I just got a new monitor as a birthday gift, but it only has a DisplayPort while my PC only has HDMI ports. I have a couple of questions: First, will HDMI 2.1 be able to support 1920x1080 at 240Hz? Secondly, if I connect using HDMI 2.1, will it perform at its maximum potential, considering that my PC's HDMI port is quite old (around 7 years)? Sorry if my English isn't perfect! Thanks for any help!

To start, can you tell us what GPU you’re using? That’ll help figure out what you can actually achieve.
Check the specs of both your monitor and GPU, along with the HDMI cable you're using. That’ll provide clarity on the maximum capabilities you can expect.

I have a GTX 750 Ti.
