Windows 10: How do I use my TV as a 4k monitor without Windows treating it as a large monitor?

I have 2 23" 1080p monitors and a 45" 4k TV connected to my computer. Whenever I set my TV to run at 4k, windows treats it as a 40" monitor and only allows the mouse to move between the monitors in a 1080 pixel window where it thinks my monitors are. What I want is for it to only increase the resolution, but treat it as a 23' 4k monitor. I have tried the scale option in Display settings, and it does not solve the problem.This is what it does when the TV is set to 4k:I want it to do;

Why not buy a small 4K TV instead of a large 4K monitor?

People do it.

Rule of thumb: if the spacing between the TV and the eye is about equal to the diagonal of the TV, the pixels will just be resolved by someone with good vision.

I suggest not getting an OLED TV because of potental burn-in issues. The smallest OLED is 55", anyway - a bit large for a desktop monitor.

 

Why not buy a small 4K TV instead of a large 4K monitor?

This question has been dogging me for years.

I'm a desktop PC person. I like having a desk, a monitor, and these days a smaller or 'Mini' PC nearby. 3 years ago I bought an Asus Vivomini PC and paired it with $329 2K 25 inch monitor. Something like this --





But now I ask myself, self, what if you upgraded to a significantly bigger monitor? Not for gaming but really so I had the room to leave more apps open and accessible all the time? The industry wants you to buy something like this --





-- for $499. But I'm like, wait, I can get a 4K TV set with ten more inches for less than half that price ($229) --





-- AND get a TV in the same room for 'free'.

HERE'S THE QUESTION -- Why wouldn't someone just by the 4K TV instead? Is there a spec thing I'm not considering? Is it that if I sat 3 feet away from a 4K set it would look all pixelated?

 

Want Large 4K Monitor (>48 inch) no TV tuner necessary

Hi there

would like to get a very high quality 4K monitor (>48 inch) that doesn't need a TV tuner but has at least 2 and preferably 3 HDMI inputs.

Most of the high quality 4K stuff seems to be TV's that can double as a Monitor, or the large ones that are monitors only seem capable of 1080p at max res.

Any recommendation.



Cheers
