Screen flickering. Tried everything. Please help.

Hi Everyone,

The second monitor I've hooked up to my laptop flickers for a millisecond every 15 seconds-or-so.

Monitor = http://www.hxlstore.com/43163671586.shtml
Laptop = Toshiba, Windows 8, 64, AMD A6-5600, Graphics card Radeon HD 8400 (400mhz)

The laptop didn't allow a 1920 x 1080 @ 60 hertz resolution to the second monitor. I used the custom screen utility (https://www.monitortests.com/forum/Threa...tility-CRU) to achieve it.

However, it now flickers.

- No way to disable EDID on the monitor
- Radeon control panel doesn't allow deselecting of EDID
- Updated graphics card driver and control panel with no luck
- Tried playing around with detail settings in CRU software with no luck.
- Updated the driver

Would love some help as the screen was a gift....

many thanks . simon
