My K242HL has too wide a picture. Circles look like ovals. Resolution is fine.

After working fine for 3 months my monitor changed to the 800 x 600 resolution which is way too big. I got it changed back to 1600 x 1200 so it is OK. 

However, I now have a new problem with the display proportion. The picture is too wide but otherwise fine.

Hello,

 

Look at this Microsoft topic.

Thanks for the reply.

I forgot to mention that I am using a Macbook Pro. It worked fine with this monitor and a previous Acer monitor.

The K242HL has a native resolution of 1920 x 1080, or a 16:9 display. This is the most accurate, sharpest resolution to run in. Every display panel has a native resolution which can differ from model to model. Unlike a tube monitor, on a display panel, each pixel has a physical set of dots, and the display makes a best effort to spread the picture across dots when you use a non-native resolution. This can lead to display artifacts, where the picture does not look 100% steady.

 

If you are running at 1600x1200 (UXGA), you are under on the horizontal (width) and over on the vertical (height). Running at any other ratio (1920 divided by 1080 gives a ratio of 1.77 repeating) will give you squished or stretched circles (as well as everything else. You are running a ratio of 1.33 repeating, which is why it's all out of whack.

 

If you cannot run at 1920x1080, you could run at 1600x900 (16:9 is 1.77 ratio) to get circles that are really circles. Other common 16:9 display (aka 1.77 repeating ratios) sizes are 1366x768, 1280x720, 1136x640 and 960x540. Any lower resolution, and you might as well stack LEGO blocks for a display (even those low ones are pretty blocky). Simply take the first number and divide by 1.77 and you should be close to what you should set the second number at.

 

Hope that helps!

Yes.

I needed to get an HDMI cable and then it worked.

Thanks,
