I could be wrong but I believe they can both (the 600 at least, I'm fairly certain), CAN accept 1080p... just obviously, not natively as the resolution isn't high enough. But I think it can accept the signal. So in theory, the TV would be downscaling the, in theory, if it's done right, best picture possible. Which ain't no bad thing!
Both sets are 720p,LXD60 max res 1080i .LXD600 adds 1080p to this. You've also got a VGA dsub for PC connection and SD card slot which I think someone else mentioned. Either of these sets are great and well worth your pennies and IMHO the latter of the two is the best LCD out there at the moment, also if you like the 600 there's a string on here somewhere.They are both 1080i max input.
The differences are mainly that the sound system is apparently better and there is an SD card slot which will record and play lowish quality video. The display also has slightly enhanced software to provide subjectively better quality.
I decided these addons weren't worth the extra cost for the 600.
I would probably steer well clear of sOnY's so called budget LCDs(s,u and v series) better options out there unless you're a Fanboy I'd guess . I think the LXD60 has been on the market since april/may06 so I would expect some info on its replacment about that time in 07, though I'd think it isn't going to have a VGA input....LXD600 for all the bells and whistles mate.From memory, the Bravia smearing effect can be fixed by turning off something in one of the menus, though the 26" S-series apparently uses an 'inferior' panel to the 32" model.
Does anyone know whether the TX26LXD60 will be replaced anytime soon? It has been in the shops almost a year which these days seems a long time for any LCD TV
(Please Panasonic give any LXD60 replacement a PC VGA input, but there again it could be an excuse to save for an LXD600 or wait for the Sony U2500 series which will have 2xHDMI and should be available in a 26" size.)
