i got a different graphics card for my pc and to use a dual screen set up , i had to buy a HDMI cable due to the card only having 1 dvi and 1 hdmi port. for the dmi i use a vga conversion , when i plugged in my hdmi cable to my card the resolution for the connected screen looks really low, even though it says its 1920x1080p , while my vga connected screen is perfect. i done a couple of searches to try and fix this problem and found a couple of things to try , none of them worked though. i tryed to change the pixel format , nothing happened. another thing that occured too was that there was an inch boarder around my screen, which i kind of fixed with image scaling in AMD Catalyst Control Center .

 

really need help to fix the resolution , thanks in advance 

my graphics card is an ATI AMD Radeon HD 5670

 

another thing that keeps happening is the screen keeps flashing, either when i open a new tab or type something.

Does your current Power Supply meet or exceed the minimum recommendations?

Expand the footnotes section and read #9. You may have to toy with customization.

Another consideration is try a different HDMI cable. Not all DMI cables are the same.

By that I mean... Cost does not play a factor but Quality od Construction really do!

got the problem fixed, i bought a hdmi to vga converter (originally tryed to use a hdmi to vga cable) . now my problem is that 1 of my screens flicker every now and then, tryed changing refresh rates to see if it fixed it but it didnt :-/ .

i watched a youtube vid and there was something about flashing the vbios, but im not sure if i should do this. anyone got ideas on what else i could do to try and fix it?

Your problem could be similar to this thread but of different hardware setup.
