Is this thread dead already? Still looking for help please. I'm on my 6th video card and still not working. I will try anything that anyone can suggest

can anyone help?

Just picked up an EVGA GT 640 to try out. if anyone has any experience with that card, let me know so I can get this build finished. thanks.

This is my exact GPU card: http://xfxforce.com/en-gb/Products/Graphics-Cards/AMD/ATI-Radeon-HD-5000/ATI-Radeon-HD-5450.aspx

I still would like to know how I can get the integrated graphics working.....I just get Kernel Panic booting with the DVI/HDMI on motherboard.

Here are the two matching screens I'm using. http://www.upstarusa.com/TV-LCD-25.html Is there anything you can tell me from knowing the specs?

They are cheap screens and only have aspect ratio adjustments to include zoom. The zoom goes way too far in and crops anyway. I'm thinking the EDID from the screens or something is not recognized properly? Is RADEON the only manufacturer that has the Underscan slider show up in hackintosh builds? Please let me know what to do, should i get another card from the store that will work for me? The HD5450 has the slider but the acceleration doesn't work in OS X (QE/CI i guess) doesn't work. Looks great but is slow and lame. There are people @ osx86.net claiming the HD 5450 works completely but I think they are mistaken. http://www.osx86.net/view/3043-ati_radeon_hd5450_with_full_qe-ci_support.html You can see my frustration at the end. I bought the stupid card because everyone said it worked but I need dual screen with full acceleration. I think people just say it shows up on the screen and that's good enough. Anyway please give feedback. Also, I'm not getting e-mails when you respond to this thread not sure why......

Any help?

Do you think you can help get my HD4000 going without Kernel Panic? I haven't even been able to see what that does to the image yet. Should I get another GPU card to try? I also have another GPU card I can try but have to take it out of an existing build, it's the card in my HTPC. The card is an ATI RADEON HD 5700 series. Tell me if you think it is worth trying out because it will take a lot of work to un-rack it.

Well, the display doesn't give me option for over/under scan adjustment. If I tick the Overscan box the image is cropped off and doesn't fit the screen. If I leave it unticked, I get a black border around the whole desktop display. That's really the only thing I care about. The only GPU that gave me perfect sizing without adjustment was the PNY 8600 GT. The only card that gives me the option to resize is the ATI Radeon HD5450.

This is the first DarwinDump of Extra after the first few attempted fixes and install of nvidia installer. I performed the latest multifail package install and Profiler shows no difference. The graphics still reported as Unknown 1024MB MSI H55M-E33 with GT 620 Extra V1.zip

I installed the Extra folder you sent me but I don't see any difference. The display is still cutoff. It doesn't look like the card is even recognized still. Both DVI ports are working for both displays just cropped off. OpenGL Extensions Viewer 4.0 ---> nvidia GeForce GT 620 OpenGl Engine is displayed. I go to about this mac, under Graphics I see Unknown 1024 MB.------------------------------------------------------------------------------------------------------------------------------------------------------------------------- I installed 304.00.05f02 from nvidia and installation was successful. Ran myFix full. Restarted Same findings. Unknown 1024 MB in About this mac. OpenGL Extension Viewer shows the nvidia card. Video still cropped, I untick the Overscan tickbox for both displays and the image comes back with black border around the images. No slider for Under/Overscan adjustment to fit to screen.

Here is my extra folder with the EVGA GT 620 1GB connected to two DVI displays. MSI H55M-E33 with GT 620 ORIGINAL Extra.zip

Installed succesfully using MyHack with dmg of 10.8.2 ML with latest MyHack. That nvidia link you posted is still coming up not found on the nvidia site. Is this what you want me to get: http://www.nvidia.com/object/macosx-304.00.05f02-driver.html When installing this, it comes up with an error saying the system wont support the install? I have dual screen on both DVI ports of the EVGA GT 620 1GB in 10.8.2. Over/Underscan has tick box no scaling slider option and I have cut off image on both displays so I need to adjust. The display monitors have no way to adjust so needs to be done through the GPU card. The system sees that the displays are TV's which they are. the f4 key loads tiles quickly so acceleration must be working well. When I load OS X 10.8.2 with the ATI Radeon HD5450 1GB I only get one screen the loads while connected to DVI and HDMI on the Radeon card. The image is uncropped for the side that loads and in the settings I do have the Underscan slider for adjusting the fit to the displays. The f4 key load takes forever for the tiles to load. Acceleration obviously not there. Put an old PNY 8600 GT 256MB dual DVI ports and it actually loaded beautifully. I get both screens that boot the displays awesome and fit great without cropping! no underscan slider if needed ever but there is a Tick Box for Overscan. Suprisingly it looked like it had great acceleration when I hit the f4 key and those tiles load up quickly. No artifacts or slow movement. This is a great option and works well however it's only 256MB and I worry that it wont be enough for Video/Photo production work. This build is for Audio Production so perhaps it will be fine for the build at only 256 MB. I've tried booting without a graphics card and just using the two built in DVI/HDMI ports on the motherboard. I assume the graphics would then be HD3000 or HD4000 but I get kernel panic with all my SATA drives plugged in. I disconnect all NTFS SATA drives and leave only the OS X install connected I then get a kernel panic with AppleIntelCPUPowerManagement. Don't want to go further on this video option without any instruction. PNY 9600 GT 1GB This one boots to black screen after Macx_swap on success. Tried GraphicsEnabler=No/Yes and didn't matter, still boot to black screen. So there we are, five video options to choose from. Here is the DarwinDumper data for all video options: DarwinDumper_2.5.8_Chameleon_2.1_ML-EVGA GeForce GT 620.zip DarwinDumper_2.5.8_Chameleon_2.1_ML-ATI Radeon HD5450.zip DarwinDumper_2.5.8_Chameleon_2.1_ML-PNY GeForce 8600 GT 256.zip

the nvidia link is not working...I will reupload the DSDT....
