Do you suffer Headaches from LCD screens

Set it at 75khz or more.

(You may know how to do this, just posting for others benefit)

Desktop right click
Properties
Settings
Advanced
Monitor tab
Screen refresh rate Pull down menu (Should be a number of refresh
rates)

If your video adapter won't do 75khz, at least change it to
anything higher than 60khz.
Click to expand...
It does not give me the option to do above 75 unless the resolution is lower than rated 1440 X 900...

It would be nice to be able to easily toggle between different refresh and resolution rates. Might use one for web browsing/text and another for picture editing. There is probably shareware out there to do this.

You also might look at upgrading your video card for a card that would support your native resolution with better refresh rates.

There are tons of formally cutting edge video cards out there that can be had for very little $$.

Not so! I Have a 17" AG Neovo LCD running my computer on DVI and as a hobby I repair computers (usually for little or nothing). My monitor has connections for simultaneously connecting DVI and D-Sub and so when I have a computer to fix I run my computer on the digital and the broken computer on the analogue, constantly switching between the two I notice a massive difference, there is now way I would accept D-Sub anymore, even if it meant spending an extra £100.
 
Thanks for that Photosmarty...I will look into a new graphics card..any advice I have a radeon 9000 128mb at the moment and run an Athlon 2600xp with 2gb ram

I have a (very) old MSI 4800se, which is a great card (well was in its day, and very expensive). Two questions......

1. Does your monitor have a DVI cable with it?
2. Do you play complex up-to-dat 3D games?
3. I take it your graphix card slot is AGP?

If you can answer.....

1.yes
2.no
3.yes

then I think this one would do you fine....

Nearly 2 year old technology, but puts in some very impresive performances.
 
Heath I am not sure how your eyes are ...but years ago my eye doctor asked if I use a computer and to measure the viewing distance ...

So I spent some time figuring that distance and got glasses for 24 to 29 inches....he calls them computer glasses.

They are no good for normal wear or for reading but they are perfect for the computer.

And I can tell its time for a new pair as I am moving back to about 33 inches for the best viewing.
At the time I was using a 19 inch CRT and now I am using a 19 inch LCD.

No but son does occasionally...
yes i think

I must be totally out of touch with prices... I was expecting to pay at least £100... was looking at a 256mb card and probably a radeon again...but which one I havent not a clue..

Oooops....dont bother with that link they are out of stock, cheapest I could find was Ebuyer http://www.ebuyer.com/UK/product/112761/rb/21977363269

or pixmania have it too for a bit chaeper
 
Hi Gene,

Were you wearing glasses anyway at that time? the reason I ask is that yesterday I had my eyes tested and and I have no problems and dont wear glasses as of yet...what is the refresh rate of your screen Gene..

Well......you get what you pay for I suppose. In a test of the above card, take note I reposted where it is in stock!, they ran Call of Duty a 3d war game maxed out comfortably with just a little slow down. So a modern 3d game would more than likely work albeit at lower resolutions and less detail.

If you have a bit more (cash) laying around you could jump to this.......

http://www.ebuyer.com/UK/product/105565

an apparantley excellent all round card (still wont play new games in all their glory) supports tv in and out and HD out, its called AVIVO and is all singing and dancing......

...to LCD's:

Much of the discussion of refresh rate does not apply to LCD monitors. This is because while a phosphor on a CRT will begin to dim as soon as the electron beam passes it, LCD cells open to pass a continuous stream of light, and do not dim until instructed to produce a darker color. Pertaining to LCDs, see also response time.

Yes Heath I have worn glasses since 4th grade and bifocals since I was 50.....it was the doctors Idea to cover this medium distance ,when I retired and started using the computer more.
And I really struggle without them now that I have become accustom to them.

I will be darned if I know the refresh rate but its a 3 year old Dell so its nothing very modern.

Heath,

Sorry for butting in so late in the thread.

First of all, I don't think you should try to alter the refresh rate on an LCD. You cannot compare refresh rates of an LCD to a CRT and in the same way that you shouldn't alter your screen resolution from it's native resolution, you also shouldnt alter it's refresh rate as the quality of your display will deteriorate.

Secondly, use DVI if your monitor has a DVI connector. It is again much better for the quality of your display.

As for graphics cards; No need to buy anything too fancy. You won't see any benefit from it for image manipulation. Unless you play hte latest games I'd stick to something below the current crop of graphics cards as it will save you a lot of money. Personally I don't like ATI's that much and prefer NVIDIA's. I find the drivers much better.

Try and pick up an XFX 128Mb NVIDIA Geforce 6600GT which is what I use and can be had for £46 (providing you had an AGP slot). It runs all the games I've thrown at it, is reasonably cheap and has two DVI connectors. One thing you need to find out is what graphics card interface is in your PC as graphics cards come in two flavours; AGP (not that many around anymore) and PCI-E.

Lastly, if you do decide to buy a new card, try http://www.scan.co.uk and keep an eye out on the today only section which changes every day and bargains can be had.

Sorry, LCD's do not "blink" they are a constant uninterupted light source, they do not act like Flourescent tubes which is a gas that gives off a pulsing light, still not a "blinking" light. You cannot be allergic to flourescent light, it gives off no radation as such. I think you may be sitting too close to the LCD monitor, that seems to cause a person to focus too closely which will cause headaches, but it is not caused by any blinking, I do not care what this teacher says. LCD is probably the safest light to look at. If you have headaches looking at Flourescent light, then you apparently cannot go outside, the sun gives of a light very similar to flourescent light, just a wider spectrum of light waves but it is a gas giving off the light and it pulsates.
 
How about:-

http://www.scan.co.uk/todayonly/ which really means today only (till Monday AM)

and look for the 256Mb XFX 6800 XT, Mem 1000 MHz, GPU 350 MHz, 8 Pipes, Dual/DVI-I/S-Video at £75.19. Details link here:-

http://www.scan.co.uk/products/productinfo.asp?WebProductID=473672

or the 256MB XFX 7800GS Extreme ,Mem 1300 MHz ,GPU 440 MHz,16 Pipes, S-Video/TV Out , D-Sub , DVI-I (AGP) at £193.88 if you really want something a bit more up to date.

I always preffered the NVidia chipsets and currently use two Gainward 256K 6800 Golden sample overclocked and water-cooled cards in my two 'main' development machines. I know you're dubious about the benefits of DVI, but I've worked in the computer industry all my working life, and anyone who uses HD-15 VGA to connect a DVI capable LCD monitor is probable degrading their image by literally 50% (and that's not an exaggeration).

Oh... and ignore refresh rates for LCD screens. 60Hz is standard and you won't get any flicker. I used to run the Sony CRT at 85HZ 1280x1024 because my eyes are sensitive to flicker as I spend so much time in front of the screens, but 60Hz LCD's are better by far.

stresses in your life at the moment. a few years back i started getting headaches, and my doc put it down to stress.

also at the same time i got the headaches i was into games consoles, stoped playing them because i worsend and started vometing. my repeted doc visits and my own little reserch now pointed towards motion sickness from the games i was playing.

even now, watching a friend for only 5mins on a games console, i start trembling, get a slight headache, and then feel sick and have to go into a diferent room or enviroment and slowly start to feel better. strange i know.
but it also wouldnt hurt to visit your doctors.
