No 42" computer monitors exist, and no TV has gsync (afaik)

There's your problem :)

What tv should I use for 4k gaming in 42" then? Also will not having g-sync make a difference?

Personally I could never recommend a TV for gaming at all.  For one, there will be a noticeable (depending on the game type) delay between your inputs and actually seeing the change on the screen.  This is called "input lag" and is generally several frames worth @ 60 fps on a TV, but generally under 1 frame on computer monitors.  Second, you will be limited to 60 Hz since even the 120 Hz and higher panels that do exist use that speed "internally" and won't actually accept a signal higher than 60 hz (60 fps).  With computer monitors, you can go up to 165 Hz (I believe is the fastest right now).  Now, you probably won't be driving 4K at anything above 60 hz anyways, so that may not be a concern, but it's something to think about.

 

The purpose of Gsync is to vary the refresh rate of your screen with the output of your graphics card.  That means that if the GPU is putting out 43.7 fps, the screen will simply refresh upon receiving each frame, rather than at a constant 60 hz, which can cause tearing or stuttering trying to line up those numbers.  Bottom line is that gsync can make lower framerates look smoother than they would otherewise be, but if you can run at or above the refresh rate of the screen (60 hz for example) then it doesn't make any difference.

Thanks very much! That is some very helpful information! What is the largest 4k g-sync monitor you would suggest in that case?

I should ask, what are you thinking for budget?  Anything half decent is going to be a minimum of $1000 because of that size, feature set and resolution, almost without question.

I would rather save up longer and have a better product that will give me less headaches and has the features I want than buy something cheaper and have it tick me off for years.

In that case, I would take a look at Linus's most recent few "best monitor" videos.  They're expensive, but they're in his opinion the best gaming monitor you can get, period.  You'll notice that he's ended up leaning more toward ultrawide rather than 4K, for one thing.

ultrawide is 1440p then?

Depends; there is 3440 x 1440 (so yeah 1440p) and 2560 x 1080

Huh, maybe I'll just wait. My current 42" is 1080p and doesn't have any input lag that I have noticed. 4k sounds like it isn't supported by enough stuff yet and has a few unresolved issues in need of fixing. And I honestly feel like 1440p will be a shortlived and largely unsupported half gap between 1080p and 4k that won't ever have much time to shine and as a result will never get developed much.

Do a search for Wasabi mango, they do 42, 49 and  55inch 4k monitors with freesync. And the prices are not bad.

 

You can get them on "that bidding site"

I actually saw those on amazon but the product description says it can have up to 5 dead pixels and some light bleeding. So I'm thinking I will wait until I get one that has better performance.
