My home-made pc worked fine untill 1 day, suddenly 1 monitor only works with vga
I got a acer 23inch G246HL full hd monitor wich I use as my primary screen
Secondary I got a medion akoya p54010 hd ready as my secondary screen
Thirtly I got my samsung hd ready 32inch tv, wich is always connected to my pc but the display is always disconnected in windows since I only use it rarely
When I turned on my pc yesterday the login screen was suddenly on my tv ad my medion monitor was the second screen, my acer screen didnt work
I got 4 connetions on my hd6850 graphic cart, 1 hdmi, 1 displayport and 2 dvi
On the hdmi both my tv and my medion monitor work, when I startup my pc with 1 of these monitors and then connect my acer screen with the cable from the screen I booted with it gives a black screen but it does get a signal because it doesnt goes is power saving
For the displayport I got an active displayport to hdmi adapter, on wich also both my tv and medion screen work fine. When I connect my medion screen by hdmi and my acer screen to displayport with the adapter the screen is recognized by windows as pnp generic monitor if im right (im not sure) but wont give a screen, just black but again it does gets a signal
For both dvi ports i got dvi to hdmi adapters, most of the time none of my monitors work on these ports but sometimes my medion monitor and my tv do work but I get green lines through the screen while booting for a couple of seonds and when I start windows i dont have any problems
When i use a dvi to vga adapter my acer monitor will work on that but again I get green lines and now they wont go away
The acer monitor is working fine on another pc, I reseted the bios and reseted my acer monitor but it all didnt work
Sorry if my english is bad sometimes but im 16 years old and english is not my primary language
