How do I get my LG LCD TV set to display Windows 7 in normal mode?

[Dusty Ayres]

My LG LCD TV set won't display Windows 7 in normal mode without flickering on and off, so I have to use it in Safe Mode. How do I get my TV set to do this? I've already spent $60.00 CDN to load Windows 7, and I thought that doing so would be different, but now I've seen that it was a waste of money, as it's doing the same thing that it did when I installed it myself. What do I do to resolve this; buy another monitor, or a new video card? Or do I give up on Windows 7 altogether? I'd never thought I'd say this, but: Somebody, please help me.

I have a 32" LG LCDTV (32LG40 I think is the model#) on W7 and it works fine, I don't remember ever having this issue. A few months ago I added an Onkyo 7.1 receiver to the mix and subsequently, I now have video signal going from my video card (ATI HD4850) in DVI to HDMI on the receiver and then HDMI out to the TV. Since adding the receiver I have had 1 or 2 instances in several hundred hours of operation in which the signal blacks out for a second or two but I have read that it's an intermittent issue with the Onkyo receivers on 1080p output (most commonly seen with PS3's).

What can you tell me about the cable you're using? Are you going native HDMI to HDMI or doing a DVI-to-HDMI thing like I am? It might actually be the cable you're using - I know you said it works in safe mode but that may be because safe mode is only trying to push a low resolution to the display. When I first hooked up a BD player to this TV I bought two HDMI cables - one was cheap (like $.90 on amazon) and one was like $10 on amazon. The cheap one blipped out and threw artifacts when I played blu rays in native 1080p - but played fine on 720. I suspect its cheap construction didn't allow for a clean 1080p signal, whether it was due to insufficient insulation quality or what I don't know, but the $10 one played 1080 or 720 just fine. It could be that your problem is similar - you have a cheap cable and in Normal mode W7 is trying to push a resolution (1650x1080 for instance) that the cable cannot transmit cleanly.

That would be the easiest solution to test - would be to go spend a little more money on an HDMI cable (or DVI to HDMI, w/e you're using), and see if it makes any difference. The only other possibility I can think of video drivers. For some reason your drivers don't like trying to push the max res that Normal Mode is trying to display. One way or another, I have a feeling that it's working in Safe Mode because it's not displaying in whatever high resolution or frame rate or something that it's attempting to use in normal mode.

Reply with video card specs, cable, driver version etc.

I would doubt that it's Win 7 causing the problem in and of itself. Sounds more like you have the video drive in windows set to high for the TV. Try reducing the resolution a bit. Check the TV's manual to see the max resolution it can do.

 

[John O.]

I suppose it could also be a 720p TV and you're trying to run it at 1080p (or windows is), I hadn't thought of that.

My video card is an EVGA card, the cable I've been trying to use is a VGA cable, and the drivers are from ASUS and EVGA both (but made for Windows Vista)

I would doubt that it's Win 7 causing the problem in and of itself. Sounds more like you have the video drive in windows set to high for the TV. Try reducing the resolution a bit. Check the TV's manual to see the max resolution it can do.

Unfortunately, I don't have the full manual (this set's a hand-me-down from my mom, who lost the instruction CD-ROM while in the first stages of Alzheimer's-my sister brought it for her.) I suppose I'll have to check the PDF super-instruction manual I've got somewhere. Does that help, guys?

As a test, you can try lowering the resolution in windows to something like 1024x768. That will get you higher than safe mode but is lower than 720p should be. If you still have a problem at that resolution, then yeah, it could be a hardware problem.

Before you start buying extra stuff, I'd recommend checking if your TV is running the latest firmware, and the same for your graphics card -check if there's a newer driver available.

Now, I'm still using an analogue TV-set, so I actually don't know how to do this, but I'm sure the manufacturer has something about it on their site.

VGA cable connection is your problem, use a better connection like DVI or HDMI.

I don't know if I have a HDMI or DVI connection on my videocard.

How do you have your TV connected to your PC? VGA? DVI? HDMI? What video card do you have? Have you updated your video card drivers to the latest version?

All those can make a difference in how well you PC and TV play together.

Oops! I just saw everyone asking the same questions already. Disregard everything except the drivers part. You said the drivers were made for Vista? If later drivers aren't available then you might need to upgrade your videcard if it's a slot card. If it's integrated graphics, you might be SOL.

 

[Brent]

What video card do you have specifically, EVGA what.....?

If you are not sure google GPUz download it run it and report back what you have specifically.

 

[Dusty Ayres]

My videocard card is a NVIDA GeForce 8500GT, my motherboard is a ASUS M2N-E,my CPU is a AMD Athlon 64 dual core...that's about it.

 

[Asbo Zaprudder]

I believe that the LG 32LG40 has a maximum native resolution of 1366x768 at 60Hz if you use an DVI-D or HDMI connector. LG don't quote the VGA resolution, but consider that the TV will have to do an A2D conversion on the input, which might well reduce the usable resolution to 1280x720 or even lower. I thought that the NVIDA GeForce 8500GT included a DVI port.

 

[Brent]

Depending on what make and model that NVIDIA GeForce 8500GT video card is, it should have a DVI port (it will be a bigger white port usually (sometimes its black though)). That is the better connection to use.

Yeah, some cheap ones might well not have a DVI port.

To the OP: if there is a DVI port, make sure to use the digital rather than the analog portion of the port -- you'll require a DVI-D to HDMI lead, or a DVI-D to HDMI adapter plus HDMI lead. Don't use a DVI to VGA adapter-- that only uses the analog portion.

Amazon has DVI-D to HDMI cables, that's what I am using right now.

To earlier poster - I am pretty sure I have a 32LG40 and it runs 1920x1080, but I'm not going to dig to be 100% sure it's the 32LG40. My video source shows the model name of my receiver now, so, can't use that.

I'd agree that using VGA is probably your problem.
