In our previous post “The Desktop PC – Still Relevant?”, we touched on how the industry is trending more mobile, and the sizes of the devices we use are changing. Laptops are cheaper than they’ve ever been. They are thinner and lighter than ever, and they are much more powerful than they were even a few years ago. With that being said, we’d like to delve into a few minor setbacks to the cheaper, thinner, lighter laptops of today.
Computer technology seems to change over night at times. One aspect of that technology that confuses many people are the video connection standards. There’s a few of them and they are constantly evolving. In this post we hope to clear up a little of that confusion.
Let’s go back to the beginning of consumer computing, and explore how it’s evolved from there.
CGA (Color Graphics Adapter) – First available on the IBM PC in 1981 as IBMs first color display card, thus the first color display standard. It only used 16 kilobytes of memory and displayed at 640×200 @ 60mHz 4-bit or 16 colors. It connected using a DE-9 (9-pin) connector.
EGA (Enhanced Graphics Adapter) – The next leap in display standard evolution. Introduced in 1984 by IBM, it displayed at 640×350 @ 60mHz & 16 colors. This graphics card had 64KB of onboard ram. It also connected using a DE-9 connector.
VGA (Video Graphics Array) – This is the video connector that most computer users are familiar with. Introduced in 1987 by IBM with the debut of their x86 computers. Connected with a DE-15 (15-pin) connector, VGA was the last of the analog video standards to be developed. It displayed up to 2048×1536 @ 85mHz and 256 colors.
Here and Now
DVI (Digital Visual Interface) – Developed by Digital Display Working Group in 1999, this standard could be configured be configured to support multiple modes such as DVI-A (analog only), DVI-D (digital only) or DVI-I (digital and analog). Featuring support for analog connections, the DVI specification is compatible with the VGA interface. DVI has a unique horizontal connector that .varies slightly depending on the configuration. It can display 2560×1600 @ 60mHz or up to 3840×2400 @ 33mHz.
HDMI (High-Definition Multimedia Interface) – HDMI is currently gaining traction as the de facto video connection on desktops, notebooks, and even mobile devices. HDMI is a digital replacement for analog video standards. It can transport compressed, uncompressed, video and audio, and auxiliary data. Different versions of HDMI have been deployed since the initial release but all use the same cable and connector. Other than improved audio and video capacity, performance, resolution, newer versions have optional advanced features such as 3D, and Ethernet data connection. Displaying 2560×1600 @ 75mHz or 4096×2160 @ 60mHz, HDMI uses a much smaller connector than DVI.
DisplayPort – A digital display interface (designed by VESA – Video Electronics Standards Association) primarily used to connect a video source to a device such as a computer monitor, though it can also be used to carry audio, USB, and data. DisplayPort was created to replace VGA & DVI, and is backward compatible with VGA, DVI and HDMI using the appropriate adapters. It can display 2560×1600 @ 75mHz or up to 8192×4320 @ 60mHz. DisplayPort uses a 20pin connector.
Mini DisplayPort (Thunderbolt)
If you’re using an Apple computer, new systems come with Mini DisplayPort. Mini DisplayPort is the same connector as Intel Thunderbolt technology allowing that port on new Macs to do more than just video. It’s used in Apple Cinema displays and has adapters for DVI, VGA, HDMI or regular DisplayPort. Mini DisplayPort uses a small 20-pin connector seen on Apple devices and some PCs and PC graphics cards.
Today’s computers, both laptops and desktops typically are coming with HDMI or DisplayPort as video connection options. You can still find DVI and VGA on some models but it is quickly being phased out by the new, more powerful digital standards. Flat screen TV technology has also embraced these digital standards for connecting not only your computer but other devices to your TV.
We hope that this information has made understanding the video connection varieties a bit easier. If you have further questions about this topic or any other, feel free to email us, call us, or contact us through the website.

Q & A: How Do I Setup Automatic Backups On My Macbook/Macbook Pro?
Welcome to another segment of Geek Easy Computers series on expanded answers to common questions. A question we get asked quite often by Mac users is how to setup automatic backups on their computers, so we put together this short instructional guide!
Apple computers (Macbooks, Macbook Pros, iMacs) have always had the reputation of being “virus proof”. And for the most part, that reputation was true. But not for the reasons most people think. It wasn’t that viruses couldn’t be written for the Mac OS (operating system), it’s just that the Windows OS user base was so much larger that the criminals creating computer viruses thought it not worth the effort to target the relatively small Mac percentage. Therefore, for the longest time, Mac users enjoyed a sort of immunity from the attacks and having to safeguard their data from viruses.
This past year has been an exciting one in many respects. It has definitely been a roller coaster of a ride. The ups and downs of the economy, the re-election of the first African-American president, the ongoing conflict in the Middle East. So many newsworthy events took place it’s nearly impossible to comment on them all.
It’s 2013! Happy New Year! Where did 2012 go and doesn’t it seem like we were just celebrating the beginning of 2012? Well you know the old saying “Time flies when you’re having fun!”. 2012 has been a wild ride for us here at Geek Easy Computers, but overall it’s been a fun and exciting trip!
Have a MacBook purchased between Oct 2009 and April 2011? Well if you have any issues with the bottom of the case, specifically where the rubber on the bottom of the case separates from the bottom cover, Apple will replace the bottom cover FREE of charge! You will, of course, need to provide your serial number. You can make arrangements with your local Apple Store Genius or your authorized Apple Repair Center.
You can also have the part shipped directly to you, if you are comfortable doing the install yourself. Alternatively you can order the part and have Geek Easy do the install for you! The repair kit, which includes the new case bottom, screws, phillips screw driver, and instructions, can be ordered below:

Mac Defender and variants of the latest Mac malware
Normally news of major Internet virus threats is exclusive to Windows, but not anymore. Word of the Mac Defender variants has spread faster than the malware itself, and it’s sparking bits of controversy on the web. From debates about the security of Mac OS as a whole, the need for antivirus software on Macs, and Apple’s response to Mac Defender, there’s probably been more written on the subject in the past few weeks than anyone would care to read.
But given that Apple computers are probably the most common manufacturer of PCs we repair, we thought it might be nice to summarize what’s being said on the subject.
