What's the maximum refresh rate if sending a 3840x2160p signal over HDMI to this set? 24, 30, or 60Hz?

Don't actually own this set (yet), but, according to the HDMI industry association, 4K via HDMI 1.4 maxes out at 30Hz. See http://www.hdmi.org/manufacturer/hdmi_1_4/hdmi_1_4_faq.aspx#21. Would be great to know if LG or any other mfr already install HDMI 2.0 in any 4K set now. HDMI 2.0 standard was officially released in Fall 2013 and allows for 4K at 60p.

right now it is capped at 30 hz. I called LG and they claimed to be working on some sort of upgrade solution which they ballparked being ready by Q3

Most likely you are not selecting an appropriate display resolution or frame rate to send to the TV. The highest settings this Tv can accept from the PC input is 1024x768x60Hz Right click your Desktop -&gt; Properties -&gt; Settings Tab -&gt; Click on the secondary display device (Your TV) -&gt; Advanced -&gt; Adapter -&gt; List All Modes -&gt; Select "1024 by 768, True Color (32bit), 60 Hertz" -&gt; Click "Ok" 3 times to get back to the desktop -&gt; It should work now

So while HD4000 is more than capable of displaying 2560x1440 the screen doesn't use the faster implementation of HDMI. This means that you can only display full resolution at 30HTz instead of the standard 60. From experience this feels very fuzzy and probably not worth the trouble. 1080P runs fine on HDMI but to get full res you need either dual-dvi or displayport.EDIT: After doing some reading I realized I gave some incorrect data. The screen is speced to be able to run HDMI1.4 which is good enough to run full resolution. If you are using a computer with HDMI1.3 you will be stuck at 30HTz like I explained above.

It will be playing at 60htz, the default rate. You will only be limited to 30htz when running at 4k, since hdmi 1.4b still has limited bandwidth. There are methods however to get the tv run at 120 htz when hooked up to a computer.

HiThank you for your interest.DisplayPort 1.2 : 60HzHDMI 1.4 : 30HzThank you.

It's completely irrelevant honestly. Either one is significantly more than you need in a home theater setup. The refresh rate of your TV isn't relevant, the refresh rate of the signal is. The highest bandwidth intensity comes from 1080p/60 and that clocks in at just under 3 gbps, and uncompressed 7.1 audio could only add 36 mbps max. Even first generation HDMI cables had to be able to carry over 5 gbps, anything more isn't needed.

Try changing the resolution or the refresh rate. Maybe the cable is defective?

I'm running 4 @ 1920x1080 and all are 24 inches and up with very few issues. Make sure your power supply is at the upper end of the spectrum, I have to unplug my monitors when I reboot which is a little irritating, but it seems related to the power supply and nothing else. Also pay close attention to the listed issues with DVI / HTMI / Display Port.

With DisplayPort 1.2 it will be 60hz. DP 1.2 allows Multi-Stream Transport (MST) support which translates to this monitor being recognized as two 1920x2160 monitors each at 30hz. If you go the HDMI 1.4 route you will need a card with two hdmi outs for pretty much the very same reason. A single HMDI will only give you 30hz.

Amazon is wrong. Other sites has this @ 60. If you do a search on the LCD it will say 60Hz

It depends how one defines the refresh rate. My understanding is the refresh rate is technically 60 Hz, but Toshiba employs their "ClearScan" back lighting technology to raise the effective rate to 120 Hz. An explanation of how this works can be found on Toshiba's forum at http://forums.toshiba.com/t5/Televisions-Knowledge-Base/TOSHIBA-ClearScan/ta-p/361268. I have the 32 inch and the 23 inch versions of this product and, in my opinion, the picture is great and handles fast-moving action, such as sports, very well.

120.....but keep in mind your video card has to support 120. MOST video cards do not support 120 on hdmi, but newer ones will.

They might be able to at lower refresh rates, but display port is generally better at that high of resolutions. The highest dvi supports at 60 hz is 1920x1200.

I believe its a 60 refresh rate. I have had this tv for over 2 years now and not one problem. I would recomend it. Itd better picture than a new samsung i recently bought.

No, most games are maxed at 60. I play the 360 downstairs on my LG 120hz refresh rate and actually have to turn it off because of ghosting. Most 120 sets have an option for "game mode" which turns 120 off and goes to 60 for this reason.

60Hz on the display port... but the NVidia card in my notebook pc could only handle 30.
