Is my 4K TV a defective TV?

Recommended Posts

Posted · Original PosterOP

 

My TV shows no difference between 60hz and120hz. Since it´s the first 4k TV I have I´m not sure if I´m missing something on the set up. Or the TV is simply defective.

 

I´ve used the tests at testufo. The results reinforce that the TV is not refreshing at 120hz.

 

Here are some pics of some tests: mouse and text scrolling.

at 1920*1080 the results are the very same.

 

How does it look in your 4k TV? Can you help me with a photo of your TV at 120+ hz?

There are basically no TVs that support a 120hz input. Many have a 120hz refresh rate, but cannot display 120fps. The 120hz refresh rate is only so that it can play both 60/30fps and 24fps content without interpolation. Displays that only have a 60hz refresh rate will need to do a 3:2 pulldown for 24fps content.

What TV do you have, are you sure the panel actually supports 120hz?

 

TVs don't have Display Port on them, so 4k@120hz isn't achievable since HDMI 2.0 is the current bandwidth limitation. 

See this video Bitwit released today for explanation on that > 

 

As for 1080p@120hz, you should immediately be able to tell the difference between 120 and 60hz just moving your mouse around.

Not all 4k Displays support 120hz 1080p, and none support 4k 120hz.

 

There ARE 120hz capable TV's out there, real 120hz. But only when run at 1080p.

 

understand that many that spec 120hz,  240hz,  and above will not be real input frequency. Rather it will refer to things such as PWM backlight control and other such motion smoothing technologies.

 

In your case, if you are indeed using the correct input and the correct profile, and still not getting 120hz at 1080p then its likely the 120hz which is being stated in the spec sheet, is motion interpolation technology, and not 'real' 120hz.

 

 

Advertised VDU technology specs have ALOT of bent truths, and some straight up lies. Its not a very consumer friendly environment, so proper research is needed if you want to avoid buying a lemon.

hi,

 

Sorry for the late answer.

My TV is a q60r Qled Samsung. A model launched this year. Samsung webpage says it goes at 240hz. TV says it´s at 120p (is it the same 120 hz?) when configured at 1080p. Yet the photos in the link above shows it isn´t at 120hz. Moving the mouse shows no difference either.

@SolarNova: Many pages says it´s native refresh rate is 120hz or even 240hz. Samsung states 240hz.

 

@badreg thanks, although I don´t understand what you mean.

From Rtings.com

The Q60R supports most common resolutions and refresh rates, including 1440p @ 60Hz, which is not supported on the 2018 Q6FN. Most high bandwidth signals require Input Signal Plus to be enabled for the port in use, which is the new name for HDMI UHD Color.

It can also display chroma 4:4:4 or RGB content properly, but only when the input label is set to 'PC.' The TV usually automatically detects this automatically.

Note that in PC mode, many of the settings are unavailable and there are only two picture modes.

Chroma 4:4:4 does not work properly with 1440p @ 120Hz.

The 43" and 49" models have 60Hz panels, and do not support 120Hz inputs.

Mine is a 55".

I just want the TV to run 1080p at 120hz. (then I´ll see how it goes at higher resolutions)

 

Also at rtings.com it says 120hz native refresh rate.

Is there a program to see the list of components of TV: Processor, ram etc?

 

Does the Nvidia and freesync lacking compatibility matter?
