LCD with same panel type, ie TN

[nealh]

We see so many LCD on the market with the same panel, yet IMHO when looking at a store displays(taking into account incorrect resolutions) some them look better than others

I do check contrast/brightness and try to even that out

for example the newer Samsung 932B looks crisper than many of the WS models ..VX1935wm..they both seem to use the same TN panel

is this becasue Samsung tweaks them..or is really just an issue of 1280x1024 vs 144x900 or 1680x1050 not being displayed correctly....

It's usually a function of the gamma correction of the panel (a lower gamma correction factor will produce a darker and crisper image). The gamma correction is many times the same as the one provided by the reference sample (the panel manufacturer's, like AUO's or LG Philips LCD's). Resolution will not affect colors, and interpolation will not affect them by any significant amount either (just a tad around adjacent pixels because of blending).

Some TN panels are just simply much higher contrast than others. Typical TNs (e.g. Samsung 710T) are 300/400:1 and the new ones (e.g. Samsung 226BW/LG L226WT) have raised that standard to 800/1000:1.

thanks

so is there a way to determine the Gamma prior to purchase

the Monitors I have looked at recently are the

Viewsonic VX1935wm/VX2035wm

Samsung 932b

all 3 are TN panles with 5ms, 160 degree viewing angle and 300cd/m2
Viewsonics are 800:1 contrast ratio, Samsung is 700:1 butalthough Samsung advertises a 2000:1(DC) contrast ratio

so are you better off buying Samsung or Viewsonic...

damn so confusing...not sure who has better support too

Smaller AU Optronics panels tend to be on the bright side when it comes to gamma (they look a little washed out). Bigger AUO panels such as the BenQ FP241W have better gamma control.

ViewSonics tend to use AUO panels and for that reason I tend to veer away from them.

Samsungs have better gamma control than the smaller AUO ones by a good margin, although LCDs manufactured by LG take the cake. High contrast LG TNs tend to be the best for color.
