I have read that HDMI will limit your frames to 30fps. Is this true or can you get better frames with an HDMI? I am going to be gaming on a 27" TV that only has HDMI so will that mean that I have to get a new monitor?
HDMI will only limit your frame rate/refresh rate to 30fps/Hz if you're using a 4k monitor. You're probably using a 1080p monitor, so it should not create a bottleneck like that.
