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 – Ramhound Sep 14 '17 at 22:15
  • "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 Sep 14 '17 at 22:23
  • @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... – Pavel Basha Sep 15 '17 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 Sep 15 '17 at 18:34
  • @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... – Pavel Basha Sep 16 '17 at 12:53
