Monitor unable to display at max resolution in some circumstances
Acer H243h Monitor Manual
- If I start or restart the computer without opening up the computer, I don't have the options to adjust the monitor to its max.
- If I open the laptop computer - now using both displays - I CAN set the monitor to its maximum
- If I then close the computer, the monitor maintains its maximum settings
- When I reboot, this process repeats again
I use Vista Home Premium 64-bit
The monitor's max settings are 1920x1080/75Hz.
The laptop display's maximum settings are 1440x900/60Hz.
I've toyed around with settings in Vista's Display Settings Control panel, the Intel Graphics Media Accelerator for mobile Control Pane, and the Acer eDisplay Management utility. I've tried these with the computer open (using both displays) and with it closed.
Quite honestly, it became confusing and overwhelming trying to track what happened differently in each scenario with different settings.
In the end, I simply have the problem described above - I can't get max resolution or refresh rate unless I first open my laptop - which is inconvenient in my setting.
Should I have to do this? This is the first peripheral monitor I've ever used with a laptop, so may it's normal?
I've attached a PDF with screenshots that I think will be helpful.
BTW, Acer's tech support is useless. First, it's extremely difficult to find a Web location for their USA support. When I finally did (through archive.org, I think), the support analyst and I carried on an email conversation. After much elementary troubleshooting and bad advice, he actually said to me 'Acer technicians cannot know about all of Acer's products.' And that was the close of the case!
Thanks for any help you can provide!
