Hi, I am really need help. Trying many ways but nothing helps.
My laptop doesn't recognize my external monitor.
I was trying to connect monitor to my friend's dell laptop (he have smaller laptop, but very similar with mine) and all works just instantly after connect.
At the same time, on my laptop external monitor was work after many actions with drivers, uefi, etc. And in the end I don't understand what factors can help me in past to connect with monitor. But I can say, that external monitor works at first time after install drivers and rebooting pc, I think.
Recently I reinstall my operating system and trying to connect external monitor again - as I expect - laptop doesn't recognize it again. To resolve it, I am install the drivers, trying actions, that helps me, how i think, in past. In the end - nothing works and laptop doesn't recognize the external monitor again, like in past.
All characteristics that can help are below.
Laptop - Dell Inspiron 17R 5721
Motherboard System - UEFI A14
Video Cards
Integrated - Intel HD Graphics 4000
Discrete - AMD Radeon HD 8500M/8700M Series (Mars)
External Monitor - IIyama Prolite XB2483HSU
Connection between laptop & monitor - HDMI-HDMI
My Thoughts
I really don't understand what happens. In past I have the experience to connect different laptops and external monitors and always it was very easy. Just put in hdmi cabel and all works! I can't understand what's wrong with my laptop. Even my friend's almost similar laptop works with my monitor easy just after put in hdmi cabel. I thinlk, may be problem created by new uefi system or something wrong with drivers and I need some unique drivers for my graphic cards (I am already trying different drivers and ways).
If someone know how to resolve this problem - please, help.
