Hello, your motherboard supports the latest HD4000 core display. If you use HDMI, have you adjusted your display? The display has a special HDMI mode,When HDMI is converted to VGA, there is no transfer line for a digital signal or an analog signal. The market is full of lies. I suggest you adjust your display mode. I remember when I first contacted HDMI, I just didn't find the right mode. It took me a whole night to find out that the original HDMI mode hasn't changed. I said that it doesn't support integrated display, but he is eating Xiang,Z77, H77, B75, and H61 are all checked and displayed, and HDMI to VGA cable is not allowed. Remember, of course, personal suggestions are displayed separately. Between your U, I suggest GTX650TI, HD7870, and GTX580 (now it is very cheap, very affordable, 1500 public price, GTX660TI per second, you know, not necessarily the latest)
You need at least one 256 bit video card for this configuration, 2 types are recommended;Yingchi GTX 550 TI or Yingchi GTX 560 TI requires 256-384 bit width. The price of 550 is about 1100 - 560. The power supply of Gigabyte motherboard is much better than that of ASUS at about 1700. We are specialized in Internet cafes
The H77 motherboard on your U is enough. It is recommended that MSI ZH77-G43 motherboard be used. The Z77 is suitable for overclocking U use. There is no other problem. There is basically no compatibility problem. The total price is about 5000. Please choose a big brand for the power supply.
