Making new TFT work

Only in so much as faster response time for games will be better, it is
not a strict comparison - just that for TFT response time *does* matter.

Yes - irrelevent for most typical business use.

Yes, TFTs with slow response time when displaying fast moving images
may end up blurring - recall early DSTN displays on document "page down".

My TFT (samsung 710V) gives me blurred "bars" down the screen at anything
below 72hz :S

That sounds like the effect of getting the pitch setting wrong, it'll
just be coincidence that it gets it right at the higher frequencies.
Check the monitor's OSD menus. This may help for "tuning", make sure you
display it at 100% scale:

Does it follow that 16ms ~ 62.5Hz
and 14ms ~ 71.4 Hz

And this kind of comparison is only remotely useful for fast changing
images.

(for static images (eg reading text) it is more or less irrelevant,
cant beat a TFT for reading static text except with pen and paper)

 And the issue, rather than lack of persistence, is too much of it,

Most 15" TFT run at 1024x768 native.

Games tend to involve action initiated in the peripheral vision.
o The peripheral vision is more susceptible to flicker
---- if you view a traditional CRT TV head-on it does not flicker
---- view it sideways on in your peripheral vision & it may flicker
o The point at which flicker is not detected is termed fusion
---- the critical fusion frequency (CFF) is generally 67Hz for most people
---- most people means a distribution, some need less Hz, some more

Whilst CFF is generally 67Hz it has been shown that reading performance
can benefit from frequencies >85Hz and in some cases >110Hz or higher.

Whilst games don't involve much in the way of reading re saccadic
movement, they do involve a lot of peripheral vision processing. The
peripheral vision is still heavily involved in low-level cognitive fight
or flight reaction programming - so may be frequency sensitive.

o For a CRT displaying both text & games refresh frequency matters
---- 85Hz is a typical minimum, not difficult on modern CRTs
o For a TFT displaying text, refresh frequency nor response time matter
---- exception potentially being on scrolling text re reading/searching
---- however we are a long way on from slow DSTN TFT (v Active TFT)
o For a TFT displaying games response time matters
---- that will probably have a direct impact on cognition/vision
---- a TFT with a response time of 20ms is potentially 50Hz

So whilst setting a higher refresh on a TFT doesn't do much, picking
a TFT with low response time for dynamic tasks can be very important.

High framerates in most games mean faster response to input, even if you
can't see the resulting change. I think it's more teenage reactions than
teenage eyes.

Try and find an LG and an Acer with identical spec on the same shopping
site, the more expensive of the two will most likely be the rebranded one.

It's still the rate at which the screen gets completely re-written, but
with a TFT you didn't need to re-write the screen (since it's basically
static) unless it changed. Some people with teenage eyes seem to think
they can detect 100 FPS or even higher .. me, I just get bugged if I can
see the flicker, which with a decent TFT/CRT I can't, even at fairly low
refresh rates.

Hi all, I set windows to "default monitor at 1280x1024 at 60hz", plugged it
in and i'm typing on itnow! Yerrha.

I'd recommend the Acer AL1912s to anyone, excellant value for money, and
cant see a dead / stuck pixel on it anywhere.

Tim..

I wonder if that is the rebadged LG monitor that I have....

...unless mine could be a rebadged Acer...!!!

Cheers guys i'll try that- it is an Acer 19" L1915s actually!

Tim..

On the two TFT's that I have they both run at 1280x1024 at 60Hz but I have
noticed that one of them (LG 19" L1915s) will also support 75Hz, even though
60Hz is recommended.

Understanding that TFT's don't have to "refresh" as the CRT screens do what
does the 60Hz or 75Hz refresh rate actually mean with a TFT, do you know...?

It's fairly meaningless for TFTs, I think they just allow a range of
frequencies to make them more flexible. The advantage of 75Hz is that
you may get higher FPS in games, or smoother video playback, if they're
set to sync with the monitor refresh. Should be negligible though. The
disadvantage is that it will be nearer the monitor circuitry's bandwidth
limit, so quality may degrade slightly, especially with an analogue
connection.

know...?

Nope, not a clue.  I've just checked this one (Dell 17" TFT) and can set
that to 75Hz, too, but absolutely no visible difference..
Good that you mentioned the res. - all 15",17" and 19" TFTs I've used
run natively at 1280x1024, so OP should probably use those settings if
changing refresh rate doesn't help.

Yes, refresh speed should be 60Hz for most TFT displays, so either
reduce it to that or install as 'default monitor'.
