Share on other sites More sharing options...
BringerOdeath Posted September 23, 2016 Author Share Posted September 23, 2016 I don't think think the alienware m18 GTX 980m has a G-sync enabled bios. I think this would be why the screen is blank while still outputting to a TV or monitor through the HDMI port. Can a G-sync bios be flashed onto a a gtx 980m that was not originally for G-sync?

No. There are slight board changes (An added resistor) and a new hardware ID. Cross flashing will brick the GPU. Quote Link to comment Share on other sites More sharing options...
BringerOdeath Posted September 24, 2016 Author Share Posted September 24, 2016 (edited) Is it related to gsync, why the screen wont display anything? Is it that the non gsync card wont work when the screen has gsync enabled Edited September 24, 2016 by BringerOdeath Quote Link to comment Share on other sites More sharing options...
BringerOdeath Posted September 24, 2016 Author Share Posted September 24, 2016 I put the G-sync GTX 970m back in the laptop and it works just fine and the screen is visible. Would there be something the lcd panel itself that hs to have a Gsync card installed for it to display anything? Quote Link to comment Share on other sites More sharing options...
BringerOdeath Posted September 27, 2016 Author Share Posted September 27, 2016 Can someone answer this question?! If the laptop is a gsync laptop and I replace the gsync video card with a non gsync card, would that cause the screen to have no image? Does the monitor have a Gsync chip in it that requires a gsync card to even display and image on the internal monitor? Since I replaced the gtx 970m gsync with a gtx 980m non gsync, would this be causing the issue? Quote Link to comment Share on other sites More sharing options...
Bloetschkopf Posted September 28, 2016 Share Posted September 28, 2016 Please flash first the MSI Vbios of the Card,after this You will see it work or not. Quote Link to comment Share on other sites More sharing options...
