    Don't know if I'm replying to both of you at once, to the whole blog, or whatever. But, I thank you both-- c-tekk and aaclevy -- for your prompt reply. Let me see if I've gotten this straight, as I am pretty much non-techy, just following some guidelines I found online: I simply don't know if tv is lcd or not, am almost certain it's not hd. About six or seven years old--Panasonic, PanaBlack, if that helps. The tv doesn't have vga in--component video, I think it's called. And compu has vga out. Thanks for the help. I'm giving you both thumbs-up.

Most TV have interlaced 60, which is really 30 hz...

You can set your computer's scan frequency by right clicking on desktop, then going to the rightmost tab, under advanced, click on the monitor tab and select 60 from dropdown tab...

However, most videocards output Svideo to tv, not VGA so don't worry about it. if your TV has VGA in, you can select 60, but if it has VGA in, it probably has greater than 60 capabilities... but 60 is rock safe for everything.

Just be sure the Tv is LCD ....And make sure that The REFRESH RATE (scan frequency, you call it)....matches on both the pc and LCD tv....

Even if the tv isnt lcd.... you can use a tuner card for a CRT tv.....

But I recommend LCD HDTV...a high end one!

I actually am using my 40" WS Sony HDLCD TV....

Most TVs that can support a PC (HDMI or RGB) will automatically cause both the TV and PC to operate on the same Refresh Rate.....

Monitor displays frequency out of range.....need help . How can I solve this?


The frequency is out of range because the VGA graphics card is not compatible or set right for the monitor's set of frequencies that it can work with.

Try another VGA graphics card.

Or upgrade the card to one with DVI, and upgrade the monitor to one of those 24" DVI Samsung monitors. They're nice. I got one from Best Buy a few years ago, and never regretted the larger desktop.

Good luck on this one.

Frequency out of range


the monitors resolution range is only to 1280X740 or 780
and your video card may also need an upgrade.
The game may require a higher resolution that is not compatible with the the devices mentioned.

My monitor has gotten really dark. How to fix?


Try another monitor on your computer. If the other monitor works fine, then you know the video card is good and the monitor is definitely bad.

If the monitor is the culprit then the only option is to replace it because that would mean the screen itself is going bad and there is no replacement screen for that monitor.

EMachines E19T6W monitor turns itself off and on.


First off, I would check the monitor, if it is getting very warm, I would use a can of compressed air to blow the dust out (make sure it is unplugged first!). Second, I would check for any sort of interference in the vicinity (speakers are a huge cause of problems in Monitors) such as magnets.

This monitor worked great for exactly one year from the purchase date. The day the one year warranty expired, this monitor completely went blank, and will not even turn on. An uncanny coincidence or a...


I vote for both. It's an uncanny coincidence if eMachines last more than a year and they may be programmed to be obsolete shortly after that.

eMachines are not a fav of mine, and I certainly feel your anguish. Maybe your dealer can do something. It's worth a call.

Monitor trouble


Check the game settings requirements. You might have to switch your display resolutions in order to get the games to work correctly.

It's supposed to automatically switch but since it goes blank and searches for frequency that indicated a video related problem.

X2gen 19 inch monitor


It sounds like a heat problem in the monitor. It could also be a computer graphics problem. Leave either the computer or the monitor on for a while and then turn on the other device. try to discover which is needing to be warmed up. The buzzing and problems with the other RF devices around mean that the monitor or computer is emitting frequencies so it will affect the TV and maybe the computer. I found my computer emits these frequencies. I can't listen to AM radio when the computer is on.

Weird blink problem...


That's definitely a hardware (incompatiblity) problem. Download the most updated driver for the graphics card. Also see if there is a monitor driver for the monitor.

I understand it worked seamlessly for the emachine but you should switch it back for a day or two to rule out the monitor just screwing up.
