Duplicating 1440p monitor onto 4k TV - What will happen?

[akjoltoy]

I want to duplicate my monitor onto a TV. I wish to run the monitor at 1440p.

What will happen when I duplicate the display to a TV.

I know if the TV is 1080p, it would downgrade my monitor to 1080p

If the TV is 4k, will it downgrade the TV to 1440p? (this is what I want it to do, I just want to make sure this is what will happen, without any problems or forcing to have to have the monitor go below 1440p or something)

Displays always downscale to the highest common resolution of the two panels. In this case it should be 1440p, so I imagine you'll be fine unless your panel is designed by one of those bizarre no-name companies.

IF tv supports 1440 then its all OK, if not you could set your GPU to upscale the image to 4K for the tv
I use this for my 2560x1080 monitor with games that dont support this resolution (like DOTA!)

How would that work?

I'm duplicating the monitor to the TV. Duplication always uses the lowest resolution of the two devices

Your OP isn't very clear, but it sounds like you want to use NVIDIA's Dynamic Super Resolution feature or AMD's equivalent (please fill out your specs) to view a 1440p desktop on a 1080p TV while having a true 1440p display connected at the same time.

I guess it might be doable, in which case your monitor will be driven at a 1440p resolution while the TV would be running at 1080p with DSR active. You would of course lose clarity and detail on the TV.

You just have to try it and see - don't be afraid to experiment. This is what being an enthusiast is all about. You won't break anything and at most you just won't get a picture on one of the displays.

So, set the driver to duplicate the 1440p display onto the TV with DSR active on the TV, if it allows you.

Let us know how you get on.

Nope, his TV is 4K, and his PC monitor is 1440p. He wants to know if his TV will downscale to 1440p to match the monitor res.

Ah ok. Short answer is yes it should.

Yes sorry. I'm a bit scatterbrained atm and my post was unclear.

Wanted to know if it will display 1440 on the 4k TV. I know 1440 isn't a factor of 2160 and therefore the downscaling wouldn't be perfect but probably ok.

I was going to get a 1080p TV until I found out that it would force the monitor down to 1080p as well.

Sure you can have different resolutions!

I don't understand why others are saying otherwise. This is done all the time with notebooks when used with external monitors and projectors and when two different size monitors are used on PCs.

To be sure, Windows as far back as XP easily supports this. So does Linux. And it is even easier to setup in W7 and later. And most most graphics card drivers easily support this too. NVIDIA Control Panel with my GTX 650Ti does. Again, not sure why others are saying otherwise. A quick Google search shows people do it all the time.

There are also several multi-monitor utilities that let you easily manage multi-monitor setups. My favorite is UltraMon – not free, but worth it. Others have suggested the free DisplayFusion, but I have no experience with it.

See also, Dual monitor setup is easy in Windows 7! and Ask Leo! How do I get my two monitors to display at different maximum resolutions?

So I say try it and see what happens. No harm will be done.

You can enable scaling on the graphics card menu on most computers and then the graphics card will scale it for you and you won't have to worry about whether the TV supports 1440p or not

Might be an issue if the TV only supports 30hz and the 1440p monitor does not support 30hz

Hey don't worry about being scatterbrained my friend, especially when I'm off work with the flu like now and find it hard to think in a straight line, lol. I know where you're coming from.

Assuming you're using an NVIDIA graphics card, then the driver has various scaling options. The basic two are that you can either have the 1440p resolution shown in the middle of the screen with borders all around, but at a nice, sharp 1:1 pixel mapping, effectively at native resolution of your 4K TV, or have the graphics card scale the picture to fit the screen, with all the aliasing and blurring artifacts that would bring. I would prefer the former, but it's ultimately your choice.

AMD cards can also do this, but I don't have one so couldn't give you screenshots if you get stuck.

Also, as Bill said, you can have the TV and the monitor both running at their native resolutions with the extended desktop feature of Windows. How you set it up, totally depends on what you want to do, there's no right or wrong about it.

Just to repeat, please fill out your system specs as it looks cool and helps us to help you better, plus you can't break anything by experimenting.

Thanks for the help everyone. I ordered that 50" 4k Vizio on Amazon during prime day ($780)

Going to be duplicating my 1440p monitor onto it for watching stuff and for gaming. Going to be sick.

Just a point I'm sure you know, but if you duplicate it it won't be in 4k, It'll be in 1440p on both monitors

Yep. Primary concern was "can the TV display 1440p" which I'm pretty sure it could

However the question became moot because I decided everything would be much better if I:

-put 4x Titan X's in quad-SLI
-bought a 4k monitor

I was about to open up the 4k tv and fuck something up inside so I could get free return shipping. But then I figured I'd just go this route. Lucky for Amazon haha

Anyone here have a problem with the fact that I was ready and willing to do that? I'd love to hear your thoughts

Four Titan X's? Woa, besides costing the earth, you'd be better off with one of the faster 980s out there which are actually quicker and quieter than the Titan X as well as costing much less. Check out TPU's reviews, as I'm sure they've revewed one or two of them.

So yeah, it's dishonest alright to break the TV for a refund, but I'm not going to have a problem with you doing it. Do you not have the option of returning it for a refund without breaking it then? I'm thinking that if you bought it online you could do that within a limited time. Also, if you break it, watch out they don't call you out on it, as you could then be out of pocket and out of TV.

I have a problem with your attitude. Not to mention the fact that what you're explaining is illegal, and has no place on these forums. You'd do well to keep that in mind if you intend to remain here.
