| 70 of 73 people found the following review helpful  Ideal for stock traders, By Gary Keene "Eclectic Reader" (Carlsbad, CA) - See all my reviews Amazon Verified Purchase(What's this?) This review is from: Diamond BVU195 HD USB 2.0 to VGA / DVI / HDMI Adapter (DisplayLink DL-195 Chipset) (Personal Computers) ADDENDUM, 8 months after initial purchase. Not sure I can recommend this as highly as before. I still use two of these on a daily basis, to create the 3-screen display described below. But I've noticed that the screens will sometimes give a big blink, go black for a few seconds and when they recover, several things will go haywire: Resolution becomes wrong, portrait/landscape setting is wrong, and the desktop icons will resort themeselves into nonsensical locations. Usually I can just restart the computer and everything will recover, but not always. I think it's a hardware/software conflict - I believe the Nvidia video controller built into my motherboard is trying to get control of the USB displays, and this seems to mess things up. You may not have the same issue. The restart-fixable fault occurs about every 8 days, whereas the major fault where everything gets fouled up occurs about every 2 months. And one other fault - sometimes one of the screens will suddenly be gin to display a series of primary colors, blinking red-green-blue forever until I turn that monitor off and on again. By the way, I do have the latest video drivers loaded for all devices.ORIGINAL REVIEW: A little background and history: My stock trading multi-monitor setup has 3 monitors: the center 24" widescreen monitor is 1920x1200, and the secondary monitors on either side are 19" widescreens (1440x900). One of the side monitors is rotated +90 degrees and the other rotated -90 degrees to portrait mode. My desktop PC had a built-in video driver. In my first attempt to build a triple monitor system, I naively installed a dual output ATI video card, thinking I could use those two outputs in conjunction with my existing internal video to acheive a triple monitor output. I was disappointed to discover that the ATI card disabled the internal video card, so I was left with a dual monitor system. I lived with that for a while, but found that the ATI card freque ntly "forgot" which monitor was the primary monitor, "forgot" that one monitor was rotated to portrait mode, and even "forgot" that there were two monitors. I would turn on the PC to discover that the primary monitor display was rotated 90 degrees and the secondary monitor had no display, so I would have to tilt my head sideways while I tried to reset all the parameters to my preferred settings. The saved settings file seemed very unreliable. Still wanting 3 displays, I finally ponied up almost 0 for a Matrox quad monitor display card. What a disaster. The available resolution settings did not accomodate widescreens, and certainly did not accomodate having one or more screens rotated. Each pair of the four outputs had to be the same resolution, and you could not control placement of the primary screen between the secondary screens, in terms of the mouse movement. As I continued to research multi-monitor displays, I finally discovered USB multimonit or display adaptors. I purchased the Diamond BVU195 rather than some less expensive alternatives for several reasons: It supported a higher resolution than many other products, and it offered Vista compatibility. (The cheaper Diamond BVU160 is identical in every specification except is not certified for Vista and Windows 7. I do wonder if this is an artificial price difference. If anybody has successfully installed the BVU160 on a Vista system, I'd like to hear about it. The BVU195 Vista driver is available as a free download from the Diamond website, and I have a suspicion that you may be able to purchase the cheaper BVU160 hardware and download the BVU195 Vista driver for it. However, I HAVE NOT TESTED THIS, so it's buyer beware if you attempt this.) Anyway, I bought two of the BVU195 and installed them in my desktop, to drive the smaller secondary displays that sit right and left of my primary display. My primary display is driven by the video built into m y desktop, while the secondary displays are driven by the two BVU195 plugged into two USB ports. Installation and setup was far easier and faster than with the earlier ATI and Matrox experiments. The BVU195 coexists perfectly with the pre-existing on-board video driver. I was very pleased to discover that I can independantly and easily control the resolution, rotation, and placement of each secondary monitor in relation to the primary monitor. If I want, I can place the secondary monitors above or below the primary monitor, or both on one side, and the mouse arrow will flow from one screen to the next in the expected fashion. I was so pleased by the experience that I gave a presentation on this setup to my local stock trading Meetup group. I was able to easily demonstrate setting up the multi-monitor display on a PC desktop, a PC laptop, and a Macintosh laptop. At one point of the presentation, I was driving a 46" LCD TV at 1900x1080p, a 24" monitor at 1920x12 00, and a 19" monitor in portrait mode at...

