Extended desktop problem -- i7 and Asus P8Z68-VPRO/GEN

Docus · 16 Mar 2012

Hello everyone,

I just finished putting together my first custom-built PC, using an ASUS P8Z68-VPRO/GEN3 motherboard with a 2700K CPU. For now, I'm just relying on the built-in graphics until the Radeon 7000 series are a little more affordable. I wanted to be able to set up a dual monitor configuration, so I purchased a couple of identical ViewSonic 22" VX2253mh displays, which are plugged into the motherboard with HDMI and VGA cables. After installing Windows 7 and downloading all of the updated drivers I could find for my chipset, the motherboard, and everything in Windows Update, I set about changing from a clone display to an extended desktop configuration. I got it working alright, but with one really annoying problem: on the monitor that is connected via HDMI, there is a scaling or resolution problem so that I can't see the edges of windows that are maximized. It seems to cut off around 20 pixels in every direction--so I can't see the menu bar in my browser right now, for example.

For what it's worth, when I use the Intel software to modify my display, it refers to one of my monitors as "Monitor VX2253 Series" and the other as "Digital Television VX2253 Series," and whenever I try to change the digital television to monitor, it automatically switches the other to digital television. I presume this is standard procedure for some reason, though it's confusing to me why they would automatically refer to my second monitor as a television...

OK, I actually just solved my problem. I'll go ahead and post this anyway, in case someone else stumbles upon it and finds it useful.

Solution: I just accessed the menu on my HDMI-connected monitor and played around with the settings. I noticed that for input, it listed HDMI -- AV. I changed it to HDMI -- PC, and voila! Dual displays are a beautiful thing.

function is disabled automatically to accommodate the image, horizontal and vertical disabled factory, a horror, hopefully the resolution will correct the image when you select the input type (menu input signal) on several occasions, if we are lucky the resolution is corrected. within the menu we also have disabled the function of digital TV and here comes trouble, I think it was a frustrated TV re-launched to the market as a monitor, depressive china_ company but that's not all, I have not tried the vga mode, HDMI mode also is wrong, has blackouts, perhaps the frequency of update, I by testing if you have more data will be appreciated, greetings from Argentina
