Hi everybody, I bought Sapphire Radeon HD 7750 800Mhz 2048Mb 1600Mhz GDDR3 128 Bit HDMI DVI-I VGA PCI-E adapter to use Ultra HD (4K) monitor. I use HDMI cable to connection (dislpay port is absent in this adapter). But I can set 30 Hz frequency only with the Ultra HD resolution. I use Windows 7.

Is the point in adapter or in slow PCI-E port in my mainboard?

And if adapter does not allow to reach 60 Hz, then why it is not reflected in documentation?
