Hello,

 

I'm having problems setting my screen resolution. Here's the problem:

 

My main monitor is an HP Compaq LA2205wg, which has a resolution of 1680x1050. I've used this one for about six years now, and it always ran on 1680x1050.

Two weeks ago, I added a second monitor. This one, an Acer v196wl, has a resolution of 1440x900.

When I added this second monitor, everything went quite well. The main monitor ran on 1680x1050, and I could 'park' google chrome tabs on the smaller monitor. It nicely extended my screen.

 

That went well for a few times. Up until I started my pc up again, turning the smaller screen on first, and then the main one. Then my view suddenly had an 800x600 resolution. I tried everything I could, but eventually, I was forced to do a small system reboot to force it back to 1680x1050. That worked.

Since then I've been on a little holiday for three days, so today I started my pc up again. It, again, gave me an 800x600 resolution. I can't do a system reboot anymore, because it doesn't have any backup points before this happened.

I can set the resolution on 1600x1200, but that's not what I want. Besides, the smaller monitor won't work on that set resolution (and it does on 1680x1050).

 

So what can I do about this?

I have an HP Pro 3400 Series MT desktop computer, with a built-in graphics card. Windows 7 Professional.

You don't make any reference to the interface(s) being used.  Adapters and converters are the worst approach as some units and cards do handshaking with the monitors and if either has defaulted to a factory setting, when the system powers up, it would get clues as to what resolution to use.  Interfaces need to be fed directly without adapters, converters or adapter cabling as many don't have the handshaking ability or is not supported by the mfgr.  Combinations of any two of VGA, HDMI and DVI work well.

I'm sorry I don't follow you that well. What interface(s) do I need to reference?

 

One has a VGA cable from the monitor to the pc, the other has a DVI cable.

Solved: it was a problem with my graphics driver.

I suggest if Windows Update is set to allow Windows to update drivers for you, consider changing this setting. It is a cause of random driver problems, when Windows finds an "update" and installs a more recent generic driver that doesn't work as well as the specific manufacturer developed driver you already have.
