Hi. I'm coming with a technical question that seems to be quite easy to answer. I have Samsung SM2443BW 24" 1920x1200 screen. The problem is that since I bought it on the net one day, DVI port is not working, almost at all (VGA is OK). What is the problem? When you power up your PC while monitor is connected with DVI cable, system is starting and on the screen nothing happens. I have also one ASUS monitor and it's working good on these DVI ports and cables, so my PC or wires failures are totally excluded. You may think: "you have destroyed DVI input in your screen", but I have excluded that too! How? When I disconnected ASUS' DVI from an GPU input and connected Samsung's DVI cable the same place, desktop was displayed correctly, but was stretched with 1280x1024 ASUS' resolution. There is the question: is it somehow possible to load fresh screen firmware without changing any parts? Can you predict based on your experience, could that be only screen software problem? Computer specification: GPU: AMD Radeon HD5850 CPU: AMD Phenom X4 955 Mainboard: Gigabyte GA-790XTA-UD4. RAM memory: Patriot DDR3 2x2GB. Tested on Windows 7 and Windows Server 2012. Thank you for all opinions about that.
