I have 2 identical 4k Monitor (Philips 276E8V). One of them is connected to my Pc using DisplayPort and the other is HDMI 2.0

I thought DisplayPort is newer technology so I expected better quality on DisplayPort, but I noticed the one which is connected using HDMI, shows more clear and more crisp fonts.

Does this make sense? or something is wrong with me graphic setting?

I am using Windows 10 and AMD Radeon 7770

  • HDMI = High-Definition Multimedia Interface whereas DisplayPort is not HD. – vssher Jun 5 at 16:24

    What resolutions are you using? Have you tried resetting both displays to factory settings? Have you tuned ClearType in the past? – gronostaj Jun 5 at 16:57

    "Does this make sense?" No. On identical monitors I would expect identical quality. Three things to check: 1) Swap cables to the displays (to rule out that it is a display and not anything else). 2) Are all driver settings the same? 3. You mention win10. I have seen poor (fuzzy) displays when scaling. A log/off and log back in (or a reboot) would fix that. – Hennes Jun 5 at 17:27

    @Hennes, good hints. I swapped the cables and got the same result. so seems some setting is different. I see too many factors here. different cable, different refresh rate and bit depth. So I'm confused – FLICKER Jun 5 at 18:06
