From the base spec:

 

https://psref.lenovo.com/syspool/Sys/PDF/Legion/Lenovo_Legion_5_15ARH05H/Lenovo_Legion_5_15ARH05H_Spec.PDF

 

"Max resolution: 4096x2160@60Hz (HDMI); 3840x2160@60Hz (USB Type-C)"

Interesting. So HDMI 2.0 output via port so I assume it supports 144hz but spec sheet pdf does not state so. 

So are you thinking that it could actually run a 4k monitor?

 

I also read it will lower the fps to 60fps at HDMI 2.0 per the below but I will not be gaming.  And the limit might be 120hz or actually less with HDMI 2.0 assuming it goes that high.

HDMI 2.0

HDMI 2.0, referred to by some manufacturers as HDMI UHD, was released on September 4, 2013.
HDMI 2.0 increases the maximum TMDS per channel throughput from 3.4 Gbit/s to 6 Gbit/s which allows for a maximum total TMDS throughput of 18 Gbit/s. That allows HDMI 2.0 to carry 4K resolution at 60 frames per second (fps).

Other features of HDMI 2.0 include the options of the Rec. 2020 color space, Dual View, 4:2:0 chroma subsampling, 25 fps 3D formats, up to 32 channels of audio, up to 1536 kHz audio (for example 7.1 channels of 192 kHz), up to 4 audio streams, 21:9 aspect ratio, the HE-AAC and DRA audio standards, dynamic auto lip-sync, improved 3D capability, and additional CEC functions.

HDMI 2.0a was released on April 8, 2015 and added support for high dynamic range (HDR) video.
 

 

Thank you

Peter

So I guess the real world question if you can actually find it besides the PDF (thank you) is does the HDMI 2.0 output of the laptop

(assuming it is 2.0) support 2k and 4k monitors  albeit perhaps at a lower hertz and frame-rate?

 

 

And if you were buying a monitor would you stick with 1920 x 1080 or step up to 2k?. I think 4k would be too costly for me at this time and I keep laptops for at least 4 years. My current one is 8 years old.

 

Thank you all

Peter

External display will absolutely support higher than 60hz, you just have to set it up in Windows as an extended display (it's own screen). If you mirror the primary display then you will only get whatever the lesser monitor supports

Well with the laptop (Legion 15 with 1660ti graphics) it is 144hz laptop monitor so duplicating or mirroring should be ok I assume. However when I did this the new monitor I tried , Benq XL2411p, it only received 60hz and not higher. Could not change to higher resolution. Perhaps because I had an HDMI cable (do not know if 1.0, 1.4, etc..) and did not use DVI or displayport.  Am returning monitor anyway as it seemed washed out with respect to colors. Perhaps because it is a TN panel.

 

Tx, Peter
