(of course this is first right)
b) Motion smoothing
(because i'm extra sensitive to low FPS - I actually like SOE)
c) Low input lag
(for the online twitch games)
(once you use a huge screen for a PC, you can't go back)
e) Windows text quality
(hard to live with fuzzy text)
Probably in that order although they all weigh heavily in my decision making.
Now after going through several displays (through the help of Fry's/Best Buy return policy), from Samsung, Sony, Mitsubishi, Panasonic, Toshiba and even Hitachi , I've narrowed to two Samsungs. Now mind you, this isn't because they are the best displays out there, not by any means. Just that they seem to be close enough to what I'm looking for and frankly, I'm getting pretty tired of the endless searching, returning and testing.
Now ever since I got the B650, I must admit that I was becoming attached to it, despite its ugly chin design (what were they thinking). Its whites are just a tad whiter than the a750, the blacks a bit more black. There's just a bit more POP to the picture, perhaps because of slightly better contrast. Note the words, 'just a bit more' - we're not taking a huge difference here! Both have the lovely gloss screen, although the b650 does suffer from slight flash lighting from all four corners, it makes up for it with its ability to have a darker overall black. I was also liking the new customizable AMP settings.
I thought for sure the b650 was going to be my keeper. That was until... I did the lag tests.
Yes, that's right folks. I'm sad to report, It looks as though Samsung has made their displays SLOWER
this year than last.
Before I show you my screenshots, Let me first explain why I post primary vs. secondary screenshots. It's because, at least in my setup, it makes a difference. The Primary display (in clone mode) throughout all my testing always seems to have nearly a frame advantage (about 16ms). So always take note of that when you see my screenshots! The primary display has a slight advantage in speed.
So if the primary is losing to a secondary, then you KNOW it's bad!
Without further ado, here are the numbers (B650 on left, A750 on right on ALL pics
Samsung b650 hdmi1 AMP sliders maxed vs Samsung a750 AMP on High: Both no Dynamic contrast or black enhancements - b650 primary
Samsung b650 hdmi1 AMP sliders maxed vs Samsung a750 AMP on High: Both no Dynamic contrast or black enhancements - a750 primary
Samsung b650 Hdmi1 named "DVI PC" vs Samsung a750 HDMI2-PC - b650 primary
Samsung b650 Hdmi1 named "DVI PC" vs Samsung a750 HDMI2-PC - a750 primary
Samsung b650 hdmi1 named "HDMI1-PC" vs Samsung a750 named HDMI2-PC - b650 primary
Samsung b650 hdmi1 "Game Mode" vs Samsung a750 HDMI2-PC - b650 primary
Samsung b650 VGA Mode vs Samsung a750 HDMI2-PC - b650 primary
So it looks as though I'll be returning the b650. I just can't in good conscious choose the b650 over the a750 knowing the PQ is only slightly better but at a cost to input latency in every mode. Perhaps to some of you guys however, it may be worth it. Also, I should note that the b650 would cost me $150 buxs more than the a750.
BTW just so everyone knows, EVERY panel i lag tested these past few months was ALWAYS behind my GF's panny 32lz800 as far as lag, even a samsung in VGA or HDMI2-PC mode. As far as I'm concerned it IS the lag king. Now if only Panny would make them in larger sizes with 120hz.
