I bought a new monitor for me - Dell p2416d with 2560*1440 resolution. I have laptop with Intel 4000 and AMD Radeon 7650M.

Problem is that I cant use external monitor in hight resolution. Only 2048*1152 is available. I already climb around all google but cant understand what is main problem.

I reinstaled AMD drivers. But it looks that max resolution of it is 2048*1152. But if look at description of this graphic card - max resolution is 2560*1600: http://www.gpuzoo.com/GPU-AMD/Radeon_HD_7650M.html

I use the HDMI v1.4 (4k*2k video support) to connect monitor and laptop.

How can I exactly find max resolution of AMD?

Information that AMD Catalyst Control Center gives: system info

Please, help me...

  • "How can I exactly find max resolution of AMD?" - You already know the answer to this question, it's 2560*1600, but you failed to specify the native resolution of the monitor

  • "Intel HD Graphics 4000 supports resolution up to 1920×1200 through HDMI" - Stop using HDMI if you want a higher resolution - superuser.com/questions/964703/…

  • @ramhound I had specify it: max resolution of monitor is 2560x1440. Today I tried this monitor with displayPort with another laptop.It gives me full resolution in this way (2560x1440)So, Is it mean than if I have only hdmi and vga at first laptop I can't to get higher resolution with this monitor? It's seems mystery because we know that the throughput of AMD Radeon 7650M is 2560x1600 and it has only hdmi... Sep 15, 2017 at 18:32
  • Sounds like the maximum resolution of that GPU, on the website you provided, isn't valid information if you don't have a displayport.

  • @ramhound it looks so weird.. you have graphic card that can give you 2.5 k resoluthion but you can't get it because you haven't displayPort... Sep 16, 2017 at 12:53
