New Graphic Card: Extended Display Problem
Hi,
I have Acer eMachines EL1352-215S7 and recently installed GV-R455HM-512I graphic card to enable using dual monitor. But, I can't choose extended display in my display setting. From CCC, no option for extended display only duplicate or single display. I has downloaded and installed latest driver but the problem still exist.
Then, I changed to another graphic card SAPPHIRE HD 4350 512MB DDR2 PCI-E which proven installed at another computer and has extended mode. But, after installed in Acer eMachines EL1352-215S7 the same problem still exist.
Please help and thank you.
