Question about LG Flatron F700P 17" CRT Monitor

1 Answer

Color not stable.

I just bought this monitor last year. After bought it, my friend tell me that it have like some inner curve, not to its resolution but its screen. I thought its still ok then i let it go as it. When its going about a year old, the color becomes unbalance/trouble. Sometimes it not have color except grey and very sensitive when have some / a little shaking. When its ON for a while(15minutes), then its become OK. But it is just sometimes. And sometimes will going bad again. I really dissapointed of this expensive monitor. At top of view is ok and clear, and at bottom i think its little blur. What is the problem. Is it just a small problem and can be fixed without expensive cost? Or should i buy a new one. I work with computer and little confuse about it because it still can be use as normal when OK and going bad sometime and make me very disapointed! Please suggest me.

Your description sounds like a unit with cold solder joints or a bad capacitor. It sounds like you have the skills to check the 1st problem. Remember safety. If you can solder remove the back and solder all the connections on the main circuit board. Give this a try. This could easily solve your problem. Probably more than half of these kinds of problems are related to poor solder joints. If this doesn't fix it finding a bad capacitor could be more than you are capable of, which means you may need the assistance of a qualified repair tech. Good luck.

Dim monitor issu. I want it bright always.

it could be age-related but there is also a power setting in the OS. Alternately you can check also the monitor OSD and see if there is a setting for adaptive brightness enabled

Want 1400x1050 resolution

It depends on the monitor too, and the refresh rates it can support.. But it seems to me that 256 MB is rather skimpy. Try changing the resolution to 1200x800 first. If the monitor or screen can handle it and it remains stable and no hangups in games or other demanding programs then try to change to some other higher resolution. Before you make any hazardous step backup your computer or set a restore point. In case of trouble you will be able to load the last configuration that worked.
Good Luck.

Good day, I have an Acer AL2423W monitor. When I turn it on, for the first few minutes all I get are vertical coloured lines. After a few more minutes the screen images start to become visible, but...

Hi Friend, In this case what I would recommend you is to connect any external monitor to the system to check if you have the same issue with the external monitor as well or not.
If yes, then it might be the issue with the video card so, you can try updating the video drivers for the system.
If no, it means that the original monitor has some issues with itself..
Also what I would recommend is try to lessen the screen resolution instead of 1920 x 1200 to lower resolution and restart the system and check if it makes any difference..
Also update the video drivers for the system.

Need to set the color to 6500K

No, the manufacturer is the one to contact on what resolution is best for your project.
Most monitor are already set for best resolution for photos and movie view and also media editing so you should be OK
if your monitor is a recent model at 16500X780 or it says that is 1080p or 1080 i then you should have no issue with the color setting.
You can go to the control panel and set the display settings for hue, color , contrast and brightness if your Monitor has a graphical user interface for it. Check your user manual for color adjustment for your monitor and also the video card that is install in the PC.
The "control panel will have the display setting for "true, and High color resolution.

Cant get monitor on.button on monitor turns green then to yellow when connecting cord. made sure connection was firm. monitor worked on other computer and computer worked with other monitor with the same...

This issue is weird, I don't know if the monitor you bought is new or not, or is there any changes done in the computer prior to that issue. The only thing I could think of is there might be an incompatibility issue with the video card to the monitor you are using. I don't know if they have the same brand and model but if not, most probably that the monitor is not compatible to the video card.

Connection hook up problem

Set the resolution lower.

It is telling you that the resolution you want is beyond its normal operating range.

just drop it to lets say 800 x 600
Then bump it up one resolution at a time until you get the message again, then drop it back one.

Running monitors above the acceptable range can drastically shorten their lifespan.
With lcd monitors you are much better using the DVI cable if yout video card supports it.

Nvidia geforce 9400gt 1gb card problem

The maximum performance of your video card is limited by the hardware you attach it to. In the display properties of Windows, your highest resolution is 1280x1024 because your monitor is not able to go any higher than this. This resolution is a typical maximum for a 17" monitor. Some 15" can do this, and some 19" can do this. In order to get a higher resolution, you'll need to get a bigger monitor with a higher native resolution. For example, a nice 24" monitor can only do 1920x1200. The video card can go higher, but it's limited by the monitor. 32bit color is your highest setting - that's 16 million colors. Your video card's 1GB of RAM only determines how much rendered data (usually 3D) it can store and move at any given moment, which is related to but not determined by your screen resolution. That's a very nice card - you should be able to get very good frame rates, color, and performance out of 32bit color and 1280x1024. If you want a higher resolution, you'll need to get a bigger monitor.
