Hello Guys this is my first post here!
So my original post was this:
"I don't even know if any active forum is out there on this laptop and on this issue, but after installing my new DHCG2 LTN173HT02 120hz display, I am unable to boot up on it. I do have a modded bios which the video setting is set to PEG, and just about read every forum about this but have not found a solution. I have tried resetting the bios, made sure the cable is plugged into the Edp port, and have made sure I have an UFEI Windows installation and legacy mode is turned off. I don't know what else to do and if anyone could help it would mean alot to me! "
The reason it was not booting up on a pure UEFI environment is because my 660m did not have the GOP compliant driver vbios. You would need this in order to boot up in a pure UEFI environment which at the time I didn't know, and my fix was to stick to legacy. Any card before the 660m will most likely require this if you need to boot up in a pure UEFI environment. If you do not have this vbios driver while it is set to UEFI and plug in the 120hz lcd, it will beep 8 times and you will be forced to plug back in the 60hz display to change it back to legacy.
This was the vbios that I can say worked for me and had the GOP compliant driver for the 660m
These are the steps to upgrade from a normal 1600x900 60hz display to a 1920x1080 3D 120hz Display which is needed if you want to update your graphics card to a more modern one.
I am making this guide because I felt frustrated that for this awesome computer, there aren't really any post in 2020 to upgrade the LCD panel to the 3D 120hz one. And The older posts I scavaged through really helped me little in doing this upgrade.
Anyways lets begin
1) If you have a stock AMD graphics card, and are wanting to install the 120hz display, then your journey ends here and you will have to upgrade to an NVIDIA graphics card to do so. If you have an NVIDIA, you may continue
1a) ( Only if upgrading to pascal graphics card )Your NVIDIA card Needs to have a GOP compliant vbios or else it will not let you select the UEFI option on the bios. This is needed because you need to set a UEFI environment before upgrading to a 1060/1070 Since these cards don't support legacy mode. This means you will need to flash a vbios onto your card that will allow you to boot on a UEFI Environment. You will need to verify first wether your card has a GOP compliant vbios by searching up your vbios version in GPU-Z. If you have a 660m that doesn't have this, then here is the link to that vbios that does. https://www.techpowerup.com/vgabios/144032/144032 I think that all of the Nvida 6XXm are not GOP driver compliant and need this but do not quote me.
2) On the 60hz display, I would start by making sure that you have windows 10 installed or reinstall with UEFI support as it is needed if you are installing a pascal graphics card. If you have legacy mode enabled, and are not planning to upgrade to a pascal graphics card and keeping your old Nvidia 6XXM, then disregard this and head on to step 5 (although I would recommend to read everything)
3) turn the laptop off and boot into the bios. In order to boot into the bios, spam the F2 key while it is turning on.
4) Once in the bios, go to the Boot menu, and make sure to Disable "Secure Boot", Make sure that importantly if you converted over to a UEFI installation of windows, UEFI mode is chosen (UEFI Environment will be needed for a pascal graphic card and legacy will not be compatible) then again, if you are on a legacy installation of windows 10, disregard this if you don't want to upgrade to a pascal graphics card.
5) we can now start looking at the 120hz display. I bought mine on ebay with this seller https://www.ebay.com/itm/New-Dell-Alienware-M17X-R4-17-3-FHD-WLED-3D-V-M-LCD-Screen-DP-N-DHCG2-GN36T/273644412867?hash=item3fb67a5fc3:g:9A0AAOSw5AhcP1pw:sc:USPSPriority!32720!US!-1 (Just in case the link goes bad, this was the listing name"Alienware M17X R4 17.3" FHD WLED 3D V M LCD Screen DP/N DHCG2 GN36T" with the screen model being LTN173HT02 and Dell part number GN36T )
6) Since my listing came with the video cables, I did not have to go out and look for the video cable. If yours did not come with the cables, You will also NEED to get the video cable it is required. the Dell Part number is N392W. I cannot stress enough This video cable is required and the 60hz's video cable CANNOT be used with the 120hz one or else you will brick your computer from what I read.
