grain Posted October 4, 2015 Posted October 4, 2015 Any ideas why Autocad LT 2009 should dip its brightness everytime I go into model space. This has just started happening without any logical reason. (I had changed the colour display from white to black background) Quote
ReMark Posted October 4, 2015 Posted October 4, 2015 Maybe it's somehow related to your graphics card? Is this computer as old as the software that you are using? Quote
grain Posted October 4, 2015 Author Posted October 4, 2015 Hi ReMark The computer has an i7 processor with a Geforce GT220 graphics card. Quote
ReMark Posted October 4, 2015 Posted October 4, 2015 Are you seeing anything unusual when you use other programs? Quote
grain Posted October 4, 2015 Author Posted October 4, 2015 No ReMark there is no dimming of brightness happening on any other program and it only happens if I try to change the colour background in 'Options' to black from the usual white that I use. Quote
ReMark Posted October 4, 2015 Posted October 4, 2015 Are you selecting the word "black" or specifying a red-green-blue number sequence? Quote
RobDraw Posted October 5, 2015 Posted October 5, 2015 It could also be one of those "fancy" auto-adjust settings on the monitor. Quote
RobDraw Posted October 5, 2015 Posted October 5, 2015 Can you post screen shots of this dimming (before and after)? Quote
grain Posted October 25, 2015 Author Posted October 25, 2015 Hi Rob I think you are right it looks like an auto dimming issue with my Samsung monitor. It only happens with black. If I choose a dark colour from the options display there is no dimming of the screen. When I choose black even the print screen I took had the dimming effect kick in after a half second. Thanks you for your comment. I will stick with a dark colour display until I get a chance to look into the monitors controls. Quote
grain Posted October 25, 2015 Author Posted October 25, 2015 Yes it was the 'Dynamic Contrast' in the Monitor controls Quote
grain Posted November 7, 2015 Author Posted November 7, 2015 Yes Rob it was 'Dynamic Contrast' Option on my monitor. Thanks. Quote
Lorelei Posted August 24, 2020 Posted August 24, 2020 I solved it by changing the screen setup. (it had nothing to do with ACAD) Picture / MagicBright / Dynamic Contrast Picture / MagicBright / Custom or Standard Quote
