I have a PC connected to my26"/27' Toshiba 26HF85 HD wide CRT TV (used for gaming and emulation) through a DVI-I to HDMI cable so it can use analog and digital signals, and recently read that 1080 vertical height was actually only 21 or 22 inches on a screen which explains why i may be seeing dead pixels on peoples 40' 1080p TVs since half the image isn't even onscreen unlike 4k 40' tvs with a 4k image being sent, so i thought to myself lets see what the good old HD CRT TV can do. What i found was ASTONISHING! my tv does 2880x1620p widescreen 16:9 Ive even managed to get 3072x1792p and heres an image that may give a better idea. http://i.imgur.com/38KAfS1.png technically my DVI-I to hdmi should do a signal of 3,840 × 2,400 which is about a 40' screen but my TV wont use that resolution, and is in between 1080 and 4k. So my question is since 2880x1620 or 3072x1792 equal about 26/27 inches(again a theory in my mind) and work, is the reason i cant use 3,840 × 2,400 actually because of the size of my crts screen and electrons just realize theirs no more screen and stop? for example if i upgraded to a 34" SONY KD-34XBR960 which uses the same tech but way better screen(text in windows is sharp without eye strain) would i be able to use a higher wide screen vertical resolution?

Wat?? The relationship between resolution and screen area is entirely dependent on the dot pitch. Also CRT HDTV aren't fully analog such as a multi-sync computer CRT. They, like LCD, plasma and the like have a fixed native digital resolution of the display processor. The analog raster is calibrated specifically for that native resolution, which in your case is probably 1080i. Any other resolutions are digitally scaled or cropped to the native resolution by the processor...