7) Once it comes In, we can start to take apart the computer to Install our new display. I watched this video to remove the old 60hz and install the 120hz panel
8) Before I would remove the whole 60hz lcd panel, I would first make sure that you can boot on the 120hz panel. Notice that there is one connecter with screws on both sides right next to where the 60hz screen connecter is. Make sure that you put the 120hz one with the connector where screws are. This is known as the Edp port and cannot be confused with the LVDS port. Again, you want to plug the new 120hz display into the EDP port and unplug the 60hz one.
9) If the installation was done correctly, then you should have no problem booting with the screen. if it is giving you 8 beeps, then just plug in the 60hz display, and navigate back to the bios to make sure everything is in order and refer back to steps 2-3. If you happen to be an advanced user like me and went ahead and installed a modded bios, then on the 60hz display make sure that the video setting is set to PEG. I dont think this is necessary to have a modded bios since the bios automatically changes the video setting when the 120hz display is detected and should be a last resort option to install a modded bios. I got my modded A12 bios from a guy in this forum named klem for 10 US dollars thorough paypal. Shoot him a message in the forum below.
10) Once the new LCD is tested and you know you can boot up with no problems, go ahead and finish removing the old 60hz LCD and proceed to finish installing the 120hz LCD. And you are done.
A couple of words from my personal experience: When I installed the 120hz display, and booted up windows on it, and turned the computer off, it refused to turn on for some weird reason. I don't know why it would turn on when the AC and battery where on. regardless of what this was, I fixed it by Reseting the CMOS. If you don't know how to do this, do a quick google search and after turning it on i got 5 beeps which i then turned the computer off, and then turned it back on which the computer just reset itself and when it turned back on I was able to boot up into windows.
This is the forum that I was able to find about upgrading the graphics card to the 1060.
Anyways I hope I at least helped someone transform their computer! In 2020!
Hello, I've got a Dell Precision M4700 with a 3940xm. I've read that in this particular CPU and laptop model, the bios is locked because the stock settings are considered an overclock. As-is, the core temps on the CPU do reach up to 90-100. They seem to spike up and down a bit when benchmarked with Intel's Extreme Tuning Utility, but they certainly do reach over 90C. Is there no way to unlock this bios (version a18, though a19 is released - I haven't updated yet, should I?) and even if there were, would my only option be a heatsink mod on top of that?
edit: I've mistakenly posted this under Desktop & General Hardware, perhaps a mod could move or delete the thread? Apologies!
Hello, I've got a Quadro M2200 (GPU: GM206GL-A Revision A1, and MxM 3.0a Maxwell card) with the following bios: 84.06.76.00.1C
I've read that this card is very similar to the GTX 965m, but that it has been underclocked considerably. It seems to be a good candidate for unlocking since I hardly see the temperature exceed 70C as-is. I'm requesting help with this - I'm not sure if it's possible to simply flash the vbios from a Dell GTX 965m (MxM 3.0a) or if some type of edit of the card's current vbios would do the trick. I'm hoping someone could help me out with the specifics of doing such an edit if that's the case.
I am an owner of MSI GT70-20C and my GTX770m gpu i now dead.
I have a question and i hope someone will help.
I have ordered GTX 970m 6GB DDR5 and i cannot find the exact vBios for that graphic card.
My current bios version is: E1763IMS.51B
Thanks in advance,
I own an Asus Fx504-gm laptop with an 8th gen i7 and nvidia gtx 1060. I ve been having issues with random hard freezes and I later found out that absolutely anyone with this exact model has the same issue and not even Asus service can fix it as they just replace every component and the problem persists so my guess is that this is software related.
I ve been noticing that I Always hit power limit(I monitorised it with afterburner) and so I have power limit throttling. The thing is, for this laptop the power limit is locked and I cannot modify it.
My last resort is to try a modified bios that can unlock the power limit slider. My question is: Is this possible? Are there any modified bioses that can unlock the power limit or the only way is to unlock it via the motherboard? If so, where can I get a reliable modified bios for my laptop and how can I check compatibility? Thx.
