acer predator xb271hu question

SimonNo1 · 15 Sep 2018 at 22:54

I own the following monitor acer predator xb271hu

When games drop below 100fps to my eyes it feels strange, kind of like a choppy feeling is this normal as the monitor is 165hz?

PC Specs

I7-7700K @4.6
32 GB DDR4 3200
GTX 1080ti
Z170A tomahawk MB

I use to think 60fps was fine but now it looks aweful to my eyes

Sounds like sync is on or sync is off

V-sync is not on only G-Sync is on.

Your eyes are used to higher FPS that's why 60 FPS feels strange.

I feel the same way with my 400 Hz TV.

Your 400Hz TV is still 60FPS... unless you happen to have a model which has a native 120Hz panel and you're at 1080p with HDMI 2.0, in which case you can max out at 120FPS.

My TV's native refresh rate is 100 Hz.

Well I don't know if that will be native, but regardless, that's a pretty old TV isn't it? It won't have HDMI 2.0 which means you won't get more than 60Hz anyway.

Yes, it's an old TV yet it has active not passive 3D. Are you saying it does 3D at only 60 Hz?

Regardless, I have the same monitor as the OP and I agree with him 165 Hz vs 60 Hz feels strange.

I don't know about 3D and how that works, you may be right, 3D will work at higher refresh, but I was just speaking to regular use and the limitations of HDMI 1.4 at 60Hz, regardless of native panel speed.

Yes, if you are used to a high refresh monitor @ 165Hz, dropping down to 60Hz will be noticeable.

Yeah I agree, I believe the HDMI input is only 60 Hz as you mentioned however the TV interpolates to a higher refresh rate for active 3D to work.

60 Hz in and 100 Hz out plus some clever backlight strobing and video processing to achieve faux 400 Hz CMR (clear motion rate) similar to ULMB on the XB271HU.
