Displayport cable question

[Paen9k]

Thank you to everyone in my other thread that helped me with my refresh rate, I was unable to switch my 144hz monitor up past 64hz until someone suggested I use a displayport cable which worked great.

Was just curious with this new cable I have some different options under my Nvidia display settings I have the PC options and then Ultra HD, HD, SD options with many selections under that, was just wondering what these are for?

Those are resoltuion settings, SD would be 480p, HD is 1080p and Ultra HD is 4k (1440p or 2160p)

If you use a DVI cable at 144 Hz, it must be Dual Link DVI-D

It is extremely odd that the correct cable wasn't provided "in the box" ... I have never seen HD, SD, Ultra SD in any of the menus I have navigated, resolution has always been listed in numbers

1920×1200 (WUXGA)
2560×1440 (WQXGA)
2560×1600 (WQXGA)
3840×2400 (WQUXGA)

HD, SD, Ultra SD usually refer to TV resolutions

Yes. SD stands for Standard Definition which is 480p. HD stands for High Definition which is 1080p. Ultra HD which is 1440p. 1440p is what we call 4K. I can honestly say I don't know what the resolution is for 480p. However standard resolutions for 1080p and 1440p are. 1920x1080 and 2560x1440. This means that there are 2560x1440=y. Where "y" is the number of pixels on the screen at any one time. If you're goal is to run in 4K then select ultra hd. The point of these different resolutionstyles is for a cleaner image. Let's say you take a 24" monitor and run it in 1080p. OK looks good, but now turn the resolution to 1440p on the same 24" monitor. You now have many more pixels available. Which allows the little differences between color and geometry to be much smoother. You're transitioning from pixel to pixel in a much smaller area. This makes lines and edges much sharper. Hope this helps.

Yes. SD stands for Standard Definition which is 480p. HD stands for High Definition which is 1080p. Ultra HD which is 1440p. 1440p is what we call 4K..

4k is actually 2160p

1920 x 1080 = 1080p
2560 x 1440 = 1440p
3840 x 2160 = 2160p

Thanks for the correction. For my own information. What is 1440p then?
