A low point of my first week came when I plugged into my external display, and the image looked really bad. When I plugged it into my new Mac, the text looked terrible. There were strange color fringes on the edges of characters. Some narrow strokes appeared as blue or red blurs. The effect varied with typeface and application, but it was universally distracting and difficult to read. My first hunch was that something was going wrong with this. Disabling it via LCD Font Smoothing helped somewhat, but the overall image was still noticeably worse than I had experienced before.

When a display is first connected, it identifies itself and describes its capabilities by providing a blob of bits called the Extended Display Identification Data EDID.

The Wikipedia page helpfully provides the full spec. My Dell emits 11, meaning that it claims to support all three color modes. Fortunately, somebody else has already solved this.

I frankly never minded the new keyboards — the positive clickiness makes up for the low travel for me. Ah, I see. I thought I am going mad.

    I tried this but my screen actually looked worse! I mean my screen was pretty good as it was and I thought this would give me a pure RGB to the display but I think in my case something is not right. From what I understand a true RGB signal should be such that the color settings on the display should refuse to be adjusted as the display color signal is now being driven by the computer but in my case I can still adjust saturation and such which makes believe something is not right to start with.

    Also, I lost the underscan and overscan features, after this change the display is being overscanned. I wish there were a terminal command that could identify if I am indeed sending out a true RGB or what. I have to investigate this further. I spent way too much time trying to fix it with font smoothing :s. Also, for others reading these comments in the future, I have the same monitor as the author. All hardware involved:.

    This was really helpful, thanks.

    I was worried that it was all in my head or that I needed another cable or something. It is so much better now. Thank you so much that just helped me a lot. I also have a Dell monitor. What I found out is that it could be due to the graphic drivers. My quadro k shows the rgb color, my rx always shows the other color space yr…. I noticed immediately that clarity was sub-par on a number of os elements, especially red. It looks like the os decided to default to YCbCr which is causing significant degridation of the video quality in the red side of the color space.

    I have an eGPU on order, but really want to figure this out before then. I notice it in the edges of reds the most, just as you do. I just bought the Mac Mini, and when I started migrating my system from my rMBP, I though my eyes were playing tricks on me; on my 4K screen that was working perfectly fine with my old computer, I now saw washed out colors, blurry fonts, the whole shebang.

    After trying everything else I could think of in terms of hardware and software, I started googling, and found this page. Posted on Feb 16, PM. Page content loaded. Feb 16, PM. First check that the HDMI cable, and the adapter if you're using one, are securely inserted at both ends.

    In the window that opens on the external display, set the Resolution to Scaled , and select the HDTV resolution that matches the display usually either p or i.
