Tech Tips – Ways to Improve Your Ability to Discern Low‐Contrast Differences

The next few blog entries will focus on ways to improve your ability to discern low‐contrast differences (subtle differences in gray-shades).

These tech tips come directly from one of our diagnostic display experts, Ana Greco. She has been with Richardson for 15 years. We don’t just give anyone the “expert” title. We consider Ana an expert because of her years of education, training, and hands-on experience working in different OR/PACs/Radiology reading room environments across the country.   She is a master at troubleshooting and continues to receive rave reviews from our customers. Three cheers for Ana! Thank you Ana!

Tech Tips – Ways to improve your ability to discern low‐contrast differences:

1‐ Clean your display

Fingerprints, especially on touch‐screen displays like iPad tablets, will reduce your performance. Similarly, dirt and dust on all displays will reduce performance. Be careful when choosing to use protective panels as dust behind them sometimes cannot be cleaned.

2‐ Reduce ambient light

Anything to reduce ambient light will likely be helpful. Work from an office (vs public work area with bright lights), close the curtain, turn down lights, turn off lights…

There will be more to come in the next few weeks, but if you need to talk to one of our display experts (including Ana) , please contact us at: healthcare@rell.com or 888.735.7373

 

Tech Tip: Driver Uniformity

At Richardson, we pride ourselves on having a pretty awesome technical support team. If you don’t know that already, you should give them a call sometime.

It’s always fun to reach out to our tech team for blog topics, and learning, “What are our customers calling about?” Here is what our tech support team member, Steve Borchard had to share:

 

I like to talk about driver uniformity.

If there are two different video cards in a PC, it is important to ensure that the driver is uniform between the two cards. It is important that these cards be in the same family of graphics card so that they can unify the driver (use the same driver).

If, for example, you were using an ATI card with an Nvidia card, this could be the worst case scenario. Although you may receive video on your monitors, there are a number of things such as communication protocols that common users may or may not notice that will affect the stability of the system and may affect video processing times or include glitches, tearing or general instability.

This is one of the more complex issues I have helped resolve when noticed. Some people may not know that GEForce drivers do not unify with Quadro cards even though they have the same Nvidia manufacturer. Again you may have video, and the common user may not notice any related issues or may not identify the root cause as being conflicting drivers. Some of the symptoms you see with this issue include display calibration errors, general video stability and processing speeds.

It is not always known that once an ATI card is installed there are entries into the registry that are not removed with automated software removal procedures. There are times when even after the hardware and software are uninstalled, a base disc image is created and an ATI driver remnant will get passed to imaged clients. The most successful, complete removal requires edits to the system registry, which if not completed properly cause additional glitches to occur. Generally speaking, ATI drivers appear quite sticky and difficult to remove in an automated fashion.

I have referred to the following forum on the internet for the best way to remove ATI remnants. This instruction has been a confirmed fix to just about every inquiry we’ve gotten on this topic.
