Kurt 0 Posted June 17, 2010 Al monitor manufactors changes their monitor lines to 16/9 or 16/10 aspect ratio types, as a replacement for the older 4/3 monitors. In fact 4/3 monitors with typical 1280x1024 or 1024x768 resolution start hard to get by these days. Most DVR's with VGA-output need a 4/3 monitor for optimal viewing. When a 16/9 TFT is connected to such a DVR all 4/3 video is shown in a 16/9 aspect ratio, and people look fat. Also with Geovision PC based software v8.2, I found that when selecting full screen viewing, it is the same problem. What solution are you guys using in such a situation? Just leave the 4/3 > 16/9 transformation like it is? Or trying to find 4/3 monitors? Then there a second factor responsible for some more quality reduction. Most TFT screens have a native resolution i.e. a 23" 16/9 model offering a 1920x1080 (fullHD) resolution. If the output of the DVR is only 1024x768, the monitor is working in a not optimal resolution. Even if a system can handle these modern hi-resolutions, how can it optimal display a matrix of 320x240 video channels? 6x320 = 1920 alright, but 4x240 is already 1200, to high for full HD (1920x1080). It looks like some black borders will be necessary.... or do we need widescreen camera's? Share this post Link to post Share on other sites
bongofury 0 Posted June 17, 2010 This is a good question. Myself have also wanted to know the answer. I still install the standard monitors, but I notice other LCD's put in by customers or competition are widescreen, and images look fat! Share this post Link to post Share on other sites
Soundy 1 Posted June 17, 2010 Personally, I install Vigil DVRs pretty much exclusively (many now replacing GeoVision systems), and they work just fine with the higher resolutions: I just set the Windows display resolution to match the monitor, and Vigil displays as normal - I just get a bit of blank space to the right of the camera grid. Their HD Viewer software that we use to show cameras on external displays allows me to custom-crop each camera to fit, as well, or just pillarboxes the display - as long as I can set the Windows screen resolution properly, everything displays perfectly normal.

koolmer 0 Posted November 13, 2010 Good DVRs have different camera setup for 16/9 screens. I use NetvisionDVR and if I choose a 16/9 resolution the setup looks like this: Of course there are more available setups, but this is just to give you an idea. Also good DVR Software should support 1920 x 1080, so that you don't loose quality because of interpolation. It is quite amazing how sharp a camera is displayed on such a DVR + 1080p screen, even when only a few centimeters big! There is much more resolution available for a VERY good and clear split view.

rory 0 Posted November 13, 2010 seeing as most CCTV cameras are under 800x600 pixels, anything over 800x600 is really overkill Share this post Link to post Share on other sites
koolmer 0 Posted November 13, 2010 seeing as most CCTV cameras are under 800x600 pixels, anything over 800x600 is really overkill Not if you use split screen Lets say you use a 1280 x 1024 screen for a quad display and the DVR supports the native resolution of 1280 x 1024. Then you have 640 x 512 pixel available for each camera. If you display 12 cameras on a 1080p screen then you would have still 480 x 360 pixel for each camera. This still gives you quite a good image. Share this post Link to post Share on other sites
