Blurry text when there are a lot going on the screen.
4 Stars
Blurry text when there are a lot going on the screen.
I want to use my PC from across the room so I can access my PC in my bedroom too with at least two monitors. The quality is good and easy to set up with no noticeable latency.The only downside of this KVM extender is that when there is a lot of stuff going on, especially colorful images or a lot of text like an essay, everything becomes blurry. Sometimes it's unreadable. If you look at my screenshot, the top part of voicemeeter app is too blurry to make out.The customer service is excellent. They are understanding and provide useful feedback to me. I always heard them back within a reasonable time frame.While asking on Reddit, one person mentioned that their HDBaseT ones(also from this company) working well without the blurriness problem.
Thank you for your feedback
