Hi All,
I have purchased a new 4K TV but my laptop is not providing a 4K Resolution through HDMI. Can Someone Please recommend the cheapest laptop which provides 4K Content through HDMI?

Thanks and Regards,

Otherwise is it possible to add something to my laptop which upgrades my laptop to provide a 4K Resolution through the same....

What is the make/model of your current laptop?

Your laptop should be able to support 4K displays. See page 65 of the laptop manual.

Are you using a quality HDMI cable?

Your laptop should be able to support 4K displays. See page 65 of the laptop manual.

Assuming the OP is wanting 4K @ 60Hz, HDMI 1.4 is unfortunately unable to do that.

Understood. Not exactly clear regarding desirements from initial post.

The laptop is capable of pushing 4K. What resolution is Windows setting for your display?

And what happens when you select 4096x2160?

Which exact TV model do you have?

If I had to guess, the reason you're getting those notifications is that your laptop can't output >1080p at 60Hz. It may think that 1080p/60Hz is more "optimal" than 4K/30Hz for whatever reason.

Also note that your TV supports 10 bpc color, but your laptop can only output 8 bpc color at 4K/30Hz. Unless you turn on chroma subsampling (to 4:2:2).

Your laptop has HDMI 1.4. Technically your current laptop can do 4K/60Hz, but only at 8 bpc and 4:2:0 chroma subsampling. I'd imagine these settings would be in your Intel graphics settings somewhere, but I don't know where.

You could upgrade to get HDMI 2.0 if you want. To get it:

For Intel, look for any of these CPUs or these CPUs. Note that the ones in the first link are very weak/low power CPUs.

For AMD, any "Ryzen" chip will do, or any "Athlon" 2[xx]U or 3[xx]U.

That's for laptops that only have integrated graphics, which are usually the cheapest. I'd think just about any modern laptop with a discrete GPU would support HDMI 2.0.

Note that even HDMI 2.0 would still need 4:2:2 chroma subsampling to get 4K/60Hz with 10 bpc color (8 bpc requires no subsampling).

Yes, it is possible to connect a graphics card to a laptop using an external adapter. You would also need a power supply for the graphics card.

What is a Graphic Renderer? and why can't we use that Graphics Card for windows resolution and performance? Please reply

I'm not sure what you're referring to.
