Yes, I experienced the power-saving problem when the LG was connected via the DVI-HDMI cable. I am very happy to hear that your LG is working without a problem for you. I wish I can say the same. I returned the LG unit and am still looking for a 1920 x 1200 external monitor. I might instead go with two 1600 x 1200 monitors instead. :-)

On another note, the power saving problem has come back and after several reboots the monitor does not want to work. Even though the price was great, I cannot continue to deal with a monitor that simply does not want to work. Unfortunately, the 24″ monitor will be going back to Best Buy tomorrow or sometime next week.

I am still in need of a solid 24″ LCD monitor and am currently researching HP’s w2408. The price is just as competitive at just $485 shipped. But more important than price, I will need for it to simply work and will complete its due diligence before I purchase it.

Please offer up any advice you may have if you know of excellent 24″ LCD monitors. Thanks!

Thank you for the detailed response. While I have not yet had a chance to perform the test that you have described, I did contact LG USA customer service today. They specifically stated that this model has an MVA panel. It is also listed as such at the LG Canadian web site: http://ca.lge.com/en/products/model/detail/lcdmonitors_l246wpbn.jhtml# under the specification tab near the bottom of the page. Its great that MVA technology is becoming so similar to S-IPS that it is becoming harder and harder to tell them apart.

Thanks for reading my blog! I’ll try to answer your question as best as I can.

LG Electronics procure LCD panels from several source, but mostly from LG.Philips LCD, a joint venture between LG Electronics and Philips Electronics. LG.Philips LCD is a In-Plane Switching technology house and makes most IPS panels in the world. Others such as BOE Hydis, HannStar, Hitachi and a Japan-based joint venture called IPS Alpha also make IPS-based displays.

VA-based LCD is manufactured by companies such as Sharp, Samsung, AU Optronics, Chi Mei Optoelectronics, Chunghwa Picture Tubes and others. Although the possibility of the LG 24″ LCD monitor having a VA LCD panel is there, it would be surprising. Although some sites report that the LG 24″ LCD monitor uses a VA panel, my personal test, which I will show you below, shows that that is not true.

A way of figuring out if you have a IPS or VA panel is to use a pair of polarized sunglasses, or any piece of glass or transparent plastic that is polarized.

Polarized sunglasses are great at blocking light that bounces off of flat surfaces (roads, body of water, etc.). The light is generally polarized vertically and what that means is that horizontal light, light that bounces off roads, etc., are blocked, removing a lot of glare and helping you to see better.

If you place a set of polarized sunglasses in front of the LCD, you should see the contents pretty well. If you tilt it 45 degrees (positive or negative), most TN and VA panels should turn black. Now, if you tilt it 90 degrees a IPS panel will turn black. This is based on my understanding of how liquid crystals are aligned and therefore how light is polarized for VA versus IPS technologies. Try it and let me know what happens with your LCD monitor.

Note: Some polarized sunglasses are not completely vertically polarized and may be off by a few degrees.

Are you sure that this LG monitor is S-IPS? There was a discussion at one of the Anandtech threads (http://forums.anandtech.com/messageview.aspx?catid=31&threadid=2135720) where a frequent poster thought this was a VA panel. I tried to find out more information myself, but could not confirm that it is indeed S-IPS. Are you able to provide any additional information?

Thanks,
