Interesting. I wonder if it does PAL, NTSC and SECAM *properly* ..... I recently obtained an NTSC-compatible TV for my multitude of NTSC hardware. It displays PAL correctly, but it displays NTSC by converting it to PAL and then running it through the usual PAL delay line matrix. This looks okay on television images but for computer work it's just not proper NTSC. For example, mixed colours used in games such as Mayhem in Monsterland come out properly mixed, whereas a real NTSC display would show them as alternating lines of different colour. It also displays SECAM by converting it to PAL, which is truely *horrible* as you get both SECAM and PAL 1 line artifacts, and when you consider that the SECAM C64 works by converting PAL to SECAM, the net result of my SECAM machine on this TV is that colour encoding artifacts bleed 2 lines into the image below. Terrible! I need some proper multistandard devices...
