2026 OLED Monitors Approach CRT Clarity, but Windows Must Adapt
In 2026, OLED monitors are nearing the clarity of 90s CRTs. However, achieving this experience depends on advancements in Windows technology and display integration.
Modern OLED monitors are getting remarkably close to replicating the cherished clarity of 90s CRT (cathode ray tube) displays, yet users must navigate through a patchwork of technological hurdles and operating system limitations to fully realize the potential of this evolution.
Revisiting CRT Clarity
Mark Rejhon, the founder of Blur Busters, notes that older generations can vividly recall the superior motion clarity of CRTs, while younger individuals are often unaware of what they missed. His team has developed tools, like the “Test UFO” browser feature, to help assess clarity during motion on contemporary displays. Even high-end LCDs in the mid-2000s lacked the speed and expressiveness of CRTs, resulting in noticeable ghosting as pixels struggled to keep up with motion.
The Challenge of Modern Displays
Today’s gaming monitors are worlds apart from their predecessors, but they still haven't achieved the motion clarity of CRTs. Rejhon emphasizes this pursuit in his work, explaining that CRTs, which could flicker light in a fraction of a millisecond, create smoother motion without the ghosting seen in current LCDs.
With OLEDs now on the market, there are even greater opportunities for richer colors and superior refresh rates. However, the challenge remains: Rejhon argues that advancements in displays will not fully bridge the gap unless software can adapt to these technologies.
Recent Innovations in Motion Clarity
Nvidia's G-Sync Pulsar technology illustrates this innovation, incorporating both hardware and software solutions to enhance perceived clarity. It combines variable refresh rate (VRR) capabilities with backlight strobing to create an effect akin to the instantaneous refresh of CRT tubes, reaching clarity levels perceived to be up to 1,000 Hz.
In late 2024, Rejhon collaborated with Timothy Lottes, a former Nvidia developer, to create an algorithm that significantly reduces motion blur for retro games. By simulating the phosphor fade effect of CRTs, the display manages to deliver a gentle viewing experience, vastly improving the sharpness of retro game graphics without requiring high frame rates.
The Role of ShaderBeam
ShaderBeam, a project developed by Mausimus, leverages this CRT simulation technology within video games. It aims to evoke the experience of playing retro games with CRT clarity. Since the fundamental operation of ShaderBeam is tied to frame timing and synchronization with display refresh rates, it requires meticulous coordination to achieve desired visuals.
Mausimus describes the complex setup necessary for ShaderBeam. Users may need to disable various GPU features, unplug secondary monitors and engage in registry edits to mitigate timing issues. This highlights that achieving the nostalgic CRT experience on modern hardware still demands a significant investment of time and technical understanding.
Benchmarking Performance
Performance benchmarks show that monitors like the Asus PG27AQWP-W, which features a refresh rate of 540 Hz, demonstrate a marked improvement in clarity compared to older LCDs when employing CRT simulation techniques. However, perfect synchronization is crucial; any lag in frame delivery may lead to unpleasant flash effects, undermining the immersive experience sought by users.
This technology presents hurdles for titles running on Unreal Engine 5, as notorious frame pacing issues can disrupt the smoothness expected from CRT simulations. Conversely, games such as Metroid Prime 2 demonstrate how ShaderBeam can transform gameplay enjoyment, providing clear and detailed motion that revives classic experiences.
Challenges Ahead for Widespread Adoption
Despite ShaderBeam's potential, the steep learning curve and technical requirements could deter mainstream adoption. Rejhon notes that while the technology shows promise, it requires further developer support through operating systems and graphics technology integration for easier accessibility.
In order for CRT-like clarity to be everyday reality, both hardware manufacturers and software developers will need to engage more deeply with technology standards. This includes advocacy for integrated shader support within operating systems and hardware that can effortlessly accommodate features like CRT simulations.
Key Takeaways

Looking Forward
The future of gaming monitors seems focused on replicating the qualities of CRTs while breaking free from the constraints of current operating systems. As developers and manufacturers increasingly explore these pathways, gamers can hope for an experience that melds nostalgic clarity with the conveniences of modern technology. The progression may be slow, but with continuous advancements, the vision of achieving CRT-level quality on today’s OLED screens is not just a dream—it’s a burgeoning reality.
