View Full Version : G74SX Video problem only on initial bootup

I replaced the 1600 X 900 screen on my G74SX-BBK7 (Bust Buy version) with a 1920 X 1080 that I ordered online and had shipped out here to Afghan.

When I initially turn the machine on, the ASUS screen shows and the "Starting Windows" screen with the logo appears, the screen then goes dark. Not completely black, can still see the faint glow indicating that it's powered up, just nothing visible. If I press the power button and put the computer to sleep (After the HD access light stops flashing indicating that it's booted up) and then wake it back up with the power button, the screen comes up but only portions of it, until I move the mouse..........then my log on screen comes up clean and everything works fine.

I've never seen anything like this.........current video driver (which worked flawlessly with the 1600 X 900 screen) is 8.17.12.8562.

Anyone?????

Did you uninstall and reinstall that nvidia driver? 285.62 (as we call it, here) :D

Also, maybe there's a profile or driver for that display. Google the display id and see what pops up.

Thanks for the answer. No I didn't and haven't tried a driver reinstall, it takes about 3 hours to download the thing out here and I am not sure I saved the file from the last time.

I did do an automatic search for any updated "monitor" drivers through device manager and it came back as up to date, still listed as a generic PnP though, not sure if that matters or not. I already trashed the box the new display came in so I'll have to pull it apart again and see if I can find a model number or something. Thanks again.

Re do the chipset drivers from the command line with -overall as a switch, first.

You can get the model number from Device Manager. Right-click on the "Generic PnP Monitor" and choose "Properties" from the pop-up menu. Select the "Details" tab and click on the down-drop triangle on the right side of "Device description" in the Property section and select "Hardware Ids". The model# will display in the "Value" section.

On my G74SX-AI, it displays MONITOR\CMO1726 (a monitor produced by Chi Mei Electionics in Taiwan). This monitor uses the Microsoft PnP driver version 6.1.6700.16385. Chi Mei does not supply a driver for this device.

I am running the stock NVIDIA 8.17.2.6837 video driver.

When I right click and select properties and details it just says Generic PnP Monitor and the drop down box that says Device Description has no options in it.

I took it apart again and got the model number, it's an LG Phillips LP173WF1 however I am not having any luck at all finding information on drivers for it specifically. I suppose there are worse things than having to put it to sleep in order to use it but it's annoying to say the least. I also loaded and tried Bad Company 2 and it was jerky and not really playable whereas before it ran smooth on advanced settings. I tried MW3 on it and it screamed through it though so I'm at a loss.

Try what I told you and if that doesn't work get back to us.

No change, in fact I had to put it to sleep and wake it up to get the screen to come back up when it blasted the video chipset. Once I brought it back up it said I needed a restart, did the restart, same situation. Screen passes the Windows is Starting screen and goes blank. Looks like a normal LCD that is turned on but has no signal going to it. Going to try to reinstall the video driver and see if that makes a difference.

I looked up the detailed properties on the monitor again after the chipset deal and it still shows as Generic PnP with no other option available.

Download the Ubuntu ISO I posted in the New Drivers thread and burn it to a CD. Boot from it and see how your display reacts. If it's fine, I'd say it'a a windows problem we haven't figured out yet, otherwise it's just hardware related and you need to solve that. Make sense?

Yeah that makes sense. Connection is so lousy out here that I'll probably end up waiting until I get home on leave next month though. I'll just live with it the way it is for now, or I'll put the old screen back in it.

Thanks for the help.

If the Property drop-down box in the "Details" tab has only "Device description' in it, it sounds like a hardware recognition problem. I'm thinking (but not sure) that the BIOS needs to recognize the LCD screen, since mine (the Chi Mei 1726 which also displays as a "Generic PnP Monitor") IS recognized with the Microsoft driver (i.e. not a driver issue).

Did you reset your BIOS after installing the LP173WF1 display (see http://www.ehow.com/how_6827437_reset-bios-asus-laptop.html)?

Did the new display come with its own cable? I remember reading somewhere that the 40 pin LCD video cables are NOT standardized.

Did the retailer of your LG Phillips LP173WF1 indicate it was "100% compatible with your G74SX-BBK7"?

Stay safe out there, SlimShady!

The BIOS reset... Good idea Drew!

No I didn't reset the BIOS, will try that now. The new display did come with a cable and based soley on color coding, it's a match for the cable that was on the old display as well.

I did a search for the LCD based on model of computer and it came up with the 1600 X 900 as well as the 1920 X 1080 that I purchased, that's as close as I got to being told it's 100% compatible however. If it doesn't work I still have the old screen, can put it back in, sell this laptop and pick up an A1 or better next month when I get home.

Thanks again for the help.

Okay, did the BIOS reset (not exactly like the description in the link you gave me but I managed it I think) and no change..........one other thing I've noticed is that when I put it to sleep and wake it, when it starts back up the entire screen is momentarily black with the exception of the white box where I enter my password for logging on........and that is shown in two locations....then it flashes and the standard blue screen with the logon box comes up and it seems to work fine. I'm going to see if I can find an updated BIOS for the laptop and try that, if that doesn't work then old screen and for sale.

Thanks!

The updated BIOS is 203. There's a link in my sig. And instructions at the end of my New Drivers sticky.

BTW, when in the bios all you need to do is press f9 to set the optimized defaults. (Reset) :)

Yeah I figured that BIOS part out, thanks.

I have reinstalled the original screen, problem solved......so it's either an issue with the hardware (screen itself) or as you guys have said, software related. Maybe a new BIOS would help but at this point I'm tired of messing with it. As long as it works I'll keep it until next month. It's a good computer, runs great, very few complaints (occasionaly kicks me out of games) but I wanted the true HD.
