PC Desktop able to run HDMI/4K?

[rdl]

Yep, know all about that and use it. On the last TV it was called "Aspect Mode 1:1", on the new TV it's called "Aspect Ratio: Full (100%).

Fixes the overscan just fine, HDMI still has all the same strange appearance problems as before. I don't think it's because it's a TV, I think it's because it's HDMI, mainly because all the problems disappear when the exact same equipment is switched to VGA. I should probably try HDMI out on a real monitor sometime just to see.

And what is the point of this HDMI overscan anyway if the TV doesn't need it? Just more messing around with the signal for no purpose other than it can?

Graphics card and HDMI standard has nothing to do with this. It is a TV.

Check GPU driver control panel.

Because stupid TV broadcasters made a CRT overscan workaround being standard. Quiet often putting crap on the edges of the video even nowadays.

To address the OP's concern:

A huge 4K monitor is NOT going to help you see things better. It will actually appear to have very tiny icons and text on it. What you want to do is decrease the resolution, notwithstanding the size of the monitor.

The graphics card used with the TV is an Nvidia GTX550 and I actually don't recall ever having run the Nvidia control panel utility until just now, so it's not likely I "messed with that setting".

As far as I can tell the driver doesn't even have an under/over scan setting. It does have some scaling options, but they're all set on the default 1920x1080. None of this actually matters anyway since all the visual artifacts I can see using HDMI completely go away using VGA out of the DVI port.

I really don't see that there is any benefit to using HDMI from a PC to a TV, unless of course there's no DVI or VGA input on the TV.

If there is DVI on the TV, then no picture benefit. However you can output sound over HDMI too. VGA on the other hand is crap, especially on higher resolutions like 1080p.

That's odd, my Nvidia control panel doesn't have that. It just says

1. Select the display you would like to change:

(Under that is the icon for the TV)

2. Apply the following settings:

(Under that all there is a panel with two tabs, one is for "Scaling" the other is for "Position")

No mention of HDTV anywhere. Maybe that's a newer driver version from what I have. I haven't updated the driver since the last time I reinstalled Windows, maybe 6 or 8 months ago.

Menu will look different depending on driver version and even GPU used (even if installing from the same file).

To those who think a 4K TV is a waste of my time/money... I think you misread what I've been saying. I want the TV for general multitasking, videos, and overall more screen real estate. I don't want it FOR the text to be bigger, it's just it's necessary that the text is able to be larger along with the screen, and displayed the same way it is on my 19". I was making sure I could keep my zoom the same as it already is, and with a bigger screen, just have more room for it all.

HDMI looks great on higher resolution, BTW!

Sorry, I guess I did misunderstand then. BTW, have you ever noticed that the demo video on 4K TVs in stores repeats after a few minutes? That's because you can only fit a few minutes worth of video on a standard BluRay disc. Apparently they're working on a format for BluRay that will fit a 2hr movie.

Less than a 1080p with the same compression ratio but not few minutes. You could expect 4x reduced length worst case.

I did the math once and it came out around 6 minutes, but of course you're right it depends on the compression. If they compress it so much then there's almost no point in calling it 4K anymore, but this is why it's good news they're working on 100GB BluRay discs. Hopefully the compression will not be "too" bad. I know I can tell the difference with streaming (Netflix, DTV PPV) vs BluRay.

Oops, sorry for hijacking the thread!

The maximum ("legal") bitrate for bluray is around 48 mbps for both video and audio, 40 mbps for just video.  For 1 1/2h - 2h videos, bitrate would probably average at around 20-25 mbps

The 4k demos are probably encoded to use about 60-100 mbps, so about 4-5 times what's used for regular HD. Therefore, discs can probably store more than 20-30 minutes of 4k video.

There's a new version of blurays... quoting from another site:

Discs will be available in two varieties—66 GB dual layer and 100 GB triple layer with data-transfer rates up to 108 Mbps from a 66 GB disc and up to 128 Mbps from a 100 GB disc. The laser system is roughly the same as the current Blu-ray spec tuned for the new higher-density disc structure. Obviously, the pixel resolution will be up to 3840x2160, and players will have HDMI 2.0 outputs with HDCP 2.2 copy protection. Finally, HEVC encoding will be used.

Ultra HD Blu-ray players must be able to read both of the new formats as well as HD Blu-ray discs. Other mandatory features include support for high dynamic range in the form of SMPTE ST 2084 and 2086, which are open standards that include PQ gamma. The HDR info is encoded as metadata so the content can be played on a non-HDR display. Also, players must support frame rates up to 60 fps and color gamuts up to BT.2020 with 10-bit resolution. Finally, they must decode all the current audio formats and provide passthrough for all immersive-audio bitstreams.

Optional features that manufacturers can choose to implement or not include support for Dolby Vision and Philips HDR as well as DVD and CD playback. Another optional feature is called Digital Bridge, which will let the player copy Ultra HD Blu-ray content from the disc to internal storage if available. It also allows you to export an HD or SD copy of the content to an external device for portability. (The rep I spoke with didn't know if Digital Bridge would let you export full-resolution UHD content.)
