nVidia released DisplayPort 1.3 & 1.4 UEFI Firmware update for Maxwell and Pascal cards

nVidia released another Driver yesterday 398.11 WHQL, yawn nothing special I can tell, the important news is that there is also an update regarding DisplayPort (DP) which is interesting because this might also bring some improvements. Like G-Sync HDR support for Maxwell & Pascal graphics cards together with a black screen fix.

nVidia DisplayPort Firmware Upgrade

Driver 398.11

You can find the release notes as usual as .PDF file here. The driver – including bloatware – is available here and my modded version is downloadable here. The Driver 398.11 is from the latest Branch r397_91-9 and dated 06/01/2018.

Here is the Changelog

Fixed Issues in this Release

  • [SLI][Hitman Pro: DirectX 12]: With SLI mode enabled, the game crashes if in-game HDR is ON and Windows HDR setting is OFF at lower resolutions.
  • [Call of Duty: WWII][Surround]: With Surround enabled, the center Surround display is blank during gameplay.

Windows 10 Open Issues

  • [SLI][GeForce GTX 1080][G-SYNC][World of Warcraft: Legion][HDR]: Severe color
    corruption appears in the game after launching with the Windows HDR setting
    enabled.
  • [Notebook][GeForce GTX 1060]: The external HDMI display blinks when playing a
    video from the Netflix Edge Browser or Blu-ray video in full-screen mode with
    Windows HDR enabled.
  • [Surround SLI][G-Sync][Overwatch]: There is constant flickering in the game when
    played in a specific SLI Surround configuration (2 displays on master GPU and 1
    display on slave GPU) with G-Sync mode enabled.
  • [Shadow Warrior 2][TITAN V]: After launching the game with Windows HDR setting
    enabled, there is flickering corruption when hovering the mouse over the game screen.
    The issue does not occur with Windows HDR setting disabled.
  • [GeForce TITAN (Kepler-based)]: The OS fails after installing the graphics card on a
    Threadripper-enabled motherboard.
  • [Pascal GPUs][Gears of War 4]: Blue-screen crash may occur while playing the game.
  • [Netflix Edge Browser]: When playing a game in full-screen mode and playing a video
    from the Netflix Edge Browser, blue-screen crash occurs after multiple [Alt+Tab]
    switching between the two.
    The issue does not occur when playing the Netflix video in a Chrome browser.
  • [Dead by Daylight]: NVIDIA Freestyle does not work with the game.
  • [NVIDIA Control Panel][Surround]: NVIDIA Surround hotkeys do not work.
  • Random DPC watchdog violation errors occur when using multiple GPUs on
    motherboards with PLX chips.
  • With HDR turned on, non-HDR full-screen video playback may cause corruption/
    flicker in the video. To avoid this scenario, disable Windows HDR setting before launching the video.

Nothing special if you ask me, why nVidia needs a Driver update for each new game is beyond me, especially because I already made 12 years ago the idea to incremental update the updated .dll files with the integrated profile updater but okay, maybe we need to reach the 1 GB download size until nVidia realized that this is a no-go.

The driver itself is stable on all my test machines and was clean installed with DDU.

The more interesting thing DisplayPort Firmware updates!

This update is merely for the UEFI portion that governs the output of the GPU and has absolutely no impact on the vbios as each card has its own specific vbios made by whichever company you got it for specifically for your card so nVidia would not touch that as every card has different parameters set sue to the different hardware used. This means no one will have their vbios change when they do this. This is only to update a small portion of the firmware that supports the display out and not the portion that actually governs your card’s clocks, voltages, and fan curves – they are two completely different things so don’t be worried about your vbios being changed/modified when using this UEFI update.

The update itself is for Windows 7 up to Windows 10.

What the latest nVidia driver won’t tell you is that there is also an (optional) firmware update available. You get more information about it here. The download for the required update utility is available here.

This update also fixes a black screen issue, which is repeatedly reported over the /r/Windows10 Reddit thread which seems to affect the latest Windows 10 April Update 1803.

To enable the latest DisplayPort 1.3 / 1.4 features, your graphics card may require a firmware update.

Without the update, systems that are connected to a DisplayPort 1.3 / 1.4 monitor could experience blank screens on boot until the OS loads, or could experience a hang on boot. 

The NVIDIA Firmware Updater will detect whether the firmware update is needed, and if needed, will give the user the option to update it.

If you are currently experiencing a blank screen or hang on boot with a DP 1.3 or 1.4 monitor, please try one of the following workarounds in order to run the tool:

  • Boot using DVI or HDMI
  • Boot using a different monitor
  • Change boot mode from UEFI to Legacy; or Legacy to UEFI.
  • Boot using an alternate graphics source (secondary or integrated graphics card)

Once you have the tool downloaded, please run the tool and follow the on-screen instructions.

This sounds interesting and I tried it, it worked well it detected my graphics card and the upgrade wizard started its magic without any error. Keep in mind that whenever you use a modded BIOS you might see an error or the firmware won’t apply, in this case just flash a stock BIOS and then after you’re done flash you modded bios afterward to solve this little issue.

After you’re done with the update (prepare for screen flickering and some black screens during the detection and installation!) you need to restart your OS.

Closing Words

This update seems to important to be ignored and it’s not understandable why nVidia did not integrate it within their latest driver package (13,7 MB more wouldn’t hurt the 400+ MB driver package). The firmware upgrade was done in 1 minute and everything worked for me.
