This review is from: TP-LINK TL-PA4010KIT High-speed AV 500Mbps Nano Powerline Adapter Starter Kit
Pros: 1. My house is pre-wired for internet, but I'm using those wires for so many things I (telephone, TV, internet) just need more wires! Transmitting the internet over the electrical wires would have been a great solution.
2. Apparently, you can use more than one pair of these in your house.
Cons: 1. Doesn't work with surge protectors
2. Seemed to interfere with the rest of my network
Other Thoughts: 1. At first, I couldn't get it to work at all, and I then had the idea of bypassing the surge protectors which I use throughout my house because of lightning risk where I live. After removing the surge protectors on both sides, it finally worked, but not totally reliably. Not being able to use surge protectors is a drawback.
2. I have a router hooked to a switch with my printers and several PCs hooked to it. When this TP-Link device was plugged into the switch, I lost internet connectivity on one of my PCs, and I unplugged and plugged back in the TP-Link, the internet connection was restored. I later tried to print something, and the printer didn't work. It appears that my network doesn't work properly when the TP-Link is hooked into it.
3. This device comes with a CD with software on it. The software apparently is not necessary to run the device, but it allows you to, among other things, update the firmware on it. I installed the software and tried to update the firmware, but it was asking for some numbers (NVM and PIB) that I was not familiar with, and the documentation provided didn't discuss it. I found a more detailed user guide on the website, but it didn't clarify at all where to get those numbers. By this time, I'd spent quite a bit of time on it and just gave up. I'm returning it.
This review is from: Diamond BVU195 USB Display Adapter (DVI and VGA with included DVI to VGA adapter)
Pros: --This doesn't require a PCIe x16 slot--just a USB slot. A big advantage if your PC has only one PCIe x16 slot.
--Works fine for most applications except TV.
--Works fine on multiple monitor installations
Cons: For TV viewing, picture quality was jumpy/jerky, and the aspect ratio was off
Other Thoughts: It works, and was easy to install. You install the driver from the CD, and then plug one end of the device into your PC’s USB slot using the provided cable, and plug your monitor/TV into the other end of the device (those cables are not provided). The device has a DVI output, but it comes with simple adapters to convert the DVI to HDMI or VGA.
I tried it out on a PC using Windows 7. In Windows, when you go to Control Panel->Display, you can adjust the # monitors displayed, etc. I had no problems switching between the Display Adapter monitor and the other monitors I had installed—it works just as if another video card was installed.
I have a PC that has only one PCIe x16 slot, and there are times when I really wish it had another, as the one slot is used for the video card. Using this devices will allow you to get video through a USB slot, thereby freeing up the PCIe x16 slot for something else (including, for example, a second video card).
I was hoping to use this adapter to watch TV with Windows Media Center. I found the picture quality to be good, especially for fixed images, but I had two major issues watching TV on it. First, when I watched Bloomberg TV on it with scrolling stock prices across the bottom of the screen, the scrolling stocks prices were jumpy/jerky. The other video card I used didn’t have this problem. Second, the images were not in the proper aspect ratio (i.e. they were too wide), and I didn’t see anything in the software to adjust for this.
So, depending on what you plan to use this product for, it may or may not work for you. As I was planning on watching TV with it, it didn’t work for me, but if you’re just using it for a PC monitor, it would work fine.
I’ve seen various USB->HDMI converters. This one uses USB 2.0 (and the PC I tried it on only has USB 2.0). I’ve seen other such converters that use USB 3.0. Since 3.0 is so much faster, I wonder whether the problem with the jumpy screen would still be a problem with a converter that uses USB 3.0.
Pros: Once I figured out how to install it, it works as expected
Cons: I purchased a refurbished unit. It did not come with a manual or the installation CD, which even though it is "refurbished", I would expect these, or at least some indication that I should download these online. Instead, the hardware only arrived in a box, and I went through considerable trouble to get it to work until I discovered that it needs software to be installed with it. I went to the manufacturer’s website and downloaded it and finally got it to work. This should never happen. At least, if a note was included that I needed to download the manual and software, that would have been better, but I’m very upset with this “refurbished” unit.READ FULL REVIEW
