Need in Help!
I have a new build: Asus P8P67 Pro Rev 3.0, Intel I7 2600K -not overclocked, 2x4G DIMM1: G Skill F3-12800CL7-4GBXH, Radeon HD5850, SDD FM-25S2S-60GBP2 (60 GB, SATA-II),Disk Drive WDC WD5000AAKX-001CA0 (465 GB, IDE),Monitor Name Iiyama ProLite E2607WS, Flat Panel: Sharp LC-52LE705E.
OS Version 6.1.7600 (Win7 RTM)

My old PC with the same Radeon HD5850 was working fine both in single screen config and in clon mode, so I was able watch movies from the old PC on big LC panel.

With the new build a single screen Iiyama ProLite E2607WS works fine , but any attempt to switch in clone mode results in black screen in both monitors and Win 7 is blocked: no mouse reaction, no keyboard reaction. What is strange that extendent screen mode works fine. Can someone help to solve the problem?
Thanks.

That would be a problem with the display drivers. Which version of the AMD drivers are you running? Update them to the most recent if they are older.
