EA has updated its guide on how to fix blinking and flashing display issues in Need for Speed Unboundstating that affected users should update their motherboard BIOS, not their GPU BIOS.
“We’ve seen reports of blinking/flashing display issues from people on high-end PCs (NVIDIA RTX 40 series). After testing, we found a solution which is to update the motherboard BIOS. Please contact your motherboard manufacturer’s support page to get the latest system BIOS,” EA explains in its revised community forum post.
“Previously, the fix was incorrectly listed as a graphics card vBIOS update,” EA added.
Incidentally, EA no longer specifically singles out the GeForce RTX 4090, although it refers to the “RTX 40 series” in parentheses when it comes to a high-end PC. It’s also not clear what exactly is causing the problem that would require updating a motherboard’s BIOS, or if certain chipsets are more likely to encounter this problem. It remains a strange situation and resolution.
However, the same precautions apply – back up your data before flashing your motherboard BIOS. You should also be aware of any custom settings and tweaks you may have made in the BIOS, as these are usually reset to default when you update the firmware. If it’s an option, save/export your settings and/or profiles to a USB flash drive before updating and import them back afterward.
Over on the EA Forums, a community manager has written a post that will be updated over time with known issues as they are discovered and any applicable workarounds. It’s a relatively short post at the moment, but one of the bugs described has to do with the displays flickering and flashing during the last game play Need speed Publication.
“We’ve seen reports of blinking/flashing display issues from people on high-end PCs (NVIDIA RTX 4090). After testing, we have found a workaround/fix which is to update the BIOS on the 4090 graphics card,” the Community Managers wrote.
It’s not too often that a game publisher recommends updating the BIOS on your graphics card. In fact, I can’t recall a single time this ever happening before (feel free to enlighten me in the comments if this has indeed happened before). Typically, the workarounds for these types of problems involve game patches and driver updates or other non-BIOS changes.
The NVIDIA GPU Firmware Update Tool detects if the firmware update is required and gives the user the option to update it if necessary.
If you are currently seeing a blank screen, please try one of the following workarounds to run the tool:
- Make sure you are using the latest SBIOS from your motherboard vendor
- Change boot mode from UEFI to Legacy/CSM
- Boot to an alternative graphics source (secondary card or integrated graphics card)
- After turning on your system, wait for your operating system to load with the graphics driver installed
According to NVIDIA, a firmware update is sometimes required to ensure compatibility with certain UEFI sBIOS. Without them, the company says, graphics cards in certain motherboards can show blank screens when booting the operating system in UEFI mode.
As always when it comes to things like this, it’s a good idea to back up your data beforehand in case something goes wrong and you need to use a second PC for a while. It’s also a good idea to invest in a UPS backup battery – a power outage in the middle of a BIOS update can ruin your day in a hurry.
