# Compatibility Challenges with M4 Macs and Ultrawide 5K2K Displays
Following the introduction of Apple’s latest M4 Macs, users have enthusiastically welcomed the new technology. However, as more individuals incorporate these devices into their daily tasks, unforeseen compatibility challenges have surfaced, especially concerning ultrawide displays. This article explores the reported difficulties related to M4 Macs and their compatibility with ultrawide 5K2K displays.
## The Issue: Absence of HiDPI Support
Users on various platforms, such as the [Apple Community forums](https://discussions.apple.com/thread/255845196?cid=em-com-watches_email_thread-view_the_full_discussion-en-us-11282023&sortBy=rank) and [Reddit](https://www.reddit.com/r/macmini/comments/1hatxb2/comment/m1bbo97/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button), have indicated that M4 Macs do not adequately support ultrawide displays at a resolution of 5K2K (5120 x 2160). The main issue is that these Macs lack the necessary resolution choices, leading to a blurry user interface and text. This situation is particularly vexing, as the same displays perform correctly with older Macs, including both Intel and prior Apple Silicon models.
### User Feedback
Numerous users have recounted their experiences, emphasizing the sharp contrast in performance between M4 Macs and their older counterparts. One user remarked, “Even though I can select the same resolution on my Mac Mini M4, it doesn’t display HiDPI, and it (actually) appears worse.” Another user supported this observation, stating, “Identical issue here – MacBook Pro M1 Max: no issues. MacBook Pro M4 Max: 3840 x 1620 resolution is gone.” These testimonies highlight a notable decline in display performance for those using ultrawide monitors with the newest M4 Macs.
## Alternatives and Third-Party Solutions
While some users have attempted to alleviate these problems with third-party software like BetterDisplay, this option has its limitations. Although BetterDisplay can activate HiDPI settings, it frequently results in a drop in refresh rate, going from 75Hz down to 60Hz. This trade-off may not be acceptable for users who value smooth visuals and responsiveness in their work or gaming scenarios.
Currently, Apple has not formally recognized these compatibility concerns, leaving many users feeling uncertain. For those contemplating the acquisition of M4 Macs, the general recommendation is to wait until a solution is implemented.
## Conclusion
The compatibility challenges between M4 Macs and ultrawide 5K2K displays have caused unease among users who anticipate flawless integration of their devices. As Apple pushes forward with innovation, it is essential for the company to tackle these issues to preserve user confidence and satisfaction. For the time being, prospective M4 Mac buyers should be mindful of these difficulties and assess their display requirements prior to making a decision.
