50 inch 4k tv as a monitor?

That TV doesn't operate at 120hz on a PC. It actually operates at 30hz.

For a desktop monitor, it might not be so bad, but gaming at 30hz may not be enjoyable, not to mention the power needed to run it would be costly.

Thanks.

Just curious, how much could this possibly cost to power?

This is 2160p ... and I know input lag on tvs is generally not ideal for computer gaming.

There is a 4K TV by Seiki that can be used at 120 Hz when run at 1080p.

Keep in mind that running this TV at 1080p results in no distortion, because it just uses 4 of the 4K pixels to represent one of the 1080p pixels.

So, anyway, just saying that you likely get 120 Hz 1080p gaming, which is pretty sweet, and then you get 4K internet browsing. Not sure if you'd want to game at 4K, because your GPU would have a thermonuclear meltdown, or you'd get like 4 FPS (which, is less than the 30 Hz limit at 4K).
 
The tv will have 7ms to 15ms .......... Im @ 1ms to give you a idea @ 70Hz

youll be 15ms FPS games will lag on that tv, fonts will also not show properly. gl

What is your basis for this assertion?

Have you ever watched a movie on your PC? Do you recall if you watched that movie at less than or greater than 30 Hz?

I'd say because your monitor wont be showing you frames at anything above 30FPS even though it's still working to generate them. Desktop use would seem sluggish and gaming would just be silly limited to 30FPS for no good reason.

As for the movies, the "true" videophile refresh rate is something like 23.9Hz because of how the movies are filmed. The video file itself is encoded at a particular rate and most video card drivers/multimedia software will work to playback the file to as close to that rate as it technically can. The tiny frame drops or double frames watching on a 60Hz monitor don't really bother most people for daily viewing, but a 30Hz monitor would technically be closer to viewing as the source intended. Kind of the reverse of the soap opera effect people complain about watching 120Hz tv.

Hmm, I'm not sure I agree. It's odd to wrap my brain around the idea how 30 Hz can be too quick for a movie, and yet seem too slow for desktop use?

I'm pretty sure the screen I'm looking at right now, is practically a still screen and wouldn't benefit from super high framerates, so I seem to think 30 Hz would be great for things like browsing the internet, watching movies, doing work like studying PDFs and composing code/documents, etc.

Hmm I just wonder what would seem sluggish. You mean like scrolling a website vertically? What kinds of things? If you mean gaming, I submit that you would use this Seiki for 1080p gaming at 120 Hz, which is probably better than most displays can do right now?

That's exactly what I mean by sluggish on the desktop. Fast scrolling would be choppy, the mouse would be choppy, you would more often catch windows not closing completely when you hit the x but still drawing half of the bottom of it for a second. Its definitely usable, but it wouldn't have the same smoothness as a 60Hz screen. It would kinda perform how you'd expect a cheapo tablet to perform, usable but just a little slower than it could/should be. Not an experience i'd pay that kind of money to have, surely.

The movie thing I dont particularly "get" as i'm not a videophile or movie buff, just sharing the explanation of why 30Hz refresh is technically closer to the source material and why that person said it would be good for movies but nothing computer-y.

Maybe... movie is pre-rendered at a fixed framerate. Computer just displays as it goes, so if it is halfway through doing something while frame is changing, then maybe get a noticeable hitch?

Or maybe I need more coffee.
 
Ryan Shrout at PC Perspective reviewed the 39 and 50 inch Seiki TVs used as a monitor. I can't find much in the way of written reviews at his site, but he talked about them on his podcasts. He definitely got 30Hz when it was connected to a PC. Even on the Windows desktop he noticed mouse movements and animations didn't feel as smooth as a 60Hz monitor.

I'd like to have a 32 to 39 inch 4K TV as a monitor, but I think I'll wait for one that is truly at least 60Hz.

Oh 🙁

Yes a 32 inch would be awesome. Unfortunately it looks like they will cost $2500++

Maybe it has a sufficient recent iteration of HDMI like 1.4a?

Anyway I'm just passing on what I've read. I was doubtful at first until I saw the Refresh Rate Multitool video linked a few posts ago
Click to expand...

HDMI 1.4a does not support 120hz. It supports only 60hz, but can do 60hz 720p in 3D through frame packing. Frame packing allows the input to receive both right and left images in one packet, so it doesn't require 120hz of input to support 60hz 3D. However, in 2D, it is limited to 60hz.

HDMI 1.4b can, but I still have never seen one in production, even though there is a standard.

Edit: Now if you can use that hack to get it is another question, but that isn't exactly native support and still may have issues as Chad found with that Plasma. It could do 120hz, but only up to 720p.
