hp 2710M Overscanning on HDMI.

‎03-27-2012 01:42 AM

Have had the monitor for over a year, and it worked great.  Got a new laptop.  Set resolution to the full 1920x1080, and the display overscans significantly on HDMI.  (lose the entire top bar on full screen apps, on the bottom, the start button is gone, on the left, all but a few pixels of the first column of desktop icons, etc...

 

If I want to see the whole desktop, I have to scale back to 1600x900 and have the usual black bars surrounding it.  At 1600x1050 (yes, its an option) I can see the top half of the start button, the right half of that first column of icons, etc.

 

The machine doesn't have an obvious place to tweak over/underscan.  (it does have a catalyst control center, but it in no way resembles the one shown in the FAQ page on adjusting underscan)

 

I can hook it up via the VGA connector, and get a correctly sized image, but the quality of their VGA port is crap.  (all sorts of artifacts that vary with the fan speed)....

 

Machine is a Sony Vaio S series 13.3.  (vpcsa4f6x to quote the system info)  It has a "hybrid" video system, a Radeon when you have a lot of battery, and the intel embedded graphics for "stamina" mode (yup, thats what the switch says speed/stamina).

 

Anyone know where they might hide the overscan control?

Ok it took a lot of poking around, but I finally found the stuff to adjust.  (look in a file cabinet in a disused basment....")

 

Control panel: Display resolution.

 

Set resolution to desired 1920x1080 and apply.  Then on that same window, hit the link: " Advanced Settings."

 

It will put up a hardware info window, with 6 sub tabs.

 

Click on "Intel(r) Graphics and Media Panel" tab.

 

Click on "Graphics properties" button at the bottom.

 

Will pop up another window.  Select "Advanced Mode"

 

Much more complex window will appear.  pulldown bar for "Scaling", chose "Customize Aspect Ratio"

 

Two sliders appear (one H one V)

 

55% worked for me.  (steps are 5%, and actually make a fairly small difference)

 

When you first open the "Intel(R)...." tab, the "scaling" will only offer the choices centered (was the default) and full screen (makes it worse).  If you then go thru their "advanced mode" app, the tab on the device window will change.  The pulldown will now just offer "customize" and there will be sliders there.  No, I don't know why.

 

enjoy, discovering this only cost me 4 hours of sleep.
