Monitor driver confusion - Acer S243HL
I just bought a new monitor (the Acer S243HL mentioned in the title) to create a dual monitor setup with the one I already had (Lenovo L220X).
Since I didn't find any slots for the default cable that came with the monitor (HDMI unless I'm mistaken), I went through my hardware box and found an adapter that allowed me to finally plug it in (my graphics card is ATI Radeon 4850, or at least I think it is - 4800 series in any case).
Whether or not I used the perfect adapter, I do not know, but I was able to connect the monitor and finally turn it on, which was a great sigh of relief for me. Unfortunately, that's where I encountered my current problem: the OS (Windows Vista Ultimate 32) doesn't recognize the specific model, instead treating it as a "Generic Non-PnP Monitor" (with the maximum resolution of 1600x1200 - not quite its native 16:9 1920x1080). The box it came in contained a CD, but I was able to find only manuals and an application for calibration and specific adjustments (called ADM - Acer Display Manager) - no drivers.
That's where I used Google to locate and download the appropriate set of drivers on Acer's support page. After installing them (version 188.8.131.52), the monitor was listed properly listed as "Acer S243HL" and I was able to increase the resolution to 1920x1080, but that resulted in intense epilepsy-inducing flickering (which could not be remedied by increasing the refresh rate, because that was now locked at "30 Herz, Interlaced" - the only option available was to further lower it).
Also, Acer eDisplay Management (the latest version, which I downloaded from the official site in the meantime) doesn't even recognize the monitor, regardless of whether it's set to primary or secondary status, so I can't change any options there. I don't know if it has any bearing on this situation, but my other monitor (the L220X) has a different aspect ratio (16:10, with a native resolution of 1920x1200). Could that have anything to do with it? Am I using the wrong adapter?
I'm a bit puzzled, especially since I wasn't able to find any existing threads dealing with similar problems with this model. Any thoughts?
I'm not sure if this is the ideal place to post this, so if any of the mods feel it belongs elsewhere, by all means move it. :)
