Does it NEED to run at 4K?

[pstarlord]

For RPG, open world games like Witcher III or Skyrim I like to play them in a more relaxed setting like, my living room.  My computer monitor is 144hz, 1080p, but I've got my 4K TV in my living room just kind of sitting there being neglected ever since I started gaming on my PC.  I know the input lag is one of the biggest down falls to most TVs, but for the games I'd want to play on it...it'll be fine.  So here's my questions.

 

1-Will using my TV make my GPU have to work that much harder to push a 4K signal into it, or will it be more like using an older console on it, like a PS3?  Obviously not a 4K system, but it has no problem being played on a 4K TV

2-Will the HDMI connection bottleneck the system?

 

I have a 1700X and a Vega 56 for my CPU and GPU.

Because of your GPU, I'd honestly recommend just running at 1080p with a sharpening filter via reshade. 1080p scales fairly well on a 4k display so it shouldn't be much issue. Though if you have the horsepower to run native 4k, go for that instead.

 

In regards to the input lag, check to see if your TV has a PC or Game mode. Those modes usually eliminate most of the post processing that adds input lag. Also, no, HDMI should not bottleneck the system.

First of all, if it's a 4k TV then its pretty recent, and most recent TVs have low input lag.

You just need to enable PC or game mode.

 

Second, 4k is a lot more intense than 1080p, but you can still run your game resolution at 1080 and it will be like playing on a 1080p monitor, just on a larger screen.

 

Third, I have no idea what you mean by "HDMI connection bottleneck the system"...

your display cable has nothing to do with your system performance.

HDMI 2.0 cannot support the same frame rates at 4k as Display Port.  Hence my concern about a bottleneck.
