My laptop only has a USB 2 port. Will it work with USB 2 if I use the power adapter? If it works, is there a loss in video quality?

Hi, yes it will work, no matter how you choose to use it (only usb or usb+adapter) it will not affect the picture quality resolution wise. The difference in using the adapter or not is that when you use only USB the luminosity will be at 75%. By plugging in the adapter you will have 100%. If you plan to use it with the adapter you will only require one USB port. Hope this helps.Tiberiu

It works. Probably works better with windows before 8.1. Getting driver to install on 8.1 is a problem for some reason.This is a GREAT Unit however, small and great picture once you get it installed. Newer version of the machine are probably even better but this one works OK.

If used with the power adapter you get the highest lumen output which is the way I preffer to use it. You can power it off 1 or 2 usb to change the power output. The quality of the signal is the same on USB2 or 3 but the error rate will. Be higher on usb2 if watching fast action movies. I primarily use it for business power points and picture slide shows. There may be a better solution from other vendors if you are looking for a portable movie setup. 200 lumens and above will give you clearer blacks and higher contrast and colors that pop.I am satisfied with this unit for what I use it for.

It will work with USB 2, but won't always be up to the task for fast movement. Would highly recommend using the power adapter as that makes it the brightest, compared to all other configurations.

No. It's not a USB adapter at all, of any kind. It adapts a full size DisplayPort monitor plug to a Mini DisplayPort monitor plug. It won't let you connect anything to USB, despite the fact that Mini DisplayPort plugs look like USB.

However it works fine with a single USB connection as long as your PC or Laptop supplies the "rated" voltage and current for a USB 2.0. I've used ours for years on a single cable with no problems.... however your mileage may vary

This unit does need power adapter if your HDMI port doesn't produce a power source for it. I ordered it and was about to send it back but Amazon made it right by giving me a power adapter free of charge. This post needs to be changed because the information is incorrect and from my understanding Amazon is working on having this corrected for future buyers.

IThat'd the model I used it with. While it works, the external video only worked a prin of the time. It was so finicky that I abandoned this and more just use a usb hub with network adapter and hdmi to monitor. Cheaper solution that works all the time.

I use Taichi 21 it accommodates my large screen and laptop perfectly. I tink it should work with any laptop as you just download the right driver for both devices. Usb 3 is the latest technology and it is compatible with most usb 2 devices. So you don't have to worry compatibility. Brian

Hi Jennifer. I think it should work just fine. My laptop only has an HDMI port as well and this adapter works great for PowerPoint projectors and monitors. It was a convenient, low cost work around. Good luck!

Hello L. RobinsonBase on your question. I truly cannot answer it because; you have not provided enough information about your laptop, e.g. model or a given scenario on how you going to apply this device e.g. docking station or port replicator, if applicable. Second, upgrading a video card on a laptop is unlikely or unheard of to my knowledge; based on your question. Finally, this product, which you are inquiring about gets connected to a USB port and not a VGA port; based on your question.

I don't know. All I've used is the HDMI and USB, and have not had any issues at all. The other comment about the USB port being defective makes the most sense. I don't think VGA would deliver power -- I think that has to go through the USB connection.

It'll work as a standard 110v adapter I guess will do fine if your laptop charges over a usb, quite not common since laptops come with special power transformer adapter that goes straight to an outlet not via usb but you should know better how your laptop charges.Will do fine as a car or wall traveler and works with smaller devices as cellphones tablets iPods ipads that charges via usb. Really helpful to get rid of two specific chargers for each device thou.

It is not a usb adapter. The display port has become more standard on Dell pcs. You can still purchase a usb to video adapter but I would not recommend it.

This is not an adapter. This is a HD converter. I have a very old laptop without an HDMI port. This converts the signal to HD so I can use my HD TV as a computer monitor. If this is actually what you are looking for, it should work with all Windows OS's. I am no expert but I have Windows 7.

This used to work on Windows 8, but I tried to use it today on Windows 8.1 and the device driver no longer loads correctly. I tried contacting the company to see if they are coming out with a new driver. http://www.gearmo.com/shop/fast-usb2-infrared-adapter/

Cant exactly understand your question, if using without computer where do you take input signal from? This device has only VGA input (no rca input) One thing i can tell for sure: without usb power supply device doesn't work at all.

No, VGA has to be the source. You can use our HDMI to VGA adapter: http://www.amazon.com/Cable-Matters-Gold-Plated-Adapter-USB-Power/dp/B00879DM56/ Please make sure your laptop has a HDMI port.

No. USB adapters only transfer data (files like documents, pictures, etc.). This product will not project your computer screen, no matter the age of the TV. In fact, I have no idea why a product like this was ever made. Do not purchase it.

I would check that all connections are not loose. It sounds like you have the power usb cable plugged in but check it's connection as well. I'd suggest contacting the company if you have further problems. My monitor has worked flawless since installing the adapter. Sorry to hear you are having issues.
