Hello Mr Intel I need some someone with HEX translatoin skills to assis in the modification of my igdih.inf data file. I was wondering if one of you kind folke will be able to spare 5 mins to assist in my overscan issue? No realy I only need 5 mins. I'm the owner of a Shuttle SG33G5m HTPC running an Intel G33 chipset and want to have native resolution on my TV with no overscan via HDMI. Below are my LCD TV monitors VGA specifications according to my TV's manual.
The manual also states that DVI does not support PC function and the manufacturer stated that I must use VGA. I dont want to do this though, I just want to be a pain. Samsung 40 Inch LA40R71BDX 1360 X 768 Resolution (VESA) 47.712 (kHz) Horizontal Frequency 60.015 (Hz) Verticle Frequency 85.800 (MHz) Pixel Clock Frequency Sync Polarity (H/V) + / + Running MonInfo I get the below. I can see in the Raw EDID base information that my TV's native resolution does not appear thus I am not able to copy the information out and place it in the igdih.inf file.
I would hook up a VGA cable and run MonInfo again to get the information although I cant get VGA out on my PC. I have attempted to do so (spent 10 minutes on it) although I have had no luck. What do I want here and now? Someone to edit my monitor info from the Raw EDID base data so that I may use 1360 X 768 resolution.

1280x720 at 50Hz Modeline. TVWizard gets re-released with every new driver release, so I'd expect one in the next couple weeks or so. Not sure you're going to get what you want out of that, anyway.
Your monitor is telling the world through EDID that it wants 1280x720, which is no doubt why your manual claims you'll have to use VGA. Some monitors are like that- their DVI or HDMI input is configured to only accept some non-native resolution, while VGA works fine. Either go with VGA to get native rez or try to adjust for overscan using some other tool (TVWizard, if it's working; Powerstrip + DTD registry hack, etc.). Here's the DTD you want if you want to try it anyway, but I doubt it will work except over VGA. The digital input chip on your monitor is limited to 'standard' resolutions, despite what your monitor can actually handle. 66 21 50B0 51 001B 30 40 70 36 00 00 00 00 00 00 1E 37 01.
Big thanks for the HEX translation! Going to see if I can get VGA up and running on my TV then and mod the.inf file. If this works then all I need to do is figure out how to get sound from my motherboard out to my TV. Another issue for another forum.
Base on the outcome of the above is, anyone interested in purchasing a gold plated 3 meter HDMI cable? I need to rant now so if youre interested please read on. Me and a work colleague are PC enthusiasts and have both recently stepped into the HTPC arena. We both wanted a solution where a built in GPU would be able to meet our display requirements.
Intel seemed to have the hardware we require nailed down, in my case through the Shuttle SG33G5M (Intel G33 chipset) and my college through the ASUS P5E-VM motherboard (Intel G35 chipset). Both PC hardware solutions offer HDMI out built in, fortunately for my colleague he runs a 50' Sony Bravia with 1:1 mapping, the Sony LCD hardware corrects any overscan issue. My LCD hardware (Samsung 40') is a little older and does not have the same capabilities.
I called Samsung to fish for more information (Firmware upgrade?) and it was made perfectly clear that all past and present Samsung LCD models will only support PC connections via VGA not HDMI. I'm not sure who is responsible for correcting overscan and native res display issues, TV manufactures for not offering a better hardware based solution or PC hardware manufactures for not offering a better hardware based solution. More and more people will be purchasing Intel HDMI based PC hardware to hook up to their LCD TV's and if the LCD TV is not capable of correcting overscan and native res issues then individuals will be looking for a solution from the PC hardware manufactures, in my case Intel. This is a great forum and well done to Intel for allowing people to complain about their products on their own web site. I just hope that the appropriate people from Intel are listening closely to what is going on here as is not going to go away any time soon. Building in HDMI into motherboards is an awesome step forward especially if you want a non gaming HTPC solution. It's a shame this hardware advancement comes with an ugly side.
Excellent rant, and I agree 100%. I think Intel's working on the issue, and the indications I've seen are that there will be hooks into the drivers to perform custom resolutions a little easier in mid-2008.
However, as with the TVWizard, support may be limited to certain chipsets.:( That part I don't know. However, a group of coders in Britain have a tool in beta which makes the situation a little better/easier- I supplied the equations and they did the hard work. When it's public I'll post it here.
Overall, the Intel G33 Express Chipset has poor performance. This is not altogether surprising, as it is an integrated GPU. If a robust graphical system is desired, a dedicated graphics card upgrade is a must, though you can get away with an integrated GPU for less intensive applications and games. This integrated GPU is now over 11 years old, which means it is extremely out of date and is based on very aged technologies. This integrated GPU will be dwarfed in performance by its modern counterparts, and will likely have very little driver support from Intel.
The GPU is not too power-hungry at 19 Watts.