This review is from: Diamond BVU195 HD USB 2.0 to VGA / DVI / HDMI Adapter (DisplayLink DL-195 Chipset) (Personal Computers) Before buying this product I read all of the reviews. Nervous about getting this device for my Mac Mini I dove in and ordered it. It came in a timely manner. It is small. Great. It is easy to set up, just plug it in. Great. But when I turned my monitor on. Nothing. Yikes.... Another Mac person who bought this product warned that there were not any MAC drivers on the CD that came with the device, or on the Diamond website. Check. He is right. That is still true as of this review (9-30-10). But being like a pit bull with the Internet, I knew I could probably figure it out which is why I ordered it anyway. I figured I would give it a try being somewhat optimistic in general.The other reviewer was definitely correct. BUT..... here is the great news! when I opened the device I noticed that printed directly on the device was the company name "Display Link." Aha! They might have the drivers. Sure enough. The drivers were there on their website. Here is the url for the MAC drivers. [...] I downloaded it and voila! My monitor came on. I was thrilled. So alas, like many new devices these days the hardware company makes one thing, and the software is developed by another company. So wonderful Mac User, don't despair. The product is there. Its a great little product. Without the USB adapter there would be no way I could run two screens on my mac mini. My mini is about 3 years old so it only has one port for a monitor. I use the screens for Pro Tools and recording music in my home studio and the device is working great!!! Good luck! 34 of 39 people found the following review helpful  DO NOT BUY if you have a new Mac Book Pro. (But see the Edit), By Amazon Verified Purchase(What's this?) This review is from: Diamond BVU195 HD USB 2.0 to VGA / DVI / HDMI Adapter (DisplayLink DL-195 Chipset) (Personal Computers) EDIT 2/1/11:The fix, suggested to me by the manufacturer, consists of turning off automatic graphics switching on the newer MBP models. This option is found under SYSTEM PREFERENCES > ENERGY SAVER > AUTOMATIC GRAPHICS SWITCHING. Uncheck the box (at the top left of the window) to turn this feature off. You will consume more battery power, but the computer will be stable using this USB video adapter. I haven't tried running the beta driver from Diamond, etc... This solution works, but I don't like the lack of support from Diamond. Best of luck. ORIGINAL ENTRY: I just spent my entire weekend trying to fix a disaster caused by the Diamond BVU195 and/or the DisplayLink software. I had been running one 24" Dell external monitor at my desk from the mini-display port, but I wanted a second external monitor. I went ahead and purchased everything I needed -- a dual arm mount and another 24" Dell, along with the Diamond BVU195. I should mentio n that I'm running all this on a very new, mid-2010 model MacBook Pro with 10.6.4 and the recent (8/20/2010) graphics update. After installing everything ran smoothly on the dual external monitors. It was very nice to have the additional screen space to work with. Leaving that evening, I put my computer to sleep, disconnected the cables, packed it up, and went home. The next morning, I was using my MBP at home without any external monitors. Everything seemed to be working fine for a number of hours. However, while quitting out of a program, the screen went black, and then became stuck on a snow pattern (after restart, it was locked on a light blue screen similar to the screen seen during start-up). I cursed, fiddled, called apple care, and essentially did everything I could think. In the end, I made an appointment at the Genius Bar for help. I worked with a pretty smart guy for the better part of an hour. We discovered that, on restart, when the screen locks blue, doing a "blind logoout" ("Control-Shift-Q," then "Return" -- blind because you can't see what you're doing) will bring you to the login screen. Everything worked after this except the screen would lock blue on start-up. So, in order to make my MBP work properly, all I had to do was start up, wait for the screen to lock blue, Control-Shift-Q, hit return, and re-log in. For some reason, this bypassed whatever was causing the screen to lock up. The genius bar guy's suggestion was that I restore my system from a time machine back-up. So, I spent my entire evening and all of last night driving to my office, getting the system restore discs and my time machine drive, and restoring from a time machine backup. I selected the most recent time machine backup prior to the crash -- as suggested by the genius bar buy. Because everything had worked fine between installation of the DisplayLink driver and the graphics crash, neither of us thought (naive in hindsight) that the DisplayLink software could have had anything to do with it... On restart after the restore had finished, I was still having the same problem. After reading a recent comment to an article on the-gadgeteer titled "Diamond USB Display Adapter Pro Review" (this: [...]), I immediately uninstalled the DisplayLink software. It looks like that solved the problem. Apparently, there is a fatal conflict between the new graphics-switching routine on the new Core i5 and i7 MacBook Pros and the DisplayLink driver software, resulting in a very frustrating graphics crash. Diamond/DisplayLink seem to acknowledge an issue ([...]), but their sole fix is to suggest you disable automatic graphics switching, which isn't really a solution. I absolutely would not recommend this product. |
