Windows 10: Unable to connect a 1080p external monitor with a 4K UHD laptop.

I am experiencing a very weird problem. I cannot connect my 4k screen laptop with 1080p external monitor. I have 2 laptops currently both with 4K and touch. One is Dell Precision 5530 and the 2nd is HP envy 15 both laptops are running on windows 11 with all the latest updates and patches.When I connect my laptop with an external 1080p monitor I have 2 monitors, Lenovo and Dell with HDMI or type-c it just doesn't detect the monitor and also monitor shows "no input signal from HDMI" whatsoever.

4K monitor displaying from 1080p laptop

Hi I have a quick question (hope this is the right category). I recently purchased a Dell 4k monitor (P2415Q) to use on my Asus 1080p laptop. I did noticed that I was able to stream 4k video online fine (extended display mode), however I will be using the
4k display mainly for photo viewing/editing. Because my laptop is 1080p, does that mean the default windows 10 Images software will display my images in 1080p format? Or will it convert to the 4k due to the monitor? After trying to research this question online
I just got all confused and am probably overthinking this question. Thanks!

 

1080p Laptop Sceen to 4K Monitor

Hi All,

I recently updated to a 4K Monitor which i have attached as a second display to my Alienware 1080P Laptop.

I have noticed at first setup that the 4K monitor has everything so small due to its DPI advantage but its unreadable.

If i change the resolution to 125% .. 150% the screen becomes blurry.

If i change the main display to my Monitor it becomes crystal clear at 150% but my laptop screen becomes blurry and zoomed in.

any help would be great.

Thanks

 

4K and 1080p monitors

Hello everyone,

I have a question regarding the different resolutions of computer screens. I have laptop with a 4K display and I have a 1080p monitor. Most applications that I use tend to scale correctly when I drag them across displays. However some applications like IDLE
or Corsair UE don't tend to change their resolutions. They tend to stay the same when dragged to another display, so if it started on the 1080p screen it would go to really small and stay small on the 4k display and if I drag it from the 4k to the 1080p display
the application is massive and can't be viewed. Is there any possible shortcut which can be used to "refresh" the application without quitting and re-opening?

Thanks in advance,

.
