StarTech.com 4-Port VGA Video Audio Switch with RS232 Control - VS410RVGAA | VGA Switcher for Multiple Monitors | Ideal for Conference Rooms, Home Theaters & Gaming Setups

I purchased this product and realized that I made a mistake on the item I ordered and returned it by refusing the package when it was delivered. After about 10 days, I got a notice in my e-mail from Amazon that they were crediting my credit card in full without any questions. I gave 5 stars for the service I received from Amazon.However, I do own 3 of this device for 9 months, and It's been working just fine as it should. I have them installed in my two different conference rooms to switch between many PCs and Laptops to two LG 55" LED TV/Monitors and a Mitsubishi 73" rear projected TV. The Mitsubishi TV did not come with a VGA connection so I even have a StarTech VGA to HDMI converter installed on top of StarTech VGA switcher, and they all work harmoniously without any comparability issues. The user manual from StarTech does not explain all the features in detail, but it seems to me they work bi-directionally, so the resolutions and format of the images on the monitors are all set automatically by the PC or the Laptop. Time to time when I do not like the format the computer selects, I change it manually, but this change is limited to the video card capability in the computer. Also, this is a true 1920x1200 resolution VGA swither.But, there could be an issue with this device one needs to think about. If your TV/Monitor does not come with a vertical and horizontal image location adjustment/control for the VGA (PC) input, the image may appear off center and part of the image will be covered up. This is not the case with HDMI input. Fortunately, my monitors came with the control, but I had to call the service department of the TV to find out where that adjustment was. It was in "Setting" section of the TV control menu under PC Input.So, I have no idea when the others complain about this device. I give 5 starts for this VGA Switcher too. And, thank you again AMAZON for such a generous service.
