VGA vs. DVI/HDMI

Image
By

There have been countless pieces written on this topic but frankly I never read them until I got a new 24” monitor that had a HDMI input. I was not happy with the HDMI from my PC to my 40” so I hadn’t planned on bothering with the HDMI to DVI on my 24” monitor until I saw an Amazon HDMI to DVI cable at a reasonable price ($7.49). What the heck, I bought it and tried it out.

I saw no difference between VGA and the DVI/HDMI. I found this curious so I googled VGA vs. DVI/HDMI and most of the posts I found were several years old. I did find one post that was more recent and made sense. The bottom line as I could see was that unless you have specific video needs there isn’t a whole hill of beans difference. VGA is analog and DVI/HDMI is digital so theoretically digital should be better. However the majority of users are not involved in situations that stress either choice.

BTW there are several HDMI connectors so once again a picture is worth a thousand words. I own 5 HDMI cables and of course none of them were HDMI to DVI. The picture at Amazon made the cable selection very easy.

So if you have VGA and are happy with the visual aspect you probably don’t need to upgrade. If you are running some serious video components and want to receive your audio signal digitally (DVI/HDMI carry audio and video digitally) then DVI/HDMI is a better choice.

Samsung FlipShot-ho hum

By
I just got the Samsung FlipShot aka SCH-U900. If you haven’t noticed by now, I am very family oriented, specifically focused on grandchildren. I frequently lament that I don’t have my camera on me. However, I always have my phone on me. Thusly I wanted a phone with a decent camera. The FlipShot comes close. Samsung claims it is a 3 megapixel camera with flash and zoom. The photos are not what I would consider decent from a digital camera but compared to my last phone/camera, they are much better. The phone has a slot for a micro sd memory card. I popped a 2gb card in there for saving my photos. I have not been able to find a way to default the photos to the memory card. You have to manually move them. I haven’t given up and perhaps in a software upgrade there will be a way to get them to the card without moving them manually. Getting them off of the phone is interesting. If you don’t buy Samsung’s charging/data cable, you can send them to yourself and get them on your pc that way. You ...

3D Printing—Way, Way Cool

By
You may not be familiar with the term 3D printing but I bet you remember the replicator from Star Trek. Well kiddies, it is no longer just science fiction. Replication exists! Analog Science Fiction and Fact had a great article in the November 2008 edition called: “The 3D Train Wreck”. Thomas A. Easton, the author gave a great overview of the future of 3D printing. Simplistically, take your 3 dimensional CAD drawing and print it out on a laser printer that will print layers with some type of raw material. Each layer is adhered to the previous layer until you have a full three dimensional finished product. There are a variety of existing technologies that are doing this right now. Rapid-prototyping in industry is the biggest market right at the moment. Consider how incredibly convenient it would be to fabricate or replicate things right at home. My Polaris pool sweep needed a part yesterday. The part is unavailable, without the part the sweep doesn’t work. The alternative was to buy a...

Troy-Bilt 2700 PSI 2.3 GPM Gas Pressure Washer Review

By
Troy-Bilt 2700 PSI 2.3 GPM Gas Pressure Washer Review Item #: 75140 | Model #: 20414 When I started this blog, I assumed I would be only talking tech. Well that led to philosophic musing and then comments on other stuff. I’m not sure where a pressure washer fits but regardless I am writing about it. I was power washing the mildew off the siding and thought the odor was the detergent I was using. When I looked over my shoulder and saw the grey smoke pouring out of the pressure washer, I realized what the odor really was. Considering the age of my venerable electric power washer, I concluded that discretion being the better part of safety and how water and electricity don’t play well, I trashed my old power washer. After much research, I found the Troy-Bilt 20414 was the best bang for the buck I could find. Keep in mind I am a consumer, not some testing house, so I make my purchases based on research and price point. I wanted electric but my boys who participated in the purchase, ...
