Monitor cannot connect to PC

[DduckK]

Hi guys,

Today I bought a new monitor - LG 20EN43 but the problem is when i plugged it to the VGA (gigabyte gtx750ti) through DVI port, it showed this(pic). I tried many times and sometimes it could work for a while otherwise it showed the same. I plugged it to D-sub port on mainboard, it worked correctly. Addition: This monitor only has D-sub port so that I have used a D-sub to DVI converter

Sorry for my bad English. Please help me

Plug the monitor in to the mainboard graphics, then adjust the refresh rate of the 750ti. It looks like it is refreshing at too high of a rate for your monitor. You can also keep the monitor plugged in to the 750ti and boot in safe mode and do the same.

Make sure your DVI adapter is a DVI-D Dual Link connector. If it is not then you may need to get one.
