As a contention to note, According to VESA, the display port standard in terms of CABLE does not matter. A 1.2 cable can support a 1.3 or 1.4 signal. Maybe in the future with DP 2.0 there might require a new cable standard to support the "double bandwidth" but maybe not, for now the cable version doesn't matter.Zace wrote: ↑16 Dec 2021, 08:26XG2431 does not come with HDMI cable. It comes with display 1.2. For HDMI to be faster maybe he tried a HDMI 2.0?Chief Blur Buster wrote: ↑16 Dec 2021, 01:47Not necessarily.
Not necessarily - Newer HDMI can be very good nowadays. Also firmware differences on different models can switch HDMI-vs-DP processing lag into favour of one or the other — it is never DP consistently better, nor HDMI consistently better.masterblaster wrote: ↑15 Dec 2021, 15:59What are you talking about?
HDMI should never be better than DP.
However, there wasn’t supposed to be a major difference — This merits further analysis. I’d inform ViewSonic.
Also make sure to test apples vs apples on monitor features (VRR on versus off)

Which leads me to my "don't buy chinese knockoff products just because they are cheap" rant. I can't tell you how many people on reddit have monitor issues because they buy the cheapest most POS cable possible. I always buy certified, for DP that means Club3d or CableMatters, both of which can be found on Amazon for very fair prices.A standard DisplayPort cable, including older cables, will work for any DisplayPort configuration including 4K and multi-stream capabilities. All certified DisplayPort cables support HBR2 (High Bit Rate 2), which can support 4K at 60Hz, or up to four 1080p displays using multi-stream.
While these same cables can in many cases be used with the latest-generation HBR3 and Display Stream Compression (DSC), DP8K-certified cables are specially constructed to ensure the best performance for these high-bandwidth applications.
DisplayPort uses packetized data, similar to USB and ethernet, to send digital display and audio data. Unlike older video interfaces, you don’t get a “better” picture or other incremental improvements with a more expensive cable, but a poor quality cable could lead to data errors and obvious corruption of the video or audio data, and may be less reliable over the long term.
Which as a funny note, I am running a certified Club3d cable right now via display port, some users have noted supposed input lag issues. I have no issues with input lag, but I also did not use the cable the monitor came with. Perhaps their cable provided in the box isn't of high enough quality to ensure proper data transmission....
