I purchased a Razer Blade 18 (2025). It is a great laptop, one of the best I have ever owned, and also the most expensive.
I have sensitive eyes, so I am very careful when choosing a laptop. The most important factor for me is having a screen that is comfortable to look at. The display on this laptop was extremely comfortable and easy on my eyes. I could use it all night without experiencing any eye fatigue. That was the case until I updated the MCU firmware.
Razer Synapse displayed a notification recommending that I update the BIOS and other software. After updating the MCU firmware, the laptop became difficult to use. The screen now causes significant eye discomfort, and I experience burning and dryness in my eyes. After just 10 minutes of using the laptop, my eyes become more fatigued than they previously did after an entire night of uninterrupted use.
It appears that the MCU firmware update somehow changed the way the display operates. Before the update, the laptop was running at Full HD resolution with a 440 Hz refresh rate. After the update, the laptop restarted and automatically switched to 4K resolution with an extremely small scaling setting, well below the recommended value. I immediately noticed discomfort in my eyes when looking at the screen.
I have tried different display modes, color profiles, and scaling settings, but nothing helps. The burning sensation in my eyes persists.
Perhaps the MCU update enabled temporal dithering. This situation is extremely frustrating. I paid $4300 for this laptop, and through no fault of my own, I can no longer use it comfortably after installing an update recommended by Razer.
To resolve this issue, Razer should provide an option to roll back the MCU firmware to a previous version.
I would appreciate any assistance in resolving this problem.
