The HDMI length affects delay, so it matters.
The HDMI length affects delay, so it matters.
I've been looking to enjoy pc games on TV for relaxation. However, the lag from pressing a button to seeing it on screen is quite noticeable—around half a second. This isn't ideal for most games. Is this due to the HDMI cable length or a general gaming performance problem? I noticed my old Wii works fine over HDMI, so maybe the cable length is the issue. Using an Amazon Basic 9.8-foot cable helped improve the experience.
The time needed to move down a long HDMI cable is very short. Length probably isn’t the problem. The cable adds almost no delay compared to other system parts, since it travels near light speed. I suspect your issue lies with the TV. Most TVs have high default latency. Could you check if it’s in game mode?
Electrical signals move extremely quickly. The time lag from the connection will be very small—just a tiny fraction of a second—so it’s practically negligible. The problem probably lies elsewhere, such as with the TV handling final edits.
Beyond the details already shared about signal speed, staying within the standard specifications ensures proper performance. The exact length limit isn't clear yet—I’d need to check the documentation—but as long as the cable functions according to the current version, it should perform adequately.
I had already guessed about the cable length, so I decided to check. It's an LG model from around 2019. I saw "instant game response" in additional settings, but since it was already enabled it didn't make a difference. There was also a special picture mode named gaming, which seemed to improve the experience. Thanks!
i turned off and back on my tv using a 25-foot cable, but 10 feet seems to be the safe limit. display port doesn’t have strict length rules, though. for 4k60+, it might work but i’m not sure.
Explore the factors affecting the path from button press to displayed image. Various elements influence latency, such as connection type (wired or Bluetooth 2.4GHz), TV model, and game mode support. Many displays perform extensive image processing, like interpolation, which can introduce noticeable delays between input and screen output.
