Can the iGPU in 285K support Dual 4K displays at 240Hz?
Can the iGPU in 285K support Dual 4K displays at 240Hz?
OLED for production screens usually isn't the best choice. You'll experience quicker burn-in compared to static displays, and text clarity tends to be lower than that of IPS panels. For 4k/240Hz, both the display output and monitor input need UHBR20 support. While a single 4k/240Hz IPS Black monitor works, it's not ideal for long-term use. Consider a 4k/120Hz IPS Black display instead, as it offers better eye comfort and is often optimized for extended viewing. I recently used a 27" 1440p/120Hz Dell Ultrasharp, which performed well—strongly suggest checking their selection for options that match your requirements. If the monitor supports full HDMI 2.1 (FRL) or DP2.x UHBR13.5+, it can handle those resolutions and refresh rates.
The initial plan was 49@120Hz IPS for better text clarity, considering OLED sub pixel layout and burn-in concerns. However, text clarity is excellent at higher PPI, and adjusting ClearType to MacType on OLEDs could help with burn-in. Burn-in information is available here: the links provided. Reg's feedback is appreciated.
I own a 240Hz QD-OLED and a 120Hz IPS Black display, yet the difference remains unnoticeable during regular tasks. Considering the slow response times on the Ultrasharp model would suggest I should have observed a difference sooner, it seems the issue might lie elsewhere. It's possible these other screens simply didn't perform well, as many earlier 4K models also struggled. Another thought is that they might be extremely sensitive to response times, which affects some users more than others. I can easily distinguish between 60Hz and 120Hz during typical work, but beyond that, the impact hasn't been as significant compared to panel quality, features, or calibration.
They aren’t VA panels, although the second generation offers a better ratio (3000:1 versus the first’s 2000:1). My current screens replaced a 34" 144Hz VA and a 24" 60Hz IPS (16:10) format, and while the black levels on the IPS Black aren’t as strong as the VA panel, they still outperform the IPS version.
When I purchased this one, my main goal was a display suitable for static text work, which is why I chose the Ultrasharp—it had IPS Black, 120Hz refresh rate, and eye care features.
The second-gen panel uses a newer subpixel design, and I’m confident the PPI will compensate. I note he hasn’t mentioned using productivity or office displays, so there might be an oversight in the comparison. Following Tim’s insights helped me feel confident selecting an OLED, as I was specifically seeking something reliable for long-term use.
I wouldn’t recommend a gaming LCD for productivity tasks, but I feel more at ease with an OLED. Still, I wouldn’t consider an OLED for a productivity setup unless I could reduce eye strain risks.
Thank you for your question. I'm looking for the precise model of your Ultrasharp. You mentioned you wouldn't choose a gaming LCD for work due to eye strain concerns or panel type, assuming VAs are unsuitable. If burn-in wasn't a concern, would you prefer your Ultrasharp over an OLED for productivity purposes? I'm also curious since I can obtain OLEDs at roughly half the cost and resell them at comparable prices every 2-3 years, allowing me to replace them when needed.
Ultrasharp models U2724D and the OLED is AW3425DW (it appears in my signature, though on mobile these aren't usually visible). For IPS displays, eye care features are impressive, but they aren’t the main reason for choosing this setup. IPS Black panels are quite appealing, and I haven’t seen gaming displays using these types of panels. Another concern is the need for various adjustments to ensure stability during strobing, flickering,<|pad|>. VA panels have fewer issues, though they’re not as extensive as IPS ones. In summary, while VA offers a good balance, I prefer Ultrasharp mainly for productivity-focused features. If similar OLED designs exist, they’d likely match in quality. Pricing is a key factor—my Ultrasharp costs about $300, while 27" OLEDs are significantly more expensive, especially at higher resolutions. I usually invest in displays longer-term, so I’d still favor Ultrasharp, though a 32" 4k/120Hz IPS Black would be around $800 (Dell: $970) and a 32" 4k/240Hz OLED around $750).
What do you mean by "extras you get with a productivity oriented display"? Are you referring to features like KVM, USB-C hub, etc.? Also, if I connect one monitor to the iGPU and another to a dedicated GPU, could there be issues such as different colors or OS problems?
Productivity screens are usually set up more accurately by default and come with better preset settings. They generally offer a wider range of input and output options and might feature different screen coatings. You'll also find various hub choices available, and some can be connected in series. When using both the iGPU and a dedicated GPU simultaneously, several issues can arise. Problems may occur depending on the vendor and model, though improvements have been made over time. Driver compatibility remains a concern in some cases. Hardware accelerated tasks shouldn't cause problems, but color-related issues are unlikely.
