Maximum resolution of external monitor

[Steinello]

HP Laptop 17-cn3454ng (PN: 9P6F2EA) SN: [Personal Information Removed]

Hello,

I tried to connect an external Monitor over HDMI - but the highest Resolution is FullHD (1920x1080).

The HDMI-cable is correct - the Resolution of the intended monitor is 2560x1440

I checked the Bios - there are no further updates with HP Support Assistant

I also tried the newest Intel Graphics driver.

The external Monitor scales to FullHD

Kind regards

Thomas

Its specs

It has  (1) HDMI v1.4b port (out). In theory it supports higher 1920x1080 resolution but many HP machines support FHD only

Regards.

... that's a yoke that a new Notebook only supports FullHD 

... If I look into the specifications of HDMI 1.4b I can't see any reason why there should be a restriction to FullHD

I did say that  (above) with HDMI 1.4b. Sometimes we have to live with people jokes.

... thank you for the reply

... but I can´t find any information about the FullHD limitation (e.g. Specs)

... sorry, but nevertheless there should be a information about this restriction

Kind regards.

I found a solution for my friend.

With a USB-A Docking-Station I can select a higher resolution (only over the right USB-A Port)

--> Problem solved !

the real specs:
- 1x USB-C 3.0 (5Gb/​s) <-- no Video-signal
- 2x USB-A 3.0 (5Gb/​s) <-- Video-signal only over the right USB-Port !
- 1x HDMI 1.4b <-- only FullHD

Infos over the original HP Specs:
- 2x USB 3.2 Gen 1,0 Type-A; SuperSpeed 5 GBit/s (an jeder Seite einer)
- 1x USB 3.2 Gen 1.0 Typ-C, SuperSpeed 5 Gbit/s (nur Datenübertragung; Aufladen oder externe Monitore werden nicht unterstützt)
- 1x HDMI v1.4b-Anschluss

... it´s only a consumer-product but I think it´s a shame for HP ;-(

It's good to know you have a work around but just FYI, HP says

          High-definition multimedia interface (HDMI) v.1.4b supporting up to 1920 × 1080 at 60 Hz
