Can we output Samsung Dex with 4K resolution on 4k output with wireless connection ? - Samsung Galaxy Note 20 Ultra Questions & Answers

I am looking to buy a new 4K TV and already own note 20 ultra. I observe that max screen resolution on phone is 3088*1440 that is QHD. Now if i want to play 4k HDR Movie via DEX on my 4K TV what will be the maximum resolution output ? Also will it support 60fps videos on monitor it surely does on phone and looks amazing (GEMINI MAN 2019 4K HDR 60FPS) looks smooth !!
I would also like to know if there will be any differences while connecting wirelessly or other via HDMI cable ???

4K at the moment is only avaible if you root your phone and dig a while. Wireless will always go 1080p and wired up to 2k.

Do you have some details, like a link to a howto? For example, is this 4K resolution real or just scaled 2K?

Do you record video in 4k DCI, 4k UHD or 1080p?

Which video setting is best?
Stick with 1080 in my opinion. 4k is still being adopted and chances are you don't even have a 4k display. There is no point in recording in a resolution that you don't have a display for due to its larger size in recording 4k

But in the future all TV will be 4k or better. If I'm taking baby videos of my son I would like them on be 4k. So, again, what is everyone using?

I don't think there'll be 4K on phones for awhile, 1440p has yet to be adopted with the exception of G3. Technology is always changing and it seems like you've already made your decision so why ask? Use 4K if u want, its up to you honestly.
By the way you're speaking about technology becoming old, by the time your son grows up 4K will become obsolete and another standard will be the standard. 4K prices are still very expensive and is not as mainstream as 1080p as it'll take time to adopt.
True but 4k would be more future proof than 1080p.
I guess the real question is what is the difference between 4k dci Vs 4k uhd?

UHD for Ultra HD
DCI for Digital Cinema Initiative
I could be wrong but I believe uhd is 30fps and DCI is 24fps. So for highest quality, choose uhd.

4k on 1080p TV's will look sharper (in a sense) as the picture is scaled to 1/4.
If the phone had true 1080p @60fps with sound, then that would be the best recording format..

Actually, UHD is not real 4K, DCI is real 4K. If you want actual 4K use DCI.

It's an ever growing problem that manufacturers are incorrectly marketing UHD as 4k when it isn't actually 4k at all.

This post doesn't make sense. The OnePlus One does record in 4k, and that's why we're discussing recording modes. Are you talking about 4K Display's on phones?

He's talking about displays. Obviously. Because look at the post he's quoting.

This is exactly how I see it. However I'm still recording in 1080p. Most of the stuff I film isn't worth storing, so 1080p is fine.
If I would go for 4k I would choose UHD as this is the standard for TV. DCI is true 4k but only used for cinematic recording, so I guess this means black borders on your 4k TV.
At least this is how I understood it, it does not mean it's right [emoji317]

I see a lot of people saying the same but for the life of me I just can't understand why. In the future when you have a UHD TV would you not want to see your recordings in UHD instead of HD?
I don't have a UHD TV yet but I do have a 4k TV but I would always record in the highest quality I can.
Btw, right now UHD seems to be broken.

That article's stupid. Plus it's three years old. I don't care how intelligent the author attempts to portray himself as by quoting a lot of math, I can and do see a difference between 1080P and 4K on a standard size tv screen. What a load of rubbish.

Another load of [email protected] from CNET. Anyone that looks at the two screens beside each other can see the difference unless your eyesight is bad.

Strictly resolution wise I see no difference. You may see other differences in terms of brightness and color reproduction but you can get that on newer or higher end 1080p displays.
BTW, the article was updated in May 2014.

I take it you own a 4K TV?

Random question on screen resolutions.

I'm just curious and I think I know the answer but I'm watching a "720p" movie on a qHD phone connected to my 1080p TV, which according to it only supports MHL out in 720p. Am I watching the movie in qHD b/c it's on my phone or 720p because it's on the TV as well?
Sorry if that was confusing.

You are watching at 720p as your phone won't upscale the image

Do you prefer 4K 30FPS or 1080p 60FPS video?

I'm personally leaning towards the 1080p 60FPS video from my brief tests. It's SO smooth. I wish we had a 4K 60FPS option...
What does everyone else prefer?
I would record at 4K 30fps over 1080 60fps because 1080 60fps is blurry compared to all other modes. I personally prefer 1080 @30fps because i dont have any 4K compatible tvs or computers.

I've never noticed blur. Did you notice on the phone or when viewed on a larger screen?

On the phone for sure, I haven't looked on a larger screen lately as I sent my phone to google on an RMA. I get the new device in a day or so so I'll have to look then.

I do lol thats why I use 4k cuz i can zoom without messing up the video quality
Either way, 60fps makes me want to barf and looks too fake. Like when people use the 120fps filter on their TV's. I think with free storage, may as well use 4k @ 30. Although, I feel the image stabilization is stronger @ 1080

How to play youtube videos at 4k 60 fps?

Youtube even on wifi only plays 1080p 60 fps max. There used to be a way to unlock this on older phones.
Is there any way to do it on the N20U? Links if needed?
If your on 120hz refresh rate then the screen is limited to 1080p. I only see the 4k option if I set my screen to 2k resolution

Question 1080p 60 frames softness/blurry

Hi, just want to find out if the ultra users record fhd at 60 frames with video stabilization on? I have done this twice now and the footage really isn't any good. The center is nicely focused, but to the sides it looks very soft/blurry. in 4k it looks great, but I stream the videos via wireless to my tv and with the 4k there is too much buffering...fhd streams fine. converting the videos from 4k to fhd seems a waste of time as it takes really long on my old pc. At this stage I feel it's almost worth the effort to convert the 4k to fhd to stream as there is such a big difference on the phone between the 4k and fhd. I don't understand all the technical jargon regarding 4k/resoltion etc but how much do I loose quality wise converting from 4k to fhd? The videos I take is from my daughter doing fast action sports(netball). The footage is in daylight with a lot of sun. Even the picture I take while recording is okay and some is blurry/double image, exactly like in the video. The attached shows the blurry effect...it's not motion blur, as per attached they were basically standing still. I use the dji mimo app sometimes and currently it only supports fhd 30 frames. The quality is much better via the app then the standard camera app
Anybody that has an opinion?
