Hardware & Technical New TV Lolz.

So I got a shiny new 55" Samsung TV. 4k, looks great. (Not top of the range, but not the cheapest).

Plugged my PC in, it detected it straight away. Works wonderfully. My GPU lacks the power for 4k gaming.
But the 4k desktop looks great.
Except.....

Major mouse lag, and everything felt "slow"!

So I spent ages updating drivers, faffing with the TV settings, etc.

Nothing. I figured maybe my 770 couldn't handle windows at 4k.

So I faffed some more. Then gave up, feeling a bit sad. (Thought about returning the TV, but it's not mine to return. Lol)

So I just accepted it for a week or so.

Then decided to see if Skyrim (original) would run at 4k.
Fired up fraps, fired up Skyrim at 4k.
29fps. Bah. I guess it can't!

Switched it back to 1080p, and left fraps running by accident.

Fired up the game again.

29fps...!

I sat baffled for a moment. Then checked the game wasn't running ENB stuff. Tried again.
29fps.

Tried ED (at 1080p) which used to run at 60fps.

29 FPS.


I checked all the nVidia settings. Nothing odd.

Checked windows settings.
Nothing.

Then it hit me.

Check the TV as a device in windows.







30hz!! Why windows?!

Lol

Set it to 60hz. Smoooooooooth desktop and games again.
No idea why windows would decide to set it to 30hz.

May or may not be related, but I had an issue with nvidia drivers 390.65 where after the monitor resumed from standby the desktop would be set to 30Hz and 60Hz+ modes were not even listed as available (had to restart).

4k60 (RGB or 4:4:4) requires at least HDMI 2.0, and most TVs won't default to that input standard because most video content is 24Hz or 30Hz and even many 4k sources use old HDMI standards.

I wonder what version my HDMI cable is... Lol

And regarding the mouse lag, most TV's don't have great latency. That's one of the things that monitors prioritize.

Yeah, I much prefer a monitor over a TV, but I don't have room for a desk and my PC is basically just a console these days. Lol

Now it's set to 60hz it's all fine and smooth (by my standards) again anyway.

Lol, I did something similar, took me over a week to notice it too, just thought it was my imagination!

Some resolutions (like 1440p) the stupid tv just defaults to 30Hz, it's fine with 4k@60Hz over hdmi but strangely lowering the res results in a lower refresh... Just the quirks of using a TV as a monitor I guess :p
